Connected to Switch

The user-supplied cable is installed as follows:

1.Connect the wire from Pin 8 of the cable to the switched side of the Screen Blanking Box or to a user-sup- plied switch.

2.Connect the wire from Pin 7 of the cable to the unswitched side of the Screen Blanking Box or to a user- supplied switch.

3.Connect the D9 serial connector to either COM1 or COM2 serial port on the Thor VM1 Quick Mount Smart Dock.

These two terminals are for connecting a serial cable:

 

 

• If using an optional Honeywell screen blanking cable, VM1080CABLE, connect the

 

 

gray wire to the switched side of the connection and connect the black wire to the

 

 

unswitched side.

Unswitched Switched

• If using a user-supplied cable, the cable must be constructed so that Pin 7 (RTS)

 

 

connects to switched side of the connection and Pin 8 (CTS) connects to the

 

 

unswitched side.

 

 

 

It is assumed that the motion sensing circuitry in the illustrations below is powered by internal vehicle circuitry.

Please refer to the appropriate illustration below for Screen Blanking Box wiring diagrams.

!CAUTION - Do not exceed the maximum input voltage, either 60 or 72VDC, specified on the Screen Blanking Box label when using this configuration.
