Version 1.2
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).

if this bit is set to 1, coupler will fully reload EEPROM in RAM as if the coupler is powered
on.
