REAL-TIME PRINTOUT

A-2
The pin layouts are illustrated in Figure A-1. The conductive shell is used as
earth ground. An AMP connector is used to connect to the serial port. Use AMP
connector (AMP p/n 747538-1), ferrule (AMP p/n 1-747579-2) and compatible
pins (AMP p/n 66570-2).

Figure A-1: Serial Port Pin Layout

The serial cable must be shielded. Connectors at both ends of the serial cable
must have the shield terminated to the full 360 degrees of the connector's metal
shell. If rough handling or sharp bends in the cable is anticipated, use a braided
shield.
When a real-time printout is being received, a new line of data is printed every 2
seconds. Every 25th line will be a column heading line. A column heading line
will also be printed any time a value in the column heading line is changed. A
real-time printout is shown below in Figure A-2
