Reader/Writer Setting
Section 4-1

4-1 Reader/Writer
Setting
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 5-2-14 of Section 5). (This does not apply to the communica-
tions settings for the COM2 port).
4-1-1 Host Communications Setting (COM Port Setting)
Make settings for host communications by using the communications port
setting command (CP) (refer to No. 3 in 5-6-14 of Section 5).

This command sets the stop bit for use in
communications with the host.
COM1 Enabled
BCC bit setting *1
(CP command)
COM2 Enabled
Disabled
Enabled
This command sets whether the BCC for
command frames and response frames for
communications with the host will be en-
abled or disabled. Using the BCC is referred
to as "BCC enabled."
COM1 No
ACK/NACK setting *1
(CP command)
COM2 No
No
Yes
This command sets whether or not
ACK/NACK control is performed between
the host and the Reader/Writer. If this control
is not performed, it is referred to as "no
ACK/NACK control."
COM1 5
sec.
Timeout setting *1
(CP command)
COM2 5
sec.
0.5 sec.
5 sec.
This command sets the timeout period for
ACK/NACK control. This setting will be
meaningless unless this command
(ACK/NACK control) is set to ON.
Note
(*1) The communications settings for the COM2 port can also be changed but
will return to the Default set values on resetting the power of the
Reader/Writer.
