DECRYPTA

Alarm Receiver DECRYPTA

The twin line alarm receiver card DECRYPTA for PC and PC compatible computers is a MCDI product. It carries a five year limited
warranty.

Physical cha racteristics of DECRYPTA

SizeSizeSize

Receiver has all out dimensions:

15” (L) x 5.5” (W) x 2”(H)
38 cm (L) x 14 cm (W) x 5 cm (H)

Housing: Rugged aluminum chassis.

Buffer memory

Printer port

Phone jack

Power connector

Baked black enamel finish or nickel plating finish

Buffer holds up to 800 events in Native mode, 1000 in Ademco emulation Mode. Buffer is used when computer is absent.
Unit keeps printing during fail time if power is connected and maintained. When computer comes back on, buffer empties to

the computer. If more than 800 even ts (1000 Ademco mode) are received in the buffer during fail time, DECRYPTA writes
over the oldest event. Written records may be available on printer connected to parallel printer port.

Connector port for IBM compatible parallel printer type DB25. One printer can be used for all DECRYPTA linked by cables
MRDC2 or MRDC3, instead of one printer per DECRYPTA unit. Events are also displayed on last DECRYPTA for all units.

Double Phone connector type RJ11 on Rev 4 and Rev 5 . Connect Green and Red only on each connector

A twelve (12) volt power input connector is located at the back of DECRYPTA. A 3 foot wire is supplied. Connect red wire to
positive side and black wire to negative side of power source

Alert/WarningBuzzer

On board buzzer is available for alert warning when Computer is absent.
Enable if setup parameter Check printer is set to Yes.
Is activated (start buzzing) by event to be printed on DECRYPTA printer port.
Stop buzzing by pressing twice (2) ON-LINE printer key. Refer to printer connected to DECRYPTA parallel printer port. Will
resume buzzing if printer is left off-line.

CMOS Lithium battery

Receiver memory function support depends on CMOS battery. CMOS battery is located on receiver position BT1. Renata
Model CR2430 or equivalent. Minimum life expectancy 7 years to 10 years. Shelf life: 4 months.

Software tool COMIRQ

COMIRQ is a DOS software program shipped with all receivers. It is used to check signals sent to PC by DECRYPTA. This tool is
very useful to find free IRQ.

To check installation and find free IRQ, run COMIRQ followed by COM,IRQ parameters.
Example: COMIRQ 3,5 (Check if IRQ 5 is free for a DECRYPTA installed on COM3)
When COMIRQ is displayed, send a signal to DECRYPTA where same setup parameters have been given . Signal is displayed only

if COM and IRQ are free. If no signal is displayed, change IRQ in COMIRQ and in DECRYPTA setup. Try again until signal is
displayed indicating a free IRQ.

Press Space bar to display one signal a t a time. Press A to empty receiver buffer and enable ACK.

DECRYPTA

Installing DECRYPTA receiver

Power the DECRYPTA from any 12 volt source. Connect DECRYPTA to a computer serial port using the supplied null modem cable.
It is recommended to connect a printer to the DECRYPTA parallel port. This printer insures a full hard copy backup of all signals

received by DECRYPTA. If a printer is not connected, make sure supplied jumper is connected to printer port.

Configuring DECRYPTA receive r

DECRYPTA is configured using Setup software INITPLUS or internal configuration menus. Configuration in French, German, Spanish
and Portuguese is handled only by internal configuration menus.

DECRYPTA can be configured two ways:

1. Using DECRYPTA display and Menus. See P 8 to 11 of this document

2. Using INTIPLUS setup program. Connect DECRYPTA to PC. See Section above on How to install DECRYTYPA
