Data Sheet ESP32 Open IoT and IIoT Gateways (P01 & P02) Open IoT Gateway is also called as a PAC (Programmable Automation Controller). PAC products combine the functionality and openness of a PC, the reliability of a programmable logic unit like PLC and the intelligence of I/O modules with flexible software tools for a wide range of applications from data acquisition, process control, motion control to energy and building management. Our PAC family includes FreeRTOS PACs and MicroPython PACs for different requirements in OS, CPU and development platform. The P01 and P02 Gateways are based on ESP32 Xtensa LX6 . P01 P02 Features Open IoT gateway ESD protection for the RS485 data line Power supply: +12 to +30 VDC Transmission speed up to 115200 bps Tx, Rx and power LED indicators RS485 embedded termination 120 ohm Optional WiFi ® Operating temperatures: -40°C to +75°C DIN-rail mounting Dimensions: 90x56.4x22.5 mm 3 years warranty Customization of OEM is welcomed Specifications‎‎‎ Redisage PN P01 P02 Ports RS232 - - RS485 - - RS232/RS485 2x 2x Microcontroller ESP32 Wi-Fi ® N/A 802.11 b/g/n 150 Mbps / 2.4 GHz SMA socket connector for 2.4G antenna Tactile switch Power Voltage 12-30 VDC Power < 1 W Frame ground protection yes Baud rate up to 115200 bps LED indicators power, link activity, programmable RGB RS485 termination 120 ohm manually enabled Connector RS232/RS485 8-pin terminal block max. 2.5 mm 2 wire Power 3-pin terminal block max. 2.5 mm 2 wire Ethernet RJ45 Transmission distance RS485 max. 1,200 m at 9.6 kbps; max. 400 m at 115.2 kbps (Belden 9841 2P twisted-pair cable, if different cables are used, the transmission distance may change) RS232 max. 15 m at 115.2 kbps Mounting and enclosure DIN rail, plastic PA - UL 94 V0, black/green Temperatures -40°C to +75°C operating and storage Humidity 10 - 90% RH, non-condensing ESD protection ±4 kV contact discharge / ±8 kV air discharge Certification  CE, RoHS, EMC, LVD Norms 61000-6-2 - Immunity standard for industrial environments 61000-6-4 - Emission standard for industrial environments Variants P01 - Open IoT and IIoT Gateway 2x RS232/RS485 In the P01 gateway 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! P02 - Open IoT and IIoT Gateway 2x RS232/RS485 + WiFi ® In the P02 gateway 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.
