Programmable key (Fig. 1)

Allows uploading and downloading the unit operating program by means of the user terminal keys. Proceed as follows:

Copying the key on the EEPROM memory of the unit 1.- Insert the key in the specific base plate connector.

2.- With the unit turned off, press and PRG keys simulta- neously.

3.- Holding these keys down, turn the system on.

4.- Once the copying process is over, the letters CE will ap- pear on the display.

Serial board RS485 (Fig. 2)

Allows connecting the system to a standard RS485 monitor- ing network. By means of the clip-switch system included, up to 199 units can be addressed. For installation, proceed as follows:

1.- Turn the unit off.

2.- Insert the RS485 board in the SERIAL connector of the base plate.

3.- When the serial line connection is being carried out, pay attention to the polarity indicated.

4.- The serial line should be closed by means of a 120 ohms

¼w resistance installed between terminals TX/RX + and TX/RX - of the board located at the end of the network.
