3.2 I/O port commands for interface 103 digital I/O

Input/output buffer of the I/O port

Reading of the inputs or setting of the outputs is effected via an input or output buffer. The input and output

ports must be switched in the master mode to EXTERN for this.

Both buffers are separate application blocks.

Reading inputs

Application For reading the inputs of the I/O port.

Command format {A|R|107|ç[ƒ}

Action After receipt of the "AR" command, the terminal sends the 6 input states of the I/O port.

Response format {A|B|6 input bits|ç[ƒ}

Remarks  Input states:

Logic "0" = no current (contact open)

Logic "1" = current flow (contact closed)

 With the ID1 Plus only inputs 1 and 2 are used.

2.3 Technical data Interface 104 RS422/RS485

Interface 104 is a retrofittable interface for the ID1 Plus weighing terminal which can be operated either as an

RS422 (4-wire full duplex) or RS485 (2-wire half duplex). In both cases one peripheral device can be

attached to the weighing terminal.

Factory setting: RS422

Interface mode bidirectional differential voltage interface

Max. operating length 1200 m

Transmission rate 150 - 19200 baud

Galvanic separation optocoupler
