5.0 SERIAL OUTPUT (option)
"MPCIB396 P6" series models can communicate with an host computer along an
opto-isolated RS232, RS422, RS485 half duplex serial line.
Unidirectional serial output
"MPCIB396 P6" series instrument with unidirectional optoisolated RS232 output
send out the readout value when the
key is pressed or shorting the terminal 18
or 19 if programmed to this function (see paragraph “TERMINALS 18 AND 19
CONFIGURATION”). Serial output features are listed in the table below, and the
wiring diagram is shown in fig F. The output format is as follows:
H.T. T.T. T. H. tens unity LF CR
Bi-directional serial output
It is possible to program or read the most of the keyboard function of one or more
instruments linked with each other (31 max) by this line transmission. All messages
are sent and received by means of an ASCII protocol.

To use the instruments “MPCIB396 P6” models with RS485 or RS422 serial output,
you must follow figure “G”, for RS232 serial output follow figure “F” program the
instrument with the address code and the BAUD RATE and realize a supervisor
software using the mnemonic codes described in the following pages.
The address code, which must be assigned at the instrument, is the name by which
the host computer calls the instrument that must receive or send information by the
serial line. To program the address code and the baud rate (functions programmable
only by keyboard) follow the next table.
