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 | DESCRIPTION |
| EIA-422 | | |
| | | |
1 | TX+ | Output | Transmit Data (+) |
| | | |
2 | TX- | Output | Transmit Data (-) |
| | | |
3 | RX- | Input | Receive Data (-) |
| | | |
4 | RX+ | Input | Receive Data (+) |
| | | |
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
10below.
M24SII-V07 Port | Equipment |
(EIA-422, 4-wire, bidirectional) | Connections |
RJ-11 | RJ-11 |
1 | TX+ | RX+ | |
2 | TX- | RX- | |
3 | RX- | TX- | |
4 | RX+ | TX+ | |
