F.8 DAISY CHAIN OPERATION Up to 8032’s may be ”daisy chained” together using a common RESET and CLOCK control line. This may be advantageous in situations where either there are not enough control ports available on the Micro-800/MICRO-1000 datalogger for the number of multiplexers desired, or to reduce the number of cables required to implement a large multichannel system. - Page 44 Micro-800/1000 Datalogger Reset Clock Reset Clock Multiplexer #1 MUX1 VW Gages 1-32 SW1 SETTING: OFF OFF OFF Reset Clock Multiplexer #2 VW Gages 33-64 MUX2 SW1 SETTING: OFF OFF ON Reset Clock Multiplexer #3 VW Gages 65-96 MUX3 SW1 SETTING: OFF ON OFF Daisy chain Configuration...

Page 45: Maximum 8032-5 (Tan Cable) Cable Lengths
F.9 MAXIMUM 8032-5 (TAN CABLE) CABLE LENGTHS The 8032 Multiplexer is a low power device, that when combined with a Micro-800 or Micro- 1000 Datalogger can be physically located at a considerable distance from that Datalogger. Still, there are limits to the maximum distance – mostly due to the voltage dropped by the 8032-5 MUX cable over its length. -
