8.3.1.9 Change the Watchdog‘s I
2
C Address
The watchdog‘s I
2
C slave address can be changed to any 7-bit address. This may become nec-
essary to avoid address conflicts on the I
2
C bus, if used in an environment, where the default
I
2
C address "0x6A" is already in use by other slave devices connected to the Java Terminal.
Changing the I
2
C address takes effect immediately and has no impact on the watchdog‘s en-
abled/disabled state.
Command I2C_ADDR
Parameter <address>
Type Number
Range 1-127
Default 106 (0x6A)
Non-volatile Yes
Example WD= I2C_ADDR,87,15 // Changes the I
2
C address to 87d (0x57)
