The Analogue Signal Multiplexer Quick Reference


Jeroen Belleman - February 22, 2006

General

The analogue multiplexer is intended to distribute the signals from the CODD pick-ups to several calibration and observation channels. It has 48 inputs and 8 outputs. Any input can be connected to any output. All ports are 50Ω and have BNC-F connectors. It is a self-contained instrument for mounting in a standard 19" rack. Its height is 3U. Apart from its input and output cabling, it only needs a 230V-50Hz AC supply and a network connection. IP addresses are obtained via the DHCP protocol.

Command summary

Note: Command case is ignored.
SETUP input output- Set up a connection from an input (0..47) to an output (0..7).
CLEAR output- Remove signal from output (0..7).
QUERY [output]- Return input connected to given output. List all connections if output is omitted.
BYE- Close the TCP connection. (It's terminated automatically after a minute of silence.)
