Mounting

It is advised to place the IP (+ GPRS) transceiver in the cabinet of the control panel. If the control

panel has a metal casing it must have a proper earth connection.

If the IP (+ GPRS) transceiver is used in combination with a Alphatronics CP-508LCD or NG control

panel equipped with a RS-485 connection the transceiver can be connected to the RS-485 bus. Use

the 4 blue terminal blocks (+, A, B, O).

If the IP transceiver is used in combination with a random control panel containing a analog dialer

then the analog dialer can be connected to the PSTN input (CMK) of the IP transceiver. If the

control panel's dialer is still connected to a telephone line (or VoIP), remove this connection.

Connect the control panels analog dialer to the PSTN input (CMK) on the IP (+ GPRS) transceiver.

Attention: the cable between the dialler and IP (+ GPRS) transceiver must not exceed 30m.

Connect the LAN connection of the IP transceiver to a free LAN port on the router.

Next, connect the LAN connection of your laptop to a free LAN port of the internal network.
