HOW TO PROGRAMME THE INTERFACE WITHOUT A PHONE LINE
In an installation with interface and without a phone line you cannot enter programming.
The only way to enter programming without a phone line is by setting up the following installation:
-
Place a resistance of 220 Ohms/2W between one telephone line terminal, LN, and the power
supply of the interface (positive terminal). The power supply is direct current. For ADS
installations, you can use the 18Vdc of the ADS (in this case it is preferable, though not
necessary, to use an R=330 Ohms/2W instead of the 220).
-
Connect the other telephone line terminal, LN (which has been left free) to the negative. In
other words, the line is connected to the power supply through a resistance.
√ √ √ √ √ VERY IMPORTANT NOTE:
This configuration is provisional, and therefore once the interface has been programmed
•
you must remove the resistance and the bridge to negative.
