CARD-COM4

This card adds additional RS232 and RS422/485 connectivity to the Solo controller.
It features 2-4 configurable serial ports, exactly the same as the MOD-COM4 product.

Ports

The card has two 6-pin connectors, the top row and bottom row.
Each row can be configured as either:

  • 2 x RS232 without flow control
  • 1 x RS232 with flow control
  • 1 x RS485 half-duplex
  • 1 x RS485/422 full-duplex

Note that when using any RS232 mode in combination with RS485 or RS422 (any duplex type), the RS232 must be on ports 3 and/or 4 (bottom row).
RS232 can never be in ports 1 or 2 (top row) when using alongside RS485 or RS422 (bottom row).

For more details on the configuration options, please see the MOD-COM4 CFLink documentation which is the same for the CARD-COM4.
