Connecting DSU/CSUs in a Daisy Chain
You can connect up to 60 Multi-port Encore DSU/CSUs in a single RS-232 multi-drop
(daisy-chain) for the purpose of monitoring and managing the DSU/CSUs from a
single centralized workstation.
Use a ribbon-type cable with DC-9 connectors (available from Digital Link).
To daisy-chain multiple systems together:
1. Connect the female connector of the ribbon cable to the terminal or
modem (if at a remote site).
2. Connect the male connector to the Comm Port on each DSU/CSU.

NOTE: CTS (pin 8) must be connected between the DSU/CSUs, and not connected to the
terminal. Refer to Appendix B, Connector Pin Assignments.
