DMXPathfinder LR Installation & Assembly

M ODULE P REPARATION
Unpack all of the DMXPathfinder MR system modules and accessories and
arrange on a flat surface. First, locate the package of screws supplied with
each module, and use 8-32 screws to attach the rack mount ears to the sides
of each Input and Output Module.
If P2020 type termination boards are to be used, mate them to each Output
Module and fasten with 5 x 6-32 screws.
Using one power cord, power up each Input and Output Module one at a time
and verify that the main power LEDs illuminate.
Remove the four adhesive rubber feet from the bottom of each module.

NSTALLATION
Starting with the last (bottom) Output Module, install the modules into the
equipment rack. Normally the Input Module is located above the Output
Modules, but it can be placed at the bottom, if desired. In any case the Input
Module may not be placed between Output Modules.
Locate the 37-conductor ribbon cable jumpers and 37-pin bus terminator(s).
There should be one 8” long cable for the Input Module and one 4” short
cable per Output Module.
Attach the long jumper cable from the Input Module to the top Inter-Module
Bus connector marked “CABLE A IN”. Install the short ribbon cable jumpers
between Output Modules. The bottom connector marked CABLE A THRU on
one module connects to the top (IN) connector on the next lower module in
all cases.
Install the 37-pin bus terminator plug at the bottom or last unconnected
CABLE A THRU jacks in the system.
It is unnecessary to connect anything to the CABLE B jacks on the Output
Modules, however if additional jumper cables have been supplied it’s a good
idea to install them there for possible future upgrades.
