Appendix A
Module Adapters - DA-191B
The DA-191B Data Module can be installed with one of two optional module adapters,
depending on the data interface desired. These are:
•
MA-404
- RS-232C, with provision for CTS, TXD, RXD, CD
•
MA-418
- RS-449/422, with provision for SD-A, SD-B, RD-A, RD-B
Both of these module adapters provide RJ-11 connectors for the data ports. Active ports are
numbers 1 through
n
, where n is the number of active data channels. Thus, for single channel
operation, use the CH. 1 port; for two channels, use the CH. 1 and CH. 2 ports; and so on.
To install either of these Module Adapters:
Insert the MA into the rear of the slot that will
hold the DA-191B module, secure it with the screws provided, and connect the RJ-11 lines.
The following sections define the pin assignments for these MAs.
