Installing a Remote Modem
Because the SD-Node provides only one serial port, you cannot connect an SMS modem and a remote modem at
the same time.
The remote modem is equipped with a 220 V to 12 V transformer, which connects to an external power supply.
The remote modem is a small and light purchased component. Different types of remote modems may require
different installation methods. Use a tie to fix the remote modem in a free position near the SD-Node in the cabinet
so that you can connect cables of the SD-Node conveniently.
The remote modem is connected to an external power supply instead of the cabinet power supply. Ensure that the
remote modem does not affect the cabling of other devices or opening/closing of the cabinet door.
