In a 1:1 PC Link, a CPM1/CPM1A is linked to another CPM1/CPM1A, CPM2A/
CPM2C, CQM1, C200HX/HG/HE, or C200HS PC through an RS-232C Adapter
and standard RS-232C cable. One of the PCs will serve as the Master and the
other as the Slave. The 1:1 PC Link can connect up to 256 bits (LR 0000 to LR
1515) in the two PCs.
