DPX-7212
User Manual - Initial Setup and Installation
1. Connect units as shown in Diagram #1. A source of power will be needed for both
units. A single supply can be used to power both units, or a separate supply can be used
for each unit.
2. DIP Switch #1 on both units should be in the “ON” position. This setting places the
units in setup/diagnostic mode.
3. Apply power to both units. After a short delay, both units should begin communicating.
This will be indicated by the Amber communication LED flashing rapidly on both units ,
and the Diagnostic LED flashing Green slowly.
4. Move DIP Switch #1 to “OFF” on both units. The Amber communication LED should
stop flashing. The units are now in Normal “Quiet” mode. This preserves network
bandwidth. Periodically the units will establish contact with each other to verify the data
link. Communication will also occur when a change in I/O status occurs such as a contact
changes state, or a badge is read.
5. Verify Quiet Mode operation. Place a jumper between one of the LED inputs on the
Central unit and Ground. You should see the Amber communication LED on both units
flash to indicate a change of state.
If everything operates up to this point, the units are ready to be installed.
NOTE:
The units are shipped from the factory with a default TCP/IP Address for each unit.
As shipped, they will communicate with each other without changing any settings. If more
than one pair are operating within range of each other at the default settings (same
address) then the units will interfere with each other and unpredictable operation can
result. When performing initial testing on multiple pairs, only test one pair at a time to
eliminate the possibility of interference. If only one pair are in use, the factory default
settings can be left in place.
The DPX-7212 operates in the same manner as the DPX-7000 wired version. This
document covers the network portions of operation. Refer to the DPX-7000 user manual for
details on the I/O and data format operations. The DPX-7212 operates in the same manner
as all other members of the Duprex series, except that the data link is provided by an
Wireless TCP/IP connection.
It is suggested that a bench top verification as described below be performed. This will
provide a known reference point of proper operation, and will greatly aid in troubleshooting
in the event of problems.
