MULTIPLEXED MODE
This mode is selected when device is powered up.
The multiplexed mode allows direct transmission from an instrument.
Mux scan inputs and transmits the value of an instrument as soon as the operator uses the
« transfer » key of this instrument.
The values are transmitted according to the following format:
V x : # u u u u # t t t # s e e e e e . d d d d d d
• x
• #
• uuuu
• ttt
• s
• eeeee
• .
• dddddd

Exemple :
the value -1.25 on channel 2 can be transmitted as follows:
V2:#mm#######-00001.250000

Command '1' to '2' (Mux2), '1' to '4' (Mux4), '1' to '8' (Mux8) (ASCII character 31h to 38h, without
C
L
) receives on Mux RS 232 port, triggers reading of the corresponding instrument, and then

transmit the value.

ADDRESSED MODE
In addressed mode, only one channel (the addressed one) can communicate. The Mux foot switch
can be used.
As soon as it receives a correct addressing instruction on the RS232 port, the multiplexer selects
the corresponding instrument input. It is then working in addressed mode.
Channel selection command
This command is setting up the connection to an instrument. This connection will remain valid until
the reception of a new configuration. The Mux4 does not reply anything to this command.
Command format:
