Sub-Channel Activity Controlled by Interface Lead (C/I)
If the system application requires one or more of the default settings to be changed, it will be
necessary to remove the top cover of the enclosure to access and change the DIP switches
located on the printed circuit board.
Disassembly
Remove the top cover by removing the phillips head screws located on the left and right sides
of the 3060/X21 (CTS MD-X.21/TCB). DTE/DCE switches SW7 through SW20, interface
Jumpers J1 and J2 and configuration switches SW21 through SW27 are located on the PCB
as indicated on the strapping guide in the Appendix of this manual. After the switch selection
activity is completed,
reinstall the top cover BEFORE connecting to a AC power source.
Installation
Select an appropriate location accessible to and within six feet of an AC power outlet. The
outlet must have a ground pin receptacle for product warranty. The DCE-to-DTE cabling
between each attached device and the 3060/X21 (CTS MD-X.21/TCB) should be “Straight
Through”, shielded and terminated with male connectors. Sub-Channels are marked PORT 1
through PORT 6. The Master Port is marked, MASTER DCE/DTE. If any terminal has a priority
service mode, ensure it is connected to the port connector designated “PORT 1” on the
rear panel of the 3060/X21 (CTS MD-X.21/TCB). Secure the other Terminals or Modems to
be serviced to the remaining “PORT” connectors. Connect the Modem or Terminal to the
connector designated “MASTER”.
