I/O Connector
Three 10-pin connectors (P16, 17, and 18) on the back panel provide the connections for the alarm inputs,
outputs, and other data lines. Connect the wires to the 3 terminating connectors provided with the SymDec 4.
See the table below for a description of the pinouts.
Note:
Do not attempt to wire accessories directly to the I/O connector.
Ethernet Port
The cable connection configuration for the ethernet port depends on your network configuration:
•
For a SymDec 4 that connects directly to a hub, use a straight through connection.
•
For a SymDec 4 that connects directly to a PC, use a cross-over connection.
Consult with your network administrator or IS professional for the specific type of configuration. See
Advanced Menu / Communications / Ethernet Settings
on page 70 for information about configuring the
Ethernet settings in the menu system
Table 4.
