4.3.4 Electrical connections
Only the 37-pin D-sub sockets can be used on which a Flow-X module is actually installed.
The three 9-pin D-sub connectors are the serial ports of the display module. These ports
can be used to communicate with devices such as a gas chromatograph or a DCS. COM1
supports RS-232 only at Flow-X/P. COM2 and COM3 can be configured individually for RS-
232 or RS485.
LAN1 and LAN2 are Ethernet connectors for connecting your Flow-X/P or Flow-X/C to your
network. The Flow-XP modules are used in multi-module operation.
