B.3.6 Switch-to-Modem, EIA-485 Null Modem Cable for CDM-Qx/QxL (DB-9MDB-9M)

You may use this cable as part of the Switch to CDM-Qx/QxL EIA-485 Multi-Drop daisy-chain. Connect one end of this cable to the Switch

CRS-230 System Controller “485 Pass-Through” connector, and the other end to one of the DB-9F connectors on either the standard

CA/WR11417-1 EIA-485 Multi-Drop Shielded Cable (Figure B-7) or the optional CA/RB11423-1 EIA-485 Multi-Drop Ribbon Cable (Figure

B-10) that interconnects the Modems.
