Phoenix Contact FL COMSERVER PRO 232/422/485 Serial Device Server

The Phoenix Contact FL COMSERVER PRO 232/422/485 is a second-generation serial device server that bridges a V.24 (RS-232), RS-422, or RS-485 serial interface onto a 10/100Base-T(X) Ethernet network in accordance with IEEE 802.3. Serial transmission speeds run from 0.3 kbps up to 230.4 kbps on the RS-232 port and up to 1000 kbps on RS-422/RS-485, with connections made via a D-SUB 9 plug (RS-232) or a pluggable COMBICON screw terminal block (RS-422/RS-485) and a single shielded RJ45 socket on the Ethernet side. The unit runs from a 19.2–28.8 V AC/DC supply, carries an IP20 rating for an ambient operating range of –25°C to 60°C, and mounts on a standard DIN rail in a 22.5 × 99 × 116 mm housing. Typical applications include serial cable replacement over a LAN/WAN, remote access to legacy serial instruments or PLCs, and Modbus RTU/ASCII-to-Modbus/TCP gateway duty when integrating older serial equipment into an Ethernet-based control network.

The PRO designation marks the top tier of the FL COMSERVER 232/422/485 family: where the UNI and BASIC hardware variants run fixed factory firmware for protocol conversion, the PRO unit is freely programmable in Phoenix Contact's proprietary BASIC programming language, letting the user write custom logic for non-standard protocol handling or application-specific serial-to-Ethernet behavior. The 232/422/485 suffix confirms the housing supports all three serial standards, with the active mode selected through the device's built-in web-based management interface.
