2.1 Data Format

Unless otherwise indicated, numbers in this manual are expressed in hex-
adecimal. Values in double quotation marks, such as “00”, are ASCII.
The number underneath each delimiter in a frame indicates the number
of bytes.

STX

This code (02) indicates the beginning of the communications frame (text).
Always set this character in the first byte.
When STX is received again during reception, reception is carried out again from

the point where STX was received.

Node number

·

This number specifies the transmission’s destination.

·

Specify the E5AN/EN/CN/GN’s “Communications unit No.”.

·

BCD range “00” to “99” and “XX” can be set.

·

Specify “XX” for a broadcast transmission. No response will be returned for broad-

cast transmissions.

·

No responses will be returned from node Nos. set otherwise from the above.

Sub-address

This is not used on the E5AN/EN/CN/GN. Be sure to set the sub-address to “00”.

SID (service ID)

This is not used on the E5AN/EN/CN/GN. Be sure to set the sub-address to “00”.

Command text

Command text area. For details, see “2.2 Structure of Command Text.”

ETX

This code (03) indicates the end of the text.

BCC

Block Check Character
The BCC result is found by calculating the exclusive OR of the bytes from the node

No. up to ETX.
