7.2 Bluetooth settings
The followings are Bluetooth setting items. These are configurable by the commands.
(1) Authentication level (Level 1, Level 2-1, Level 2-2, Level 3)
(2) PIN code (alphanumeric characters and symbols (20H, 21H, 23H-7EH) 1-16 digits)
PIN code (Personal Identification Number, pass key) is an authentication password in 1-16 digits used for printer
identification. The PIN code is needed when the authentication level is Level 2-1, Level 2-2 and Level 3. Link key will be
generated automatically after PIN code authentication and pairing start in the printer. Once the link key is generated, there is
no need for PIN code authentication. The printer can be connected without checking the PIN code during the pairing.
The module of Bluetooth specification version 2.0 supports Fast Connect. Pairing information can be saved in the printer for
8 units. When pairing has done with more than 8 units, the printer deletes the oldest pairing information and save the new
pairing information. (The pairing information will not be cleared by the factory clear.)
(3) Communication parameter (ISI, ISW, PSI, PSW)
ISI, ISW, PSI, and PSW are setting values of Bluetooth module. The details are as below.
Setting
Description
ISI (Inquiry Scan Interval)
Time interval of ISW (0000, 0012 - 1000)
(0.625 msec unit)
ISW (Inquiry Scan Window)
Respond time against search request from the host (0000, 0011 - setting
values of ISI)(0.625 msec unit)
PSI (Page Scan Interval)
Time interval of PSW (0012 - 1000)
(0.625 msec unit)
PSW (Page Scan Window)
Respond time against search request from the host (0011 - setting values
of PSI)(0.625 msec unit)
-Device search request from the master device can be rejected when ISI=000 and ISW=0000.
-The default values after the factory clear are ISI=0x800 (1.28 sec), ISW=0x12 (11.25 msec), PSI=0x800 (1.28 sec) and
PSW=0x12 (11.25 msec).
-It is impossible to set ISI<ISW or PSI<PSW.
-The communication parameters are not necessary to be changed normally. However, communication parameters are
needed to be adjusted when the field intensity is not strong enough.
(4) Device name (alphanumeric characters and symbols (20H, 21H, 23H-7EH) 1-20 digits)
By setting device name, the name can be displayed at the connected device and the printer can be identified.
Note: Only the first start-up after setting this command will process the new settings for Wireless LAN interface. Do not power off
the printer when the printer is rebooted until the printer starts up normally.
7.3 CRC Transmission Data
The transfer format of send data needed to be configured as follows when CRC check mode is selected.

CRC
2 bytes
Calculated by the method called CRC-ANSI. Send error control value
that was calculated by CRC-16 (Generating function
X16+X15+X2+1*2) in order of [High] and [Low].
1) Use this command in between Start of Data Transmission <A> and End of Data Transmission <Z>.
Set STX and ETX for print data. The printer will not print if there is no STX or ETX in the print data.
2) This is shifted to the right; therefore, the value actually used for calculation is [0xA001]. Also, initial value is set to "0".
