Keri Systems, Inc. Technical Reference Manual – PXL-250 and SB-293
Revision 5.5 P/N: 01836-004 Page 11
1.0 Features
NOTE: This Technical Reference manual was written to support a new revision of the
PXL-250 PCB (released July 2000). This PCB can be identified by its lack of a
removable receiver board on the lower left corner of the PCB. If you are working with
the previous revision of the PXL-250, please refer to v4.1 of the Technical Reference
manual (P/N 01836-003).
1.1 The PXL-250 Tiger Controller
The PXL-250 Tiger Controller is a smart entry controller which contains all the
intelligence and necessary inputs/outputs to manage one door and two readers. In an
access control system, from 1 to 128 PXL-250 controllers can be networked,
controlling from 1 to 128 doors. With the addition of a SB-293 Satellite Board, each
PXL-250 can manage a second door, one reader per door, for a possible total of 256
doors. Refer to Figure 1-1 on page 14 for a basic diagram of a PXL-250 access control
network and its options.
