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.

Network page

Item

Description

Configuration Method

Enable/disable the DHCP server. If the DHCP server is disabled, the IP address of the device has to be set manually.

IP Address

IP address of the device.

Netmask

Netmask associated with the IP address.

Gateway

Gateway address currently used by the device.

MAC Settings

Allow setting the default MAC address or typing it manually.

MAC Address

Allow changing the physical address of the device.

Item

Description

HTTP Port

Determine the port of the control panel.

Telnet Port

Allow connection with the device via Telnet.

Broadcasts

Notify RemoteCOM clients in the same network about this device's existence. With this enabled, the Configurator will automatically set most of the settings correctly after picking the correct port.

Hostname

Label that is assigned to the device.

DNS Address 1 (Primary)

Primary Domain Name System used by the device.

DNS Address 2

Domain Name System used by the device.
