5. Truck Cab Computer Installation
5.1 GENERAL REQUIREMENTS
A minimal truck cab computer system
includes:
1. A supervisory control module (SCM)
that is mounted between two right
angle brackets
2. A dot matrix ticket printer
3. A Lap Pad (key pad/display).
Systems equipped with the RAM card
option will have a RAM interface module
mounted atop the supervisory control
module. Dual meter systems will have a
Dual Meter Switch mounted below the
SCM. (See Figure to the right)
The truck computers are shipped with
the components and brackets
assembled. The installer has to bolt the
brackets to the cab floor, ground the
SCM to the truck electrical system, and
route the power and signal cables to the
appropriate connectors on the SCM and
Dual Meter Switch.
The printer also needs to be mounted in
the truck cab, usually on top of the SCM
“stack”. The Lap Pad is secured in a
holder on the side of one of the
brackets.
