2.3.1.1 Selecting UART Source and Optical Transceiver
Interface
Figure 2.2 shows two pairs of jumpers used to route signals to and from the
MCP2120.
Jumpers J1 and J4 are used to determine the source of the signals used by
the UART interface. When the header has the pins closest to the “DB9” label
jumpered to the center pin, the DB9 is the source of the UART signal. When
the header has the pins closest to the “Header” label jumpered to the center
pin, the four-pin header is the source of the UART signal.
Jumpers J6 and J7 are used to determine the source and destination of the
infrared data signals used by the interface between the MCP2120 and Optical
Transceiver. When the header has the pins closest to the “Integrated
Transceiver” label jumpered to the center pin, the integrated transceiver is
used. When the header has the pins closest to the “Component Transceiver”
label jumpered to the center pin, the component transceiver logic is used.

2.3.1.3 UART Mode
Figure 2.4 shows the jumper which determines if the MCP2120 Developer’s
Board is to be used in Hardware Baud operation, or Software Baud operation.
When in Software Baud operation, an additional signal is required, Request
To Send (RTS), which is used to drive the RESET
pin low to cause a change
of baud rate to occur.

2.3.1.4 Disabling the MCP2120
Figure 2.5 shows the jumper, JP4, which will enable or disable the MCP2120
device. When the MCP2120 is disabled, the device will consume less current.
Figure 2.5: MCP2120 Enable/Disable
In most cases, this jumper will be open. It may be closed to test system
operation when the MCP2120 is disabled. The Host Controller board may
control the operation of the MCP2120 by connecting a signal to the JP4
header as shown in Figure 2.6.

2.3.2.1 Selecting UART Source and Optical Transceiver
Interface
Figure 2.8 shows two sets of jumpers used to route signals to and from the
MCP2150.
Jumpers J2, J3 and J4 are used to determine the source of the signals used
by the UART interface. When the header has the pins closest to the “DB9”
label jumpered to the center pin, the DB9 is the source of the UART signal.
When the header has the pins closest to the “Header” label jumpered to the
center pin, the four-pin header is the source of the UART signal.
Jumpers J7 and J8 are used to determine the source and destination of the
IrDA signals used by the interface between the MCP2150 and Optical
Transceiver. When the header has the pins closest to the “Integrated
Transceiver” label jumpered to the center pin, the integrated transceiver is
used. When the header has the pins closest to the “Component Transceiver”
label jumpered to the center pin, the component transceiver logic is used.

2.3.2.2 Selecting Baud Rate
Figure 2.9 shows the two Baud Rate Select jumpers (JP2:JP1) and the baud
rate. Table 2.2 shows the baud rates for some crystal frequencies.

2.3.2.3 Disabling the MCP2150
Figure 2.10 shows the jumper (JP3) which will enable or disable the
MCP2150 device. When the MCP2150 is disabled, the device will consume
less current.
Figure 2.10: MCP2150 Enable/Disable
In most cases, this jumper will be open. It may be closed to test system
operation when the MCP2150 is disabled. The Host Controller board may
control the operation of the MCP2150 by connecting a signal to the JP3
header as shown in Figure 2.11.
