COM1 is a 9-pin (DB9), DOS-compatible, RS232C serial port,
with its own address. COM1 occupies two input/output
locations. The maximum supported data rate for serial channel
operation through any of these ports is programmable up to
115.2Kbaud. The serial controller tied to these ports conforms to
the UAR/T industry-standard PC16550 device architecture
(including 16-byte FIFOs) with fully independent baud rate
generation. Pin 9 (RI) can be factory-configured as a +5 VDC
supply for optional barcode scanner power.
COM2 is a 9-pin (DB9), DOS-compatible, serial port that can be
software-configured to support RS232C or RS422/RS485 proto-
cols. COM2 has its own address, and occupies two
input/output locations. The maximum supported data rate for
serial channel operation through any of these ports is program-
mable up to 115.2Kbaud. The serial controller tied to these ports
conforms to the UAR/T industry-standard PC16550 device
architecture (including 16-byte FIFOs) with fully independent
baud rate generation.
Software-configuration of the COM2 port protocol is accom-
plished by running the Setup Utility and specifying which
protocol is to be used.
