C. Locate the switching module where the component will be connected. Each
module has either 2-pin or 4-pin headers above the product connectors
numbered from 1-4, or 1-8 ( Figure 39 ). As you install the display products, you
will connect the PSBs to these headers using the cable assembly supplied with
each, being careful to observe proper polarity ( Figure 40 ).
3. Installing Remote Switches (980 System Module)
In systems without a control panel, it is often desirable to add
“outboard” switches for remote operation of certain system
management tools.
A. Remote Power Switch.
• If your system does not include a Control Panel,
you may want to turn the system on and off using
a remote key switch or toggle switch.
• Use any SPST (single-pole, single-throw) switch
you prefer. Low current switches will work
perfectly well.
• Connect the switch between the “Power” and
“Com” pins of the 980’s ”Remotes” terminal block.
B. Remote System Reset.
• There is a “System Reset” button on the 980
that enables the user to reset the system in
the unlikely event that the system “hangs up.”
Pressing this button will re-boot the entire system.
Having a Remote Reset switch is a good idea in
any system since the 980 is usually buried inside
the display and would not be readily accessible
if the system ever needed to be reset. You may
wish to “hide” this remote switch from
customer access.
• Connect a SPST switch ( Figure 42 ) between the “Reset” and “COM” pins on the “Remotes” terminal
block located on the 980 ( See Figure 41. )
• Your system can now be “Reset” using this remote switch.
Figure 40. Be careful to maintain
PSB cable polarity with keyed plugs.
