RS-232 COM0 and COM1 Pin Connections
The G4LC32ISA-LT has two built-in serial ports. For RS-232 communication, jumpers must be
installed on B0 through B8 for COM0, or C0 through C8 for COM1. The following table contains
descriptions for each pin.
Important: If RTS and CTS are not used, they should be disabled (default) and not enabled by software.
Remember to install the port’s RS-232 communication jumpers. See Figure-3-3.
