17.2 Type of Communication Texts

This interface function uses the following three types of communication texts:

(1) Output data

Data, such as weight values, that is output from the balance to an external unit

(2) Input commands

Commands to control the balance from an external unit

(3) Response

Response that is output from the balance to an input command

Caution

1.

All of these communication texts can be used for RS232C output.

2.

Only output data (1) can be used for a peripheral output unit.

17.3 Output Data

You can select one from the following three formats in Function 1:

17.3.1 Data format

(1) 7-digit numeric format

Consists of 15 characters including terminators (CR=0DH, LF=0AH). A parity bit can be appended.

(2) Extended 7-digit numeric format

Consists of 15 characters including terminators (CR, LF). A parity bit can be appended.

This is an extended version of the 7-digit numeric format. The extended version is different from the

7-digit numeric format in that:

 the data length can be seven bits rather than eight bits, and

 the stop bit length can be one bit rather than two bits.

The extended version is the same as the normal 7-digit format in other bits. However, if you select

Japanese (katakana) for [

E3. P.F.] (printed language) in Function 1, the data length is automatically

set to eight bits.
