RJ Adapters & Cables (for CPM/MDS Units)

There are several Western Telematic units which use RJ-12 interfaceconnections (same size as RJ-11 jacks, but with 6-conductor cable). TheRJ interface allows for inexpensive modular cable runs, and also allowsmost WTI units to occupy only a single rack unit (1.75" High x 17"Wide)

WTI Units which use the RJ-12 Interface:

CPM-400 4-Port Remote Site Control Port Manager
CPM-800 8-Port Remote Site Control Port Manager
CPM-1600 16-Port remote Site Control Port Manager
CPM-6400 8 to 64-Port Remote Site Manger &Data Matrix Switch
MDS-8 8-port any-to-any data matrix switch
MDS-16 16-port any-to-any data matrix switch

The following adapters with part numbers SA-NN are DB-9 or DB-25 toRJ adapters. They allow the user to convert their standard DTE or DCE portsto the RJ interface, then use standard 6-conductor RJ cable between theadapter and the RJ port on the WTI unit. Adapter part numbers include Mor F indicating the gender on the SA-NN adapter itself. For example, toconnect from a DB-9M Standard PC COM port, you would require an SA-9F adapter.
