RL-TA Series Operation Manual 59
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.
