Setting Write Protection When Using V600 Commands
There are separate write protection setting methods for the EEPROM (Battery-less) Data Carrier
(V600-D23P@@) and the S-RAM (Built-in Battery) Data Carrier of the V600 Series.
When using V600 commands with a V680-series ID Controller, the conventional write protection set-
ting method can be used by selecting the ID Controller internal setting and the ID Tag type.
- EEPROM Data Carrier: For the V680-D1KP@@, use the V600 EEPROM write protection method.
- F-RAM Data Carrier: For the V680-D2K/8K/32KF@@, use the V600 S-RAM write protection method.
The ID Controller automatically switches between the V600 EEPROM write protection method and the V600 S-RAM
write protection method according to the ID Tag being used, so the user does not need to make this setting.
The V600 EEPROM write protection method and the V600 S-RAM write protection method can be used only on ID Con-
trollers that are version 2.1 or newer. For details on Checking the Version, refer to page 17.
To set the same ID Tag write protection setting area for EEPROM and F-RAM, use the V680 write pro-
tection method.
1. Set the write protection setting of the ID Controller to “Enable.”
• Using the DIP Switch (when pin 1 on SW3 is set to OFF):
Pin 7 on SW4: Set write protection to “OFF” to enable write protection.
• Using the Internal Setting (when pin 1 on SW3 is set to ON):
PARAMETER SET (SP) COMMAND processing code “H”: Set the write protection setting to “1” to
enable write protection.
Write protection is enabled as the default setting.
For details on the PARAMETER SET (SP) COMMAND, refer to Command and Response Formats.
p.175
2. Set the Write Protection Method
INTERNAL SET (SP) COMMAND processing code “J”: Set to either the V600 write protection method
or the V680 write protection method.
For details on the PARAMETER SET (SP) COMMAND, refer to Command and Response Formats.
