4-3 Reader/Writer Setting
4-3
4-5
The Reader/Writer has been designed for the user to make all the settings
by issuing commands from the host. The user can use either the COM1 or
COM2 port to make settings. However, we recommend use of the COM2
port because its communications settings have been fixed at factory to
survive a power reset.
In order to fix the information set for the Reader/Writer to survive a
power reset, it is necessary for the user to execute the setting write
command (EW) (refer to 10) in 5-７-14 of Section 5). (This does not apply
to the communications settings for the COM2 port).
