PXL Controllers
The PXL hardware platform provides sophisticated access control solutions for up to 256
doors at a single site and thousands of doors spread over a number of remote sites. The
unique architecture and latest multiprocessor, RISC-based design techniques allow Keri
to offer the system hardware at a low cost compared to other manufacturers. It also con-
tains many features that simplify and significantly reduce the cost of installation.
The PXL controllers contain all the input/output functionality necessary to manage a
single door (lock relay, door sense, request-to-exit, and two reader inputs) as well as, in
the case of the PXL-500 an alarm output. Each controller has an RS-485 port for con-
nection to other PXL controllers (up to 128 per network) plus an RS-232 serial port for dir-
ect serial or modem communication and an Ethernet port for plugging in a LAN-520
module for Ethernet communication from the PC to the first controller.
