7.6.2 Command and Response Format

The format for commands and responses is as follows.

Format used when sending a command of 132 characters or more

1. First transmission data (131 characters max.)

2. Intermediate data transmission (128 characters max.)

3. Last transmission data (128 characters max.)

Note 1: When a command is divided into several segments for transmission, the first

and intermediate segments end with the delimiter (CR) instead of the terminator.

Note 2: When dividing a write command such as WR, WL, WH, WC, and WD, into

segments, do not divide a 4-character data for a same channel. Divide data by a 4-

character data for a channel.
