ALARM RELAY USAGE
The alarm relay contact information is on the NC, COM and NO connectors. NC is normally
closed when the power is "off" to the DVMD1-X. NO is normally open when power is "off" to the
DVMD1-X. Most users will need the NO and COM terminals. The NC terminal is brought out to
provide both options.
Most alarm systems need to OPEN when:
1. There is an alarm.
2. There is a power loss to the DVMD
3. There is a broken wire from the NO and COM wires to the host
The DVMD1-X is designed to do all three functions using the NO and COM terminals.
1. When the power is "OFF" NO is OPEN
2. When there is an alarm NO is OPEN
3. When there is a broken wire NO "looks" OPEN.
NETWORK CONNECTOR
The Network (RJ45) connector is located on the Back Panel. The communications to the Host
Computer is 100 base T Ethernet provided by an embedded XPORT device.
PTZ CONNECTOR
The PTZ port connections are made with an RJ12 connector crimped on a 6-wire phone cord.
Buy Digikey H2442-25 for short runs up to 25 feet. Intermediate runs to 100 feet need:
1. Digikey part number A9118 (100 pcs of Amp's crimp connector PN 5-555042-3)
2. Digikey part number H0063-100 specifies 100 feet of 6-conductor black phone cord.
3.
Digikey part number PAL1545.1 for an inexpensive crimp tool.
A modular adaptor is needed to connect the DVMD1-X to a serial port on the HOST. Table 2
shows the pinout of the DB9 connector (LCOM REC096F or Digikey 046-0003).

The DVMD is provided with a graphical user interface (GUI) for setup through a program called
ManagerNET.exe
that runs on the PC Host Computer. Most applications will use the factory
default settings; however the user has the option of adjusting these settings to optimize
performance for each camera. The latest version may be downloaded at www.dvmd.com.
