Guest Zark Posted October 25, 2005 Share Posted October 25, 2005 I manage a sleep lab in the United States. We have several Sony SSC-E473 SuperExwave color cameras that work OK except that I need them to switch to night mode at higher light levels (dim incandescent) than their programming will allow. I am using IR lights. The cameras are being used to record medical procedures. The manufacturer's instruction sheet is unclear, at least to me, on how to hook up the external day/night trigger control. Here is what it says: Pin #1: External Control Output. Outputs the color/B&W switching signal. Pin #2: COM. Ground for External Control In/Out. Pin #3: External Control Input. (Accepts high impedance signal only.) When H (+5V) is applied between this terminal and COM, color mode is selected. When L (0V) is applied, B&W is selected. Have any of you used this camera or ones similar and hooked up the external trigger to switch between day/night modes? Any insight on how to get this working is much appreciated.

Rich Posted October 25, 2005 Share Posted October 25, 2005 Hi Zark What are you using for the Day/Night trigger? You need to know the 3 conections of the day night trigger you are using. Basically, it sounds like your external trigger will supply 0 volts between pins 2 and 3 for B&W operation, then it will supply +5 volts to switch the camera to colour mode. Pin 1 sounds like its the signal telling the external trigger what state the camera is currently in. Do you have information on the external trigger?
