Figure 1-2 shows the jumpers used to control the power source, and the optical
transceiver used.
Jumper JP2 connects to the boards two power planes. The MCP2150 Developer’s
Board has a power plane for the PIC18F65J50 and the related circuitry, and a second
power plane for all other circuitry. Removing the jumper allows the MCP2150 portion to
operate through the full voltage range of the MCP2150 (2.0V to 5.5V). When JP2 is
connected, then the maximum voltage is restricted to the maximum voltage of the
PIC18F65J50 device (3.6V). See Figure A.8 for the power plane layout. When JP2 is
open, then the PIC18F65J50 must be isolated from the MCP2150. This is done with
the JMP1:JMP14 jumpers as well as the R26, R27, R28, and R29 resistors.
Jumpers JP1C1 and JP2C1 are used to connect the default installed optical transceiver
to the MCP2150’s RXPD and TXIR pins. There are footprints for two other optical
transceiver implementations. If either of those implementations are installed, then the
jumpers may be switched to the desired optical transceiver.
