Identity Code
The CNTV identity code (ID CODE) consists of a two-digit hexadecimal number. These codes are vital for
proper communication and typically factory set. An ID CODE label is affixed to each unit. The ID CODE can
range from 03 to FE. The ID CODE of each unit must match the ID CODE specified in the SIMPL Windows
program in order for the device to be addressed properly.
If the CNTV ID CODE needs to be altered, it can be set from a PC via CNTV SETUP menus. Refer to the
Appendix in this guide for details that describe the method of setting the CNTV ID CODE.
Power and IR Testing
Power and IR testing consists of equipment placement and running a software test. Placement of sensing
devices must be performed before running the software test. Make proper connections as shown in figure
4. Refer to the Appendix in this guide for details that describe how to run a power sensor test. If a wired
panel is employed, an abridged power sensor test consists of observing illumination of the "POWER" LED
while turning TV power on and off manually.
Power Sensor Placement
Use a CNTV-CS (supplied) or power sensor loop (optional) to detect power from television or other
equipment to be controlled. The CNTV-CS should be plugged into an AC outlet and the television to be
current sensed is plugged into the CNTV-CS. The digital connector of the CNTV-CS is attached to the
DIGITAL IN/OUT back panel connector of the CNTV. Alternatively, a wire loop (as shown in figure 3) can
be constructed and placed in the electromagnetic field of the television flyback transformer. Perform
Power Sensor Test (refer to Enter Test Menu in the Appendix of this guide) to determine if the device is
OFF or ON or in the electromagnetic field.
NOTE
The loop is less reliable than the CNTV-CS, since it depends heavily on position and
the low-power emissions of the television.
