Installation/Wiring 3-7
3.2.6 Serial port connection
Port “D", on the rear panel (see Figure 3–1), provides a serial data output for use
with external devices. The default Communication’s Protocol is 9600 baud, 1 start
bit, 8 data bits, 1 stop bit, and No parity. Figure 3–3 shows the serial
interconnections between the tester and a serial printer using 9 and 25-way D Type
connectors and to a PC using a 9-way connector.
The output format is controlled by the serial parameter in the set up menu.

3.2.7 I/O Connector E
The I/O control connector is a 25-pin female D type connector for connecting to
the optional remote unit, or any other external device requiring access to the
Program selection, Start and Reset inputs, and/or the Pass, Reject, End of cycle,
Ready, and Alarm outputs.
The I/O connector is designed to interface with the optional 690210 Remote
control unit and provides access to the following functions:
• Program selection.
• Start & Reset control.
• Pass & Reject outputs.
• Ready, Alarm, & End of cycle outputs.
In many cases, the I/O Control functions are sufficient for additional control of
both manual and automatic test rigs. thereby reducing the need for a PLC.
See Table 3–4.
