●
The maximum response moniter time of the instrument is 2 seconds. So, set the response time-out to 2
seconds.
●
If no response is obtained within 2 seconds, retransmit the same message.
●
The above retransmission is required since a message may not be properly transmitted due to noise or the
like during communications.
Note
When “X” is used as the device ID code in the instruction message, the device
ID code of the response message also becomes “X”. Likewise, the code in the
response message becomes “x” when “x” is used as the device code in the
instruction message.
Use the “X” and “x” device ID codes alternately during message retransmis-
sion from the master station, to make it easier to identify whether the received
response message is the current one or the preceding one.
