FAQs For CP-ITV Panels


Q: Can I mix different camera types on an ITV Controller?

A: If the cameras are from the same manufacturer and support the same communication protocol (EX: EVI-D70 and BRC) then yes. You cannot combine Canon and Sony cameras on the same controller.

Q: How do I change the output from RS232 to RS422?

A: The CP-ITV-D300 controller is an RS232 device only. To convert to RS422, you will need a RS232/422 converter which is available separately. Please be aware that if you are running Daisy chain, you will need only one converter. Home-run installations will require a converter for each channel in use.

Q: My controller doesn’t see my camera.

A: If this is a new install, verify that the camera is set up correctly for 9600 bps, and (if necessary, set for D30 emulation) Make sure that the camera is turned on and ready before plugging in the controller.

If this unit was previously working, try moving it to a different com port. If you are on port 1 or 2, use port 3 or 4 to test. This test will only work in home-run mode, so you may need to change operating modes to try this. See instructions below.

Q: I have more than one camera, but only camera 1 works.

A: Depending how your system is set up (Home Run or Daisy Chain), you may need to change the operating mode.

To change the mode, simultaneously press preset buttons 1, 2, 3, & 4. Hold them until they light. If Camera button 1 blinks, the unit is in daisy chain mode. If Camera button 2 blinks, the unit is in homerun mode.

Press Camera button 1 or 2 to change or confirm the desired mode. Button will light for approximately 1 second then all LED’s will extinguish. The unit is now ready to operate.

Q: My controller doesn’t keep presets when I turn off the power.

A: Preset positions are stored in the camera head, not in the control panel. Most do not hold their memory when power is turned off. Please check the user manual for your camera.

Q: What video switchers can I use with an ITV Controller?

A: Only the Kramer/Comprehensive CVG-SW61CS is supported for this controller.

Q: My Switcher and/or remote panel aren’t working.

A: When being used with a switcher and/or remote panel, the ports are used as follows:

  1. Camera connection – Daisy Chain only

  2. No connection

  3. Video Switcher

  4. Remote control connection – Requires null modem cable

Q: Can I put cameras on my remote controller?

A: Yes, configured as above. Either panel can have remote access to the cameras on the other panel, but not at the same time. You can switch between the local and remote cameras by pressing the Loc/Rem button on the controller.

Q: What is the maximum cable length for communications?

A: According to the Specification, baud rate affects the distance according to the chart below –

Baud Rate Maximum cable length (ft)
RS232 cable length according to Texas Instruments
19200 50
9600 500
4800 1000
2400 3000



The maximum cable length is 50 feet, or the cable length equal to a capacitance of 2500 pF. This means that using a cable with low capacitance allows you to span longer distances without going beyond the limitations of the standard. If for example UTP CAT-5 cable is used with a typical capacitance of 17 pF/ft, the maximum allowed cable length is 147 feet.

However, this is under “ideal” conditions. In practice, many factors may combine to significantly reduce the maximum distance.

Q: My controller won’t power up.

A: The connector at the controller end is removable, and it’s possible that the power supply is set for the wrong polarity. If you remove the tip and replace it so that the “+” symbol lines up with the word “TIP” it may correct your problem.

If the problem continues; measure the output of the power supply with a volt meter, it should read about 9VDC. If the voltage is correct, the unit will have to be returned for repair. Please contact Telemetrics for a return authorization.

Q: How do I adjust joystick sensitivity?

A: PAN_TILT_ZOOM Joy Stick Response Setting. There are two modes of operation; AUTO SPEED and SPEED SELECTION (default). The AUTO SPEED function will automatically vary the speed of pan/tilt joystick based on the current zoom position, with tighter zooms the joystick speeds will be slower allowing for more precise control.

The SPEED SELECTION function setting has 8 steps of joy stick response magnitude to affect pan and tilt speeds.

To display the Joy Stick Response Setting; simultaneously press the SPEED Fast (FT) or Slow (SW) buttons momentarily, upon release of the buttons observe the camera and preset LEDs. The LEDs will flash once displaying a code. In AUTO SPEED mode all the LEDs will flash, while in SPEED SELECTION mode only the one LED will flash, the eight LED positions correspond to the eight speeds (CAM1) is slowest speed and (PRESET 4) is fastest speed.

To change the Joy Stick Response Setting operation; simultaneously press the SPEED Fast (FT) and Slow (SW) buttons and hold until you see the camera and preset LEDs flash (approximately 3 seconds); this places the unit in AUTO SPEED mode. When in AUTO SPEED mode, when selecting a camera or discontinuing the use of the joystick zoom control the AUTO SPEED value will flash on its indicated LED. By pressing either the SPEED Fast(FT) button or SPEED Slow (SW) button will automatically switch to SPEED SELECTION mode and display the current value. Each time you press a button: SPEED Fast (FT) the speed will increment or SPEED Slow (SW) the speed will decrement.

While in SPEED SELECTION mode of operation: to set the SPEED SELECTION press the SPEED Fast (FT) and Slow (SW) buttons while viewing the camera and preset LEDs, the eight speeds correspond to the eight LED positions. Move the joystick to test the new response. Values are stored in permanent memory.
