One of the RJ-45 jacks connects the C900V2 to 
the Ethernet Network (LAN or WAN). 
The connector pins are listed in Table 3.

A shorting link on P3 selects the voltage and 
current applied to the alarm panel’s telephone 
circuit to simulate the signal from a PSTN 
telephone exchange. For most alarm panels, set 
the shorting link to the H position (short the middle 
and right pins of P3). The L position results in 
slightly lower power consumption for the C900V2 
but some alarm panels might report a telephone 
line failure when dialing the C900V2. 

 

 

For UL approved applications, the 
shorting link must be set to the H 
position. 

 

 

A ten-position DIP switch programs the C900V2. 
The programming depends on the application and 
dialer format of the control panel connected to the 
module.

Because the C900V2 emulates a phone 
line and a digital receiver, you must 
program the C900V2 to the format it 
receives from the control panel. 

 

DIP Switch positions 1 through 4 and 10 program 
the dialer format into the C900V2. Table 4 on page 
9 lists the format programming for these DIP 
switches.
