MCP2120
RXIR
pin
Yes
No
Data
appear on
MCP2120
RX pin
Yes
No
Verify that the connection for
Board #1 TXIR to Optical
Transceiver and Board #2
Optical Transceiver to RXIR
(3 pin headers J6 and J7).
Ensure that the Optical
Transceivers are aligned.
Ensure that distance between
Board #1 and Board #2 is
approximately 6” (15 cm).
Try component transceiver
option on each board
(Board #1, then Board #2,
and lastly both boards)

MAX232
T1OUT
pin
Yes
No
Verify 3 pin header J4
is jumpered correctly
Disconnect serial cable
to ensure T1OUT is
not loaded down. If
that the MAX232 device
is damaged
Verify that the connection from
PC #1 to Board #1 is good.
Try communication with
another serial device
(such as PICSTART Plus).
Problem with MCP2120
Verify device has power/ground
Ensure jumper JP4 is open
Ensure crystal oscillator is correct
frequency and operating
Ensure Baud Rate is correct
(jumpers JP1, JP2, and JP3)
Try replacing with new MCP2120
still no data, it appears
