Figure 5. Video Cable Wiring Configuration
The three coax shields are soldered together and a
stranded AWG #16 (1.3 mm
2)
wire of less than three
inches is soldered to the connector shell and to the
shields. The shields are also tied to pin 1 of the con-
nector.
Configuration
There are no user DIP switches or jumpers on this
board for configuration. However, the IC640HWP77X
software must be loaded using PCM Development
Software (refer to the Graphics Display System User’s
Manual for details). The GDC must be configured with
IC641 Configuration software prior to use.
Status Indication
Three Status LEDs are available as shown in figure 2.
The top LED indicates the condition of the GDC mod-
ule, the bottom two LEDs indicate serial port and
backplane activity.
Controls
One pushbutton is provided on the module. Push
and hold for less than 5 seconds will restart an ap-
plication. Push and hold for more than 10 seconds
and the module factory default configuration will be
installed (this action will not clear memory but will
permit communication with the programmer using
factory default settings).
Batteries
A lithium battery (IC697ACC701) is installed as shown
in figure 2. This battery maintains user memory
when power is removed. Be sure to install the new
battery in the unused battery connector before re-
moving and discarding the old battery. If during
power-up diagnostics a low battery is detected, the
Module OK LED (top) will not stay on.
