General Description
This manual only covers the setup of the serial output option. Please refer to the main display's
operating manual for full specifications, installation methods, safety notices etc. You can
download manuals from our website.
The serial output option allows you to create an isolated RS232 or RS485 signal which provides
data proportional to the nett or gross value shown on the front of your display.
This can be used to feed remote devices such as data loggers, displays, PLCs and other
peripheral equipment.
There are 2 different option boards available:-
1.
An RS232 board, for short distance point to point transfer of data
2.
An RS485 board, which is suited for longer distance transmission and which may
be part of a group of addressed instruments.
Both boards can be set to transmit continuously or can be requested to transmit by a data
request.
Maximum recommended cable distances if using LOW
capacitance screened cable such as CAT5 cable.

The serial output is derived from the displayed value, so if you adjust filtering for the display,
the serial output will also be filtered and will respond to any input changes at the same speed
as the display.
The serial output is updated 10 times per second when in continuous mode.
