E. Others
● Above data format and transmission speed may be changed depending on future
development conditions.
● PC operates as Master, and Target Set as Slave in transmission/reception of data.
● No status other than Set Key Function should be received. Provided, however, that con
tents recorded in a set should be always received for alarm function
(Some delay can be happen due to communication speed).
