This field represents the message contents received or sent by the ERCP 81.

3 OPERATION

3.1 POWER UP

When powered up, the ERCP 81 charges the contents of its memory (EEPROM) in the buffer of
transmission and puts itself in "slave" mode. In this mode, the ERCP 81 does not radiate.
3.1.1
Case where only the serial link is connected
In absence of any order coming from the serial link, it will remain in the slave mode, and will
transmit the contents of the EEPROM to an ERCP 81 "Master" at any request. As of the first
request, the ERCP 81 will be put in the mode defined by the orders, will place the data received in
its buffer of transmission and will remain in this operating mode until a new request or a new
powering (see table 2).
3.1.2
Case where only the input/output are connected
The ERCP 81 charges the contents from its memory EEPROM to the buffer of transmission and it
puts itself in the mode defined by wiring on connector 19 pins (see datasheet).
3.1.3
Case where the serial link and the input/output are connected
Case 3.1.1 applies except if the master mode is imposed by wiring on connector 19 pins. In this
case, the mode imposed by serial link will remain inoperative. The buffer of transmission of the
ERCP 81 will contain, either the contents of the EEPROM, or the data received by the serial link
and will remain unchanged until a new request or a new powering.
