Digital outputs
The following settings select the function of the digital outputs. The hint line shows (off) when the
output is at 0V, and (on) when it is at +V1.
The UP and DOWN keys can be used to select the function from the available list.
If the negative value of the output function is used, the signal sense is reversed. eg 16=motion (out-
put on when weight is in motion), -16=NOT motion (output off when weight is in motion).
The list is shown in the ‘Instruction Manual’ in the ‘I/O Function Table’.

Comms port 1 - RS232
Q2511 COM1 baud rate (8 data, no parity, 2 stop) 8580, g12 19200
Sets the communications speed.
Q2512 COM1&2 modbus address [1 to 30] 8592, g12 1
modbus address.
Q2513 COM1 stop bits 18052, g12 0
stop bits description
0 automatic (1 stop on receive, 2 bits for send)
1 1 stop bit
2 2 stop bits
Q2514 COM1 mode 18060, g12 0
COM1 mode description
0 auto : use extended modbus
1 modbus : use standard modbus
Setting to modbus may speed up the select key in some situations where strict modbus protocols are
required. For example Modbus gateways and convertors.
Q2515 COM1 handshake enable [0=disable, 1=enable] 8584, g12 0
When set to 1, hardware handshaking is enabled. Set to 0 to disable hardware handshaking.
Q2510 COM1 error count 8810, g12
Comms port 2 - RS485
Q2521 COM2 baud rate (8 data, no parity, 2 stop) 8590, g12 230400
Sets the communications speed.
Q2522 COM1&2 modbus address [1 to 30] 8592, g12 1
modbus address.
Q2523 COM2 stop bits 18054, g12 0

See I/O Function Table page 46. Use negative numbers to reverse the signal sense eg 16=motion (output on when weight is in mo-
tion), -16=NOT motion (output off when weight is in motion)
