Technical Data CP9035
Description of the Status LEDs
LED 100 - 12V supply voltage present
If the LED is illuminated, the 12V supply voltage for the Control Panel is
present at the lower BNC socket (CP-Link B). If it is not lit there may be a
short circuit, or the PC power supply unit may not be operating correctly.
LED 101 - Transmit PLL locked
If the LED is lit, the clock signal from the video card is present. If it is not lit,
then either the video card is not operating correctly, or the connection of the
video card to the CP9030 is not made properly.
LED 102 - Receive PLL locked
If the LED is lit, data are being sent from the Control Panel to the PC. If it is
not lit, the most probable reason is that the upper coaxial cable (CP-Link A)
is defective or is not properly connected.
LED 103 - Receive data error
If the LED lights up, receive errors are occurring.
This LED is lit continuously if there is no connection to the Control Panel.
LED 104 - Not used
LED 500 - CP-Link RUN
This LED flashes for a short period when the computer is switched on, and
then becomes continuously lit. When the LED is lit, the communication
software on the CP-Link has started running.
LED 501 - CP-Link COMM-ERR
If the LED flashes, data errors are occurring. A single flash when the screen
mode is changed is normal. Transmission is then resynchronised. If the
LED continues flashing, then either the coaxial cable is damaged, or there is
excessive interference from other devices such as frequency converters,
large transformers, etc.. This may be remedied through the use of high-
quality double-screened coaxial cable.
