2.2.10 Packet Serial Wiring

In packet serial mode the MCP can transmit and receive serial data. A microcontroller with a

UART is recommended. The UART will buffer the data received from controller. When a request

for data is made to the MCP the return data will have at least a 1ms delay after the command

is received if the baudrate is set at or below 38400. This will allow slower processors and

processors without UARTs to communicate with the controller.

The diagram below shows the main battery as the only power source. Make sure the LB jumper

is set correctly. The 5VDC shown connected is only required if your MCU needs a power source.

This is the BEC feature of the MCP. If the MCU has its own power source do not connect the

5VDC.
