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 characteristics 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.
Baked black enamel finish or nickel plating finish
Buffer memory
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 events (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.
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.
Phone jackDouble Phone connector type RJ11 on Rev 4 and Rev 5 . Connect Green and Red only on each connector
Power 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.

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 receiver
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

(3x1,4x2) Define code to trigger Listen-In mode in 3x1 or 4x2 formats
Printer/Buzzer Yes = Check printer on DECRYPTA port No= Do not check for printer (default)
By default DECRYPTA does not verify printer status on parallel port but sends data to be printed as if a printer
was connected to this port.
(Yes) option tells the DECRYPTA receiver to verify and report on the status of the printer connected to the
DECRYPTA parallel port. The status verification applies to the DECRYPTA (lowest COM) in the computer if
more than one MCDI receiver is installed. A connector is needed to daisy chain multiple DECRYPTA receivers
to send all output to one printer only.
When Check printer option is enabled (Yes) and the computer is absent, each event being sent to printer triggers
a warning buzzer. This warning sound may be stopped by clicking twice the ON-LINE printer key. Buzzing
resumes if printer is left Off-line.
Do not set the "Yes" parameter if no printer is installed. Multiple error messages could be generated by taking
this action.
Wait after O/H Delay to start Handshake after Off Hook. No = normal, Yes=5 seconds
2 Rings Setting not in use. DECRYPTA set to 1 ring. Setting not Caller ID dependent
Caller ID PC No= Do not send telephone ID data to PC
Yes = Send telephone ID data to PC
Caller ID PRN No = Do not send telephone ID data to DECRYPTA printer
Yes = Send telephone ID data to DECRYPTA printer
Caller ID ALL No = Do not send telephone ID data except when bad transmission occurs
Yes = Send telephone ID data to PC and DECRYPTA printer unless PRN and PC select otherwise
Date / Time Yes = enable(Default) No = disable
Send year Yes = Date including the year No = Date with no year (default)
Yes, tells DECRYPTA to add the Year in date format: HH:mm _ _ MM/DD[/YY] ...
No, by default, tells DECRYPTA to use date and time format: MM/DD.
SA-TLR+ Yes = enable (SA/TLR+/DECRYPTA) No = disable (Default=DECRYPTA)
Surgard Mode Yes = enable No = disable (Default)
ACK delay Wait time in seconds for ACK reception before resend. (Surgard/Native mode only)
Start handshake with 1 1400hz / VFSK
2 SIA / CFSK
3 DUAL 1400hz / 2300hz
4 2300hz
5 STRATEL
6 TELIM
7 ROBOFON
Default sequence is as above. Option is to change first element with the one selected.
Extreme care must be exercised when changing Handshake sequence. It is a well known fact that many dialers
do not respond well to all startup sequences.
