* In the C32 converter user should use only RS232 or only RS485 interface of one port as they occupy the same internal bus of the device. It means, don't use pairs: RS232-1 & RS485-1 at the same time and RS232-2 & RS485-2 at the same time!

Frame ground FG

Electronic circuits are constantly prone to electrostatic discharge ESD. Redisage Electronics modules feature a design for the frame ground terminal block FG. The frame ground provides a path for bypassing ESD, which provides enhanced static protection ESD abilities and ensures the module is more reliable. Connecting FG terminal block to the earth ground will bypass the ESD disturbances outside the device so will provide a better level of protection against ESD.

Frame Ground FG connection reference drawing is provided below.

If earth ground is not available FG can be left floating or it can be connected with the power supply GND.

Configuration by the Web Page

Serial Port Server w/ Wi-Fi® (C30 - C32)

This page presents capabilities of the Ethernet Converters configuration. First of all, make sure that converter is connected to power supply and to the LAN using a patch cord. If the device has not static IP set up, it will be necessary to obtain its IP address in the local network. User interface is mostly similar for every converters but some subpages might be diffrent for several models depends on amount of interfaces. In order to avoid some issues, click on a “Help” button in the top right corner on every page.

Default configuration

Default configuration of the Ethernet Converters:

Default login details:


Login

To access the web page open the browser, type IP address of the converter (default is 192.168.100.100). Then log in using user’s personal credentials. If it is a first configuration or the converter had a factory reset, then use default login details (login: admin, password: admin123).

image.png

The configuration is available only if devices are connected to the same Local Area Network as the computer used for it.

Status page

After a successful login, there should be an insight to important information such as port status, service and port which are in use and more details about the connection.

Item

Description

Service

RemoteCOM

The RemoteCOM option lets to attach the port to a computer running the Redisage Configurator as if it would be physically present in the computer.

TCP Socket

TCP/UDP Socket exposes this port as a regular network socket - connect to this socket with own software and write/read data to send/receive data over the serial port without any additional software or serial port handling.

UDP Socket

Port

The service number - the device has an “IP Address” by which it is identified and a couple of services running on it. It's required to tell the device which service should be in use by entering this device's IP address and the port number in the RemoteCOM client or user’s software.

Connection Timeout [s]

The time specifying how often (every how many seconds) the "keep alive" packet will be sent to check if the client is still connected. Value 0 means that the connection is kept permanently without any timeout.

Inactivity Time [ms]

The maximum allowed time in milliseconds during which there is no data transfer. When connection is inactive for the time longer or equal to the entered value, then it will be closed. Value 0 means there is no measure of the inactivity time at all.

Encryption

Determine how the data is protected 'in flight' over a network. It is available only with the RemoteCOM service. Once enabled, it is necessary to set the password.

Password

Protect the communication between the device and various clients - keep it secret! Same settings have to appear in clients - without the correct passwords, a client will not be able to connect at all.

Termination

Enable/disable termination on the RS line.

Baud Rate

Determine the port's transmission speed over the data channel.

Data Bits

Determine the number of data bits in the port's message frame.

Parity

Enable/disable parity check in the port's message frame.

Stop Bits

Determine the number of stop bits in the port's message frame.

Notes

These notes are for information only - feel free to write down anything related to this port (device it connects to, etc.). They're also shown in the Configurator during the device discovery - in the other words, they're public.

Changing port’s service closes all sockets connected to the ports.

In the UDP mode, port number 15051 is reserved for UDP broadcast service.

Network page

In this section, network settings can be changed according to target LAN parameters.

User Manual

Redisage Configurator‎

Serial Port Server w/ Wi-Fi® (C30 - C32)

Redisage Configurator is an app used to emulate connection between converter and a PC as if its RS232/RS485 ports would be connected directly to the COM port. The advantage of that functionality is lack of additional cables. Transmission can be tested over Ethernet. First connect the device to a local network using the Ethernet port and power it up. During the configuration process set “Service” to the RemoteCOM option on the “Ports” page.

While changing port service from RemoteCOM to TCP/UDP Socket make sure to disable RemoteCOM virtual port in the Redisage Configurator first.

image.png

Redisage VSP Driver

In order for Redisage Configurator to work properly, it is necessary to install the Redisage VSP Driver. It can be done with RedisageVSPDriver Installer available for Windows. You can download it for free here.

Redisage Configurator

When the device is configured open the Redisage Configurator app.

11350c46-7007-4fcb-add1-062c5c31ef21.png

Use the “Add Device” button to set up a new connection with a device. On the right side there should be a list of available devices visible. Choose one of them or specify a custom COM port number, an IP address and a service port number.

While specifying a custom virtual COM make sure to use the same IP address and service port as set earlier in the port configuration.

7d9e3ea8-6904-4f6d-b072-47b15c80d60c.png

In order to establish a connection with a desired device use the “Enable” button. To end the connection use the “Disable” button. Service IP/hostname, service port and password can be modified at any time. There are also available 2 options of the encryption methods (none (disabled) or strong (AES-GCM 128-bit, Argon2)) and 5 options of the connection timeout (brief, short, fair, modest or lengthy). Changes have to be saved with “Save Changes” button.

434ace32-b439-47be-b821-da79cef2b770.png

There is also the “Settings” tab at the top of the window from where the Logging Directory or the Device Manager can be opened.

ae6fd1d6-457d-4da4-82bc-99785acd103f.png

If everything is connected properly there should be a new COM port available in the Device Manager. It is also possible to check it, for example, on the web page.

If any change is made to the port configuration, make sure to apply it with the “Save Changes” button.

Troubleshooting

If a discovered device cannot be added, check if it hadn’t been added before with a different COM port / service port. In that case, delete previous configuration from the Redisage Configurator.

If that doesn't work, check if the port service was configured correctly for the RemoteCOM Service.

Modes of Operation

Modes of Operation

TCP Socket Mode

Serial Port Server w/ Wi-Fi (C30 - C32)

This article presents a simple instruction of a first connection between a TCP client and a RS232/485 device through the RemoteCOM Serial Port Server. Firstly, connect the RemoteCOM according to the diagram below.

Then, it is necessary to configure the RemoteCOM’s ports. It can be done, for example, via the device’s web page. Ports' configuration can also be done via the Telnet, serial or service console. Set the “TCP Socket” option in the “Service” field on the “Port” page. Check also if the port number is set correctly in the “Port” field. Set desired options of the RS232/485 connection (“Baud Rate”, “Data Bits”, “Parity”, “Stop Bits” - these options should be the same as in the RS232/485 device).

518960b3-054f-491f-afab-5ad319c53274.png

Now, the device should be ready to work. Once the TCP Client creates a TCP socket, the bidirectional communication should be available.

Test connection

Connection can be easily tested with a USB-RS232/485 converter and for example Hercules Setup Utility software. Connect the RemoteCOM’s RS232/485 port to the USB-RS232/485 converter and plug it in to the USB port of a PC. Open Hercules Setup Utility program and go to the “Serial” page. Set serial connection options according to the previous RemoteCOM’s ports configuration and open the COM port. Then, go to the “TCP Client” page and set the device’s IP address and port. After a successful connection, there should be the bidirectional communication available.

This article presents a simple instruction of a first connection between a UDP client and a RS232/485 device through the RemoteCOM Serial Port Server. Firstly, connect the RemoteCOM according to the diagram below.

Then, it is necessary to configure the RemoteCOM’s ports. It can be done, for example, via the device’s web page. Ports' configuration can be also done via the Telnet, serial or service console.  Set the “UDP Socket” option in the “Service” field on the “Port” page. Check also if the port number is set correctly in the “Port” field. Set desired options of the RS232/485 connection (“Baud Rate”, “Data Bits”, “Parity”, “Stop Bits” - these options should be the same as in the RS232/485 device).

63525652-3521-4885-aa5a-6af998d9a2d0.png

Now, the device should be ready to work. The bidirectional communication should be available after the device receiving a first message from the UDP client. Before that happens, all the data sent from the device to the UDP client will be buffered and sent later.

Test connection

Connection can be easily tested with a USB-RS232/485 converter and for example Hercules Setup Utility software. Connect the RemoteCOM’s RS232/485 port to the USB-RS232/485 converter and plug it in to a USB port of a PC. Open Hercules Setup Utility program and go to the “Serial” page. Set serial connection options according to the previous RemoteCOM’s ports configuration and open the COM port. Then, go to the “UDP” page and set the device’s IP address and port. The bidirectional communication should be available after the device receiving a first message from the UDP client. Before that happens, all the data sent from the device to the UDP client will be buffered and sent later.

Serial Port Server /w Wi-Fi (C30 - C32)

This article presents a simple instruction of a first connection between a virtual COM port and a RS232/485 device through the RemoteCOM Serial Port Server and the Redisage Configurator app. Redisage Configurator is used to emulate connection between converter and a PC as if its RS232/RS485 ports would be connected directly to the COM port. The advantage of that functionality is lack of additional cables. Redisage Configurator can be installed on Windows machine and requires the Redisage VSP Driver to work (it can be installed with RedisageVSPDriver Installer). 

In order to perform a setup, connect the RemoteCOM according to the diagram below (RemoteCOM should be connected via Ethernet to the same local network as the PC).

Then, it is necessary to configure the RemoteCOM’s ports. It can be done, for example, via the device’s web page. Ports' configuration can also be done via Telnet, serial or service console.  Set the “RemoteCOM” option in the “Service” field on the “Port” page. Check also if the port number is set correctly in the “Port” field. Additionally, encryption can be set to increase the security (it will also require to set up a password).

6f9c3d38-2582-4c34-ad2d-ab836d769687.png

Next, open the Redisage Configurator and click the “Add Device…” button. Available RemoteCOM’s ports should appear on the list. Choose the desired one and click the “Add” button.

d3ba1f43-7a53-44d4-832a-bd1f94849812.png

If a discovered device cannot be added, check if it hadn’t been added before with a different COM port / service port. In that case, delete previous configuration from the Redisage Configurator.

If that won’t work, check if the port service was configured correctly for the RemoteCOM Service.

Enable the virtual COM port with the “Save changes” button. If a password was set during the configuration, it will be necessary to type it into the “Password” field.

Description

Service

RemoteCOM

The RemoteCOM option lets to attach the port to a computer running the Redisage Configurator as if it would be physically present in the computer.

TCP Socket

TCP/UDP Socket exposes this port as a regular network socket - connect to this socket with own software and write/read data to send/receive data over the serial port without any additional software or serial port handling.

UDP Socket

Port

The service number - the device has an “IP Address” by which it is identified and a couple of services running on it. It's required to tell the device which service should be in use by entering this device's IP address and the port number in the RemoteCOM client or user’s software.

Connection Timeout [s]

The time specifying how often (every how many seconds) the "keep alive" packet will be sent to check if the client is still connected. Value 0 means that the connection is kept permanently without any timeout.

Inactivity Time [ms]

The maximum allowed time in milliseconds during which there is no data transfer. When connection is inactive for the time longer or equal to the entered value, then it will be closed. Value 0 means there is no measure of the inactivity time at all.

Encryption

Determine how the data is protected 'in flight' over a network. It is available only with the RemoteCOM service. Once enabled, it is necessary to set the password.

Password

Protect the communication between the device and various clients - keep it secret! Same settings have to appear in clients - without the correct passwords, a client will not be able to connect at all.

Termination

Enable/disable termination on the RS line.

Baud Rate

Determine the port's transmission speed over the data channel.

Data Bits

Determine the number of data bits in the port's message frame.

Parity

Enable/disable parity check in the port's message frame.

Stop Bits

Determine the number of stop bits in the port's message frame.

Notes

These notes are for information only - feel free to write down anything related to this port (device it connects to, etc.). They're also shown in the Configurator during the device discovery - in the other words, they're public.

Introduction

Serial Port Server w/ Wi-Fi® (C30 - C32)

Serial Port Server is a complete hardware and software solution for creating remote communication ports. The software part can be uploaded to any of the Redisage C30 - C32 Ethernet Converters. It provides a communication between a LAN host and a device equipped with RS232/RS485 serial interfaces. A dedicated app makes it easy and fast to configure and deploy. There is a possibility to create virtual COM ports with the Redisage Configurator to minimize number of cables. Onboard Wi-Fi module makes it even more versatile and independent solution.
