Installation Guide
Note: The diagram shows an external DC source powering the relay coil. This is necessary whenever coil voltages exceed 5 V.
Both LEDs and 5V relay coils can be powered by the +5 V DC pins on the programmable input connector, as long as the maximum combined current for all LEDS and relay coils does not exceed 100 mA.

WARNING: The Expansion I/O connectors are NOT Ethernet, CobraNet or any other network based device interconnects. Connecting them to Ethernet, CobraNet or other network based device may cause damage to either unit.
In a stacked configuration, one unit must be configured as the Master unit and the others as Slave units. The DMTH4 is normally configured as the last Slave unit in a DM Series chain.
To connect the Master/Slave units, plug one end of a 12

Expansion I/O ports
The four RJ45 connectors on the rear panel are used to interconnect LecNet2™ units together. These ports are only used to transfer digital audio information via the Digital Audio Network Interface (DANI) between the units.
