11.1 MPA-200 and EIA-530 Compatibility
If the MPA-200 is to be connected with an EIA-530 device, it may be necessary to swap the +/- conductors on the TXD and RXD signals.
11.2 Null-Modem Cables
The MPA-200 does not use a standard asynchronous PC serial port connector pin out. Typical off-the-shelf null-modem cables cannot be used with this card.
