User Manual

Jumper and Switch Settings

This section presents multiple settings for the MCU Modules’ jumpers and switches.

BUS

Control Select Jumper

Under standard conditions, the V

BUS

Control Select jumper should be in the ON position

(1-2) to force the ENABLE signal High and cause the V

BUS

relay on the MultiMotor

Series Development Board to turn ON, thereby supplying bus voltage to the MOSFETs. If

the jumper is in the MCU position (2-3), the ENABLE signal will be controlled by a GPIO

from the MCU, as indicated in Table 7.

Table 8 shows which GPIO controls this ENABLE signal, depending on the MCU Module

being used. Using this ENABLE signal from the MCU serves to meet IEC 60730 Class B

compliance requirements because the bus voltage can be turned off almost immediately if

an error is detected.

UART Flash Select Jumper

Due to pin limitations on some MCUs, the UART Flash Select jumper selects between

access to the UART or to SPI memory, as indicated in Table 9.
