Modular Service Tool

Wether you have a Stand Alone, Interconnected or Networked System,
the Modular Service Tool always connects to an HVAC unit controller
via a prefabricated cable that is supplied with the service tool. The Modu-
lar Service Tool cable is terminated on both ends with a mini DIN con-
nector. Attach one end to the Modular Service Tool and the other end to
the mini DIN connector on the HVAC unit controller. If this is an Inter-
connected System, all controllers that are interconnected with commu-

System Connections

nications cable can be programmed from any HVAC unit controller on
the loop. If this is a Networked System, all controllers on the entire
Networked System can be programmed from one HVAC unit control-
ler.

Be sure that the Modular Service Tool has fresh batteries installed or
that it is connected to a power source using the supplied power pack
before attempting any programming of the controller. See Figure 3 for
connection details.

Be Sure The Modular Service
Tool Is Connected To The
Supplied Power Pack Or Has
Fresh Batteries Installed Before
Attempting Programming Of The
Controller. Be Sure The Power Is
Turned Off On The Modular
Service Tool Before Connecting
The Cable To The Controller.

The Modular Service Tool Can Be Connected To Most
Controllers By Plugging One End Of The Supplied
Cable Into the Modular Service Tool DIN Connector
And The Other End Into The DIN Connector On The
Controllers.

Some Controllers Without DIN Connectors Require
Use Of The Supplied PL101904 Adapter Board Shown
Above. To Connect With Adapter Board, First Unplug
COMM Terminal Block From Controller Board. Plug
PL101904 Adapter Board Terminal End Into Terminal
Block Base On Controller. Plug DIN Connector Cable
Into DIN Connector On PL101904 Adapter Board . See
Optional Connection For Controllers Without DIN
Connector Above For Illustration Of This Connection.
