RECAUTIONS
Some devices used in the ParSec reader are static sensitive.
Anti-static precautions must be taken when handling the printed circuit boards.
Static discharge will permanently damage the boards.

2.1. Reader Design
The reader is mounted in a 2-part enclosure for surface mounting. The rear casing has 2
keyholes and 1 slotted hole for the 3 fixing screws and a variety of knock-out positions for
ease of cable entry.
The reader contains two PCB’s for ease of installation and maintenance. The rear B
ACKPLANE
P
CB
comprises two cable termination blocks, the power supply regulator and alarm relay, and
two connectors to the front L
OGIC
P
CB
. The Backplane PCB will normally remain
permanently mounted after the reader case has been sited and the cables installed.
The L
OGIC
P
CB
contains the radio receiver, the microprocessor and communications circuitry,
and the K
EY
PIC personality module. All reader adjustment and configuration is performed via
the logic PCB, which is mounted onto the Backplane PCB via two push-fit connectors.
This method of construction enables replacement of the logic PCB for maintenance purposes
and also makes it possible for the physical mounting and cabling of the reader enclosure and
Backplane to be carried out prior to system configuration and commissioning.
The reader front cover is protected from unauthorised entry by a recessed security screw.
For this to be removed for installation, you will need a Newmark security driver (Part no
SS0001 or RS part 541-983). Any attempt to remove the front cover will operate an anti-
tamper switch which may be set to trigger a local or remote alarm (e.g. sounder/lamp) and, if
the reader is connected to a computer-based system, to raise an alarm at the system control
console.
There are 2 types of reader. The model PSR-232-1 has an RS232 port and is normally used
with TransAsset or other third party asset management software. The model PSR-W26-1 has
a 26-bit industry standard wiegand card type data output and is normally used with access
control systems. It is possible to convert from 1 model to another by simply changing the
socketed KeyPIC.
All the tags transmit at 418 MHz using a power level which in the UK is MPT 1340 licence
exempt by the DTI. For those countries where 418 MHz is not acceptable, tags and readers
operating at 433 MHz will become available in mid 1998. All units are CE marked and
comply with European EMC directives. However, to maintain this compliance, it is essential
that you follow the installation procedures in this manual and in particular use grounded
screened cables where specified.
