RB-Bus (of FORMAC Plus) can be used instead of RA-Bus. The TXPAR line should be grounded and the RXPAR line left unconnected since FORMAC Plus does not generate a parity bit for X-Bus. Therefore, the software must mask out the interrupt generated from PLC-S due to parity error. The SUPERNET 2 Family for FOD! 1994 Data Book A-1al AMD Figure A-2.
