SER - SETTING THE SERIAL COMMUNICATION PORTS

CON1

COM1:

It defines the use of the COM1 serial port.

None:

Serial communication OFF

Contn:

Continuous transmission of the weight string. It can be used,

for example, to drive a remote display. See details in the relevant

paragraph.

Deman:

When the Operator presses the front button or through Input

2, a string of weight is transmitted. The command is accepted if the

weight is stable. Between two consecutive transmissions the weight

must have a variation of at least the parameter “Weight delta”.

Autom:

It’s automatically transferred to a string of weight when the

weight stabilizes at a value higher than the minimum weight (20 divi-

sions). Between two consecutive transmissions the weight must have

a variation of at least the value set in the parameter “Delta Weight”.

Slave:

ASCII protocol. See details in the relevant paragraph.

Modbs:

MODBUS RTU (slave) protocol. See details in the relevant

paragraph.

Selectable Values:
None
Contn
Deman
Autom
Slave
Modbs
Default: Modbs

baud1

BAUD RATE COM1

It defines the RS232 serial port baudrate.
The value must be set to the same value of the PC / PLC or remote

display.

Selectable Values:
2400
4800
9600
19200
38400
57600
115200
Default: 9600
