The DB-201 driver board uses H-bridge outputs. They are
typically in a pair, but you can use two individual outputs
on each pair. The off state for the DB-201 outputs are
ground.
The DB-201 driver board controls/monitors the following
devices/functions, but are not limited to:
• Lights
• Locks
• Slide-outs
• Generator
• Parking brake
• Ignition
2.3.4 LR-125 Wi-Fi Server Module
5 LR-125 Wi-Fi Server Module
The LR-125 is the onboard Wi-Fi server. It must be
connected to the main power supply and the RVC
network bus as outlined in the schematics.
The changes from the 3.5 in. (89 mm) displays are
updated to and from the LR-125 application. The time on
the clock screen updates based on the LR-125
communication through the RVC network.
2.3.5 TM-502A Inverter Interface
6 TM-502A Inverter Interface
The TM-502A inverter interface is used for a Magnum
inverter (MMS1012) that is not RVC compatible.
2.3.6 TM-2021 HVAC Load Box
7 TM-2021 HVAC Load Box
The TM-2021 load box is the interface module that
controls the HVAC appliances.
The TM-2021 controls/monitors the following devices/
functions:
• Temperature sensor
• Battery
• Pump
• Fans
• Furnace
• AC
