1-9-10 SRM1 One-to-one Link Communications
In a one-to-one link, a SRM1 is linked to another SRM1, CPM1/CPM1A, a
CQM1, or a C200HS 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
one-to-one link can connect up to 256 bits (LR 0000 to LR 1515) in the two
PCs.
One-to-one SRM1 Links The following diagram shows a one-to-one link between two SRM1s.
The words used for the one-to-one link are as shown below.
