LOCAL CONTROL INTERFACE
When the RFL DS-TT is installed in an IMUX 2000 multiplexer, it can be operated under local or
remote control. When under local control, the module setup parameters can only be programmed
using the DS-TT local RS-232 port. The RS-232 port is labeled J1 and is located near the front of
the DS-TT module as shown in Figure 1. Connections are made using the cable shown in Figure 2.
Then use the SCL commands as described in the Remote Control Interface section of this
instruction data sheet.
NOTE
Local mode requires transfer trip modules with software version SW2000TT008
or higher and CM3R Rev H or higher.
When settings are changed, the alarm LED “DS9” illuminates while the settings are being written
to the EEROM. The card should not be removed until after the LED goes OFF.
