SET STATUS
Use
This command sets configuration parameters and coupler’s I/O :
• Communication speed
• Protocols
• State at Power ON
• 2 outputs & 1 input
The various parameters and data used by INSIDE couplers are stored in the EEPROM.
When coupler is powered on, a part of these parameters are load in coupler’s RAM, so that parameters may
be modified in coupler’s EEPROM and in coupler’s RAM.
For a given parameter, RAM and EEPROM address are the same. For example, speed parameter is located at
address 6Dh for both RAM and EEPROM.
✔ When updating a value in the coupler’s EEPROM, this value will be the default value after turning the
coupler on.
✔ When updating a value in the coupler’s RAM, this value will be the current value until the next Power Off.
✔ When writing to EEPROM occurs, EEPROM parameters are reloaded into processor memory (RAM).

Parameters
P1: Sets the type of configuration parameter to update
B7 B6 B5-b2 B1-b0
Reset coupler Reset magnetic field - (RFU) Address
b7 : Resets coupler
if this bit is set to 1, coupler will fully reload EEPROM in RAM as if the coupler is powered on.
Note : when b7 = 1, the coupler responds 3Bh 00h.
b6 : Reset magnetic field
Magnetic field is cut for 20 ms.
When this bit is set to 1, coupler will execute no other action, including EEPROM or RAM update.
