Jumpers
ID Label Purpose Part #
J1 120 Ohm The jumper turns on (once installed) a 120 Ohm
terminal resistance required by the CAN bus. Install the
jumper on one of the controllers in a CAN network.
Sullins Connector Solutions SPN02SYBN-RC
J2 Boot The jumper (once installed) switches the controller into
a firmware re-flashing mode. Do not forget to remove
the jumper after finishing the re-flashing procedure!

LEDs
ID Label Purpose
H1 POWER This LED is directly wired to power supply lines. The LED turns on whenever a power supply is connected to
“+” and “-” terminals of the controller.
H2 FAULT This LED turns on whenever firmware detects a fault or multiple simultaneous faults. A telemetry parameter
“Fault Bits” tells what faults have caused the problem. Note that the firmware latches into a FAULT mode before
turning the LED on. In this mode, the motor is de-energized and the firmware stops responding to any command
rather than the RESET command. Send a RESET command to the controller in order to clear the fault latches
and switch the controller back into an operational mode once the fault is rectified.
H3 LED1 The LED turns on whenever the controller receives a command from a parent control system via either CAN or
USB. The LED indicates that a parent control system is successfully communicating to the controller.
H4 LED2 Not used (firmware-specific)
First pin & Soldering Holes
First pin of every connector is labeled with a “1” sign.
The controllers come with soldering holes for every signal or power line. The soldering holes allow cables to be
soldered directly to the boards from either side to form vibration-resistant connections. Use a multimeter to match
pins vs. soldering holes (“buzz the circuit”).
