Appendix C: RS-232 Option
You may order the ACM/Flex16 external module with RS-232
Serial Line Interface Modules (SLIM). The RS-232 SLIM offers
the following features:
Each SLIM controls four ports.
LEDs on the ACM/Flex16 indicate the electrical interface in
use for specific groups of four ports.
SLIMS are field upgradeable, providing you with more
flexibility for your application.
Please refer to Figure 14 for a partial schematic of the RS-232
SLIM.

Note: The RS-232 Serial Line Interface Module controls four
ports, and therefore the schematic shows only a portion of the
circuit.
