In this example, data is written from Data Carrier 1 as HEX code by the write
command. Input the write address in four characters in the range of 0006 to
1FFF, and write data as 2-digit HEX characters. The total character length of the
write data must be 256 or less. Set the communication format of the ID Controller
by using the DIP switches in accordance with the communication system of the
host computer to be used.
