DPX-7212
Duprex 7212 Description of Operation
The DPX-7212 uses Wireless 802.11 communications to relay door/gate signals and reader data
to an access control panel. There are several parameters that may need to be changed in the
field to use the units at a particular site.
If only one pair of units is utilized at a particular site, and there is no existing wireless network,
then the units will work together right out of the box with no further changes necessary. The two
units will form an “Ad Hoc” network and establish a link between the Central and Remote.
It may be necessary to change some of the network settings if:
a. An existing network is on the site and the user would like to access the modules through the
network. i.e. change settings or mointor status through the wireless network.
b. Secure encryption of the data link is required. See AN-DPX-7212-1 which describes the
process for securing the wireless link.
c. More than one pair of units will be used at the same site.
d. There is a need to change network names or channel numbers to eliminate interference.
If a wireless acess point is available when the units power up, the units will connect the the
access point and use its facilities for communication. If the access point lost due to power or
other problems, the link between the Central and Remote will be lost.
If the units do not “see” an access point at power up, they will form the “Ad Hoc” network and will
ignore any access points not seen at power up. In other words, the access point has to be
powered up and ready before the Duprex units are running.
The following pages detail basic setup and configuration using an 802.11 access point and the
Lantronix® configuration software.
Advanced users can refer to the Lantronix® documentation for further details on the operation
and configuration of the Wi-Port® modules used with the DPX-7212 system.
