50m cable! Hm... Wouldn't it be better to put the gmc where the detector is, or is would it be like, destroyed by neutron radiation or something?
It's not HD video over hdmi cable, but 50m is pretty far nonetheless. Hm. I'm sure it's not possible to use a simple cable. You probably need some kind of signal amplification. I'm sure you could use an audio amplifier.
The best way is to use 50m signal data cable instead of the tube cable . Let the GMC unit with the tube together. The only thing you need is to make sure the GMC unit is safe in full weather condition.The data signal is much stable than tube signal.
What is your question then? The counter can show a maximum of 65535 counts per minute. However, it can accurately count beyond that but I don't know how that looks in the data. I think I'll test this later today. You can manipulate the data to give you 10 second segments. You don't need to reprogram the device for that. I'm not sure if you can start and stop counting by console commands. But you can remotely start gathering data in a file. With a PC connection.
