Response System Setup

The CPS receiver unit plugs into one serial (or communication) port on the back of the personal computer (PC) running the CPS software and into a standard AC power outlet. Most computers have 2 serial ports; some have more or less. Occasionally, a mouse or other navigational accessory already occupies one of the ports. If that is the case, use the second port.

Select COM Port

To make certain that the serial port you plugged into is the same as the one from which the CPS software is recording, do this:

1. Connect the receiver unit (or hub) to a serial port (9-pin COM port) on the back of your computer. (If you have a USB port instead, contact eInstruction about purchasing a USB-Serial port adaptor).

2. Start CPS.

3. Click the Settings menu item and select Delivery Options.

4. Click the Detect CPS Receiver button.

5. CPS automatically searches to find the receiver unit on an available com port.

CPS Auto Detects which COM Port is Available and begins using it

If a receiver unit is not found using the automatic search, the system will provide a manual wizard for finding the CPS receiver unit(s). You will be positioned back to com 1 and asked to respond with a CPS response pad. (see image below) If CPS detects a vote from the CPS response pad, CPS will tell you it found the receiver unit(s). If not, you will need to select the “Next” button to move to the next available com port and again press any button on a CPS response pad. You will do this for each com port until the receiver unit is found. If you are routed through all available com ports without CPS detecting it you will need to call our tech support department at 888 707-6819.

The first time you deliver questions and the pads respond, the receiver unit communicates to the COM port. If you deliver questions and the receiver unit does not seem to be receiving responses from the pads, see Troubleshooting the Response System for some ideas.
