4.3 Using the Download Port as a COM Port

The download port (COM4) of the I-7188XA(D) can be used as a
general purpose RS-232 port in the following manner:
Step 1: Download custom programs and autoexec.bat to I-7188XA(D)

first.

Step 2: Switch off the I-7188XA(D) and remove the download cable from

the Host PC.

Step 3: Disconnect the INT* pin from the GND pin of the I-7188XA(D) if

they are connected.

Step 4: Switch on the I-7188XA(D) (no standard input, no standard

output, no debug information).

Step 5: Connect a download cable between a new RS-232 device and

the COM4 of the I-7188XA(D).

Step 6: Initialize the COM4 to the new configuration.
Step 7: The COM4 of the I-7188XA(D) can now be used a general

purpose RS-232 port.
