3.4 Connecting the Model 1450 I/O Expansion Module
Like the 1350 Breakout Module and the Model 1460 I/O Expansion Module, the optional
Model 1450 I/O Expansion Module (P/N 800-5758-1/800-5758-1R) provides convenient
access to the sensor’s power, serial communications and discrete I/O lines. In addition to the
two discrete outputs, acquisition trigger, and serial transmit/receive that are standard on the
sensor, the I/O Expansion module provides the following:
• 8 discrete outputs
• 8 discrete inputs
• RS-232 hardware handshaking

To Connect a Model 1450 I/O Expansion Module to the In-Sight Sensor:
1. Verify the 24VDC power supply being used is switched off.
2. Optionally, connect the power and ground wires for the acquisition trigger input, discrete
outputs, and discrete inputs to their corresponding terminals on the Expansion Module.
3. Optionally, connect the DB9 male connector of an RS-232 serial cable to the corresponding
DB9 female connector on the Expansion Module.
4. Plug the I/O Module Cable’s DB15 male connector into the corresponding female connector
on the Expansion Module.
NOTE:
The outputs labeled HSOUT 0 and HSOUT 1 are high-speed outputs direct from the sensor
and pass through the Expansion Module. The outputs labeled OUT 0 through OUT 7 are
lower speed because the Expansion Module processes these signals before being sent to
remote devices.
