emove fuse by pulling the “FUSE PULL” lever to the left.
Using a suitable tool, remove voltage selector PC board by pulling on the small
hole located on the edge of the board.
Select the voltage by positioning the PC board so the desired voltage is indicated
on the top left corner. Insert the board in place in this position.
Install the fuse and slide the plastic cover to the right. The selected voltage will
be visible through the plastic cover.
8.3.3 GROUND LUG
In particularly noisy environments the MDC-360 should be grounded to the
instrument rack, or other good ground, by means of the grounding lug in the rear
8.3.4 REMOTE WER HANDSET
Figure 8-1 show e location of the cle into which the Remote Power
Handset is plugged.
The system interface with the remote sensor oscillator is a 50 Ohm coax cable
terminated with BNC connectors similar to AMP 225395-1 (plug) and AMP
225396-1 (jack). The plug on the Source-Sensor Board mates to a jack on the
cable which is supplied with the oscillator.
The control voltage output is interfaced via a 4-pin, circular mini DIN connector
equivalent to CINCH MDSS-4S. The pin layout is defined in Figure 8-4 and
Table 8-2 supplies pin signal assignments.
8.3.6 RS-232 COMMUNICATION
There are two connections for the RS-232 interface port. A D9P connector is
provided on the rear panel for permanent connection to the host computer. The
pin layout is shown in Figure 8-5 and Table 8-3 lists pin signal assignments,
including a definition of whether the signal is an output from the MDC-360 or an
input to the MDC-360.
A DJ11 jack located on the front panel is provided for temporary connection to
the host computer. Pin layout and pin signal assignments are shown in Figure 8-7
and Table 8-5.
The MDC-360 acts as DTE, and accordingly the 9-pin connector has ‘plug’ pins.
It can be used with a DCE or a DTE host cable connection providing the sense of
the RxD/TxD data lines and the control lines is observed. Pin 2 ‘TxD’ transmits
