4.5 COM Port Comparison

The I-7188XC(D) COM ports are as follows:

COM Port

Hardware

COM1

80188’s on-chip UART-0, 5-wire RS-232 or 2-wire
RS-485

COM2

80188’s on-chip UART-1, 2-wire RS-485

The I-7188XC(D) COM Ports can be set as RS-232 or RS-485 as
below:

COM Port Type Pin name

2-wire RS-485

Data+, Data-

3-wire RS-232

TXD, RXD, GND

5-wire RS-232

TXD, RXD, GND, RTS, CTS

The programming required for the 80188 UART is very different from
the 16C550. Interrupt handling on the 80188 is also very different from
the 8259 on a PC. Therefore, the RS-232 application programs for PC
are not executed in the I-7188XC(D).

The software driver for the I-7188XC(D) is an interrupt driven library that
provides a 1K QUEUE buffer for each COM Port. The software is well
designed and easy to use.

The software driver provides the same interface for all two COM Ports,
so each port can be used in the same way without any difficulty.
