TEK-CPCI-1003 Technical Reference Manual
7-12
Upon a power-up or reset, the Serial Port 3 interface circuits are automatically configured for
the operation mode setup in the BIOS. The Serial Port 3 signal assignation on the J5 CPCI
I/O connector depends on the operation mode (RS-232, RS-422, or RS-485) it has been set:

To configure the Serial Port 3 operation mode, use the BIOS setup program. See Section
12.3.7 -
Integrated Peripherals
.
§
Infrared Mode:
Infrared (IR) interface signals are provided to drive IR module for remote operations
through Serial Port 3. When set in IR mode, the IR interface supports multi-protocol
infrared operations. The IR interface is IrDA 1.1 compliant, and supports TEMIC/HP
modules, SHARP ASK IR, and consumer IR.
§
RS-232 Protocol:
When configured for RS-232 operation mode, the Serial Port 3 is 100% compatible with
the IBM-AT serial port signals.
§
RS-422 Protocol:
The RS-422 protocol (Full Duplex) uses both RX and TX lines during a communication
session.
There are no user software restrictions except that software must not attempt to use the
handshake line because they are not connected. However, handshaking by software only
(XON-XOFF) may be used.
CAUTION
In RS-422 mode, W9 and W10 jumper caps must be installed to connect
the 120 ohms termination resistors (See Section 10 –
Jumper Settings
).
