1.0 Introduction
The Conettix D6672 COM1 Expansion Kit (Figure 1)
provides the Conettix D6600 Communications
Receiver/Gateway with an RS-232 interface port
connection to a Conettix D6680/D6682 Ethernet
Network Adapter for Network Communications. Used
in a network system, the D6672 allows connection to
an Ethernet local area network (LAN) or wide area
network (WAN).

2.1 Wiring
When connecting the D6672 to the D6682
Ethernet Network Adapter, use the cable
supplied with the D6682.
For UL installations:
- The D6682 and the D6600 must be
installed on the same mounting rack.
- The cable running between the
D6680/D6682 and the D6672 must be
in metal conduit and no longer than 20 ft
(6 m) if the COM1 is used in a network
system.
2.1.1 COM1 DB9 Connector
The COM1 Port uses a standard DB9 male connector.
Refer to Figure 3.
