Bidirectional Printer Sharing Mode - BayTech 24SII Owner's Manual

         
    
NOTE: Ports using this configuration will support XON/XOFF
handshaking only. You must enable XON/XOFF handshaking in
configuration mode for these ports (see Section 8.8.1 ) and on the
equipment that will connect to these ports.
Ports on the M24SII-V07 module using EIA-422 Protocol, 4-wire
Operation, and bidirectional Printer Sharing Mode use the following
pins and signals for communication:
RJ-11 PIN-OUT INFORMATION
PIN SIGNAL DIRECTION
EIA-422
1 TX+ Output
2 TX- Output
3 RX- Input
4 RX+ Input
When connecting an EIA-422 device to the M24SII-V07 module using
4-wire Operation and bidirectional Printer Sharing Mode, the cable
required to connect the two devices must have TX+ wired to RX+ (and
vice versa) and TX- wired to RX- (and vice versa). Please see Figure
10 below.
