Communications
For Expansion Commands, any command longer than 271 characters or any response longer than 256
characters is divided into multiple frames for communications. Only the last frame is sent with a
terminator (*CR); all other frames are sent with a delimiter (CR).
1. Responses Longer than 256 Characters (EXPANSION READ Command)
When the ID Controller sends a response frame that is not the last frame, the host device returns a
delimiter (CR). When the ID Controller receives the delimiter, it sends the next response frame.
2. Commands Longer than 271 Characters (EXPANSION WRITE Command)
When the ID Controller receives a command frame that is not the last command frame, it returns a
delimiter (CR) to the host device. The ID Controller can then receive the next command frame.
3. For the EXPANDED READ Command, responses for any command reading more than 240 charac-
ters are divided into multiple frames as shown below. Only the last frame is sent with a terminator
(*CR); all other frames are sent with a delimiter (CR).
Response frames are sent with a 20 ms (default) interval between them.
The send interval can be changed with the SET PARAMETER (SP) command.
