For instructions on mounting network devices, refer to the instructions included
with those products. For instructions on configuring the operation of the devices
connected through the Convergence Network ports, see the help menu in the
Convergence Network Configuration Software.
Expansion Module Relay Outputs
The Pathfinder Expansion Modules has a total of 18 solid-state relay outputs. See
Figure 2. Relays 1-16 are intended for flashing lights and can each provide up to
seven 0.5 A switched from the battery terminal. These relays can be programmed
to flash various patterns and dim levels.
Relays 17 and 18 are intended to control DC loads in the car and can be
programmed to turn them on and off through timers.
All of the relays (1-18) have a software-programmable current limit. By default, the
current limit setting is disabled.
See the Pathfinder Configuration Software for all available programming options
available for the Pathfinder relay outputs.

System Power
The EXPMOD-2 Expansion Module has a Power Stud to connect the B+ power
input. Included in the Expansion Module kit is a 6 mm, pan head, M4 SEMS Screw
and a #8 Insulated Ring Terminal. The power stud is designed to accept a 6 AWG
wire. If you use a different terminal, it should accept an M4 screw. Fusing of the
Expansion Module is required and left for the installer to complete. The fuse
must be of an amperage capacity sufficient to handle the electrical loads of the
Expansion Module.
Convergence Network Connections
The EXPMOD-2 has three ports on the side for FS Convergence Network.
