Range, Filter, and

Channel 1, 2

Connect Register

Each channel has an 8-bit byte that controls the input signal range, filter cutoff and the relay that connects the channel to the front panel connector. The fastest way to change range, filter or the connect relay is to write a 32-bit word to the register. After every write to this register the bus is held off 10 ms until the range, filter and relay information is sent to the isolated channel. The settling time for the relays, filters and the gain amplifier is about 20 ms. This register controls channels 1 and 2. :
