Jumpers
Jumpers are used to allow the Developer’s Board to be configured into the
different modes that are possible. These modes include:
Selection of Baud Rate
Source of Host signals
Source of Optical Transceiver signals
Device Enable signal for power down operation
A.4.1
MCP2120 Developer’s Board
The MCP2120 Developer’s Board has the following jumpers:
1.
Two jumpers to select source of UART signals. Either RS-232C socket
or the four-pin header.
Three jumpers to select desired baud rate.
Two jumpers to select IR Transceiver options.
Jumper to disable device operation.
Jumper for Software Baud control when using RS-232C interface.
