SECTION 1
OVERVIEW
The DDI-9E is a dua ine externa dia er receiver modu e capab e of processing Contact
ID account information. On y one DDI-9E may be connected to a SYSTEM 3500/3000.
The Digita Dia er interface option a ows the SYSTEM 3500/3000 to receive a arms
through the dia up te ephone network. The dia er option software provides conversion of
coded information from the receiver into the proper format for processing by the
SYSTEM 3500/3000.
The DDI-9E is an dua - ine externa dia er receiver modu e (P/N 425196-0001 and
425196-0002) that wi accept any pu sed dia er rate from 10 to 40 (37) BPS using 3x2 or
4x1 formats. Contact ID format wi a so operate with the DDI-9E. The DDI-9E wi
process a dia er formats now avai ab e with the DDI-7/8 (except the unit cannot mix 3x2
formats with 4x1 formats.). Converting from the DDI-8 to the DDI-9E shou d not require
any setup changes for the existing formats.
The fo owing dia er formats are supported by the DDI-9E:
A - Si ent Knight/Ademco s ow, 10 BPS 3/1, 4/1, 4/2, non-extended format
B - Si ent Knight fast, 20 BPS 3/1, 4/1, 4/2, non-extended format
C - Si ent Knight/Ademco s ow 10 BPS 3/1, extended format
D - Si ent Knight/Ademco fast 20 BPS 3/1, extended format
E - Sescoa, Frank in, DCI, Vertex, 20 BPS 3/1, 4/1, 4/2, non-extended format
F - Sescoa, Frank in, DCI, Vertex, 20 BPS 3/1, extended format
G - Radionics 3/1, 4/2, non-extended format
H - Radionics 3/1, 4/2, non-extended with parity format
I - Radionics 3/1, extended format
J - Radionics 3/1, extended with parity format
K - Si ent Knight, Contact ID (Ademco)
Future re eases of the SYSTEM 3500/3000 may inc ude Modem SIA, Modem CFSK,
FBI Super Fast, Acron, and Ademco High Speed. The DDI-9E can decode these, but the
SYSTEM 3500/3000 cannot process these formats at this time. Digitize wi strive to
imp ement as many of these that are compatib e with the nine-digit account number
structure and the group definitions current y in p ace. Future re eases of new protoco s
wi be free of charge. The upgrades may be obtained by down oading the atest program
from our website when the formats are avai ab e.
The DDI-9E card processes dia er A arm, Troub e and Restore conditions. The SYSTEM
3500/3000 disp ays and prints the incoming DDI-9E signa s. The user can specify
Restora = Yes or No for each account number. After an a arm or troub e condition
appears, the CLEAR button wi b ink if an inva id account number comes through or if
Restora = N for that account number. In this instance the operator can hit the CLEAR
button when the ight is b inking and the condition wi be c eared. If the dia er has a
restora feature, the user wou d se ect Restora = Y, and the dia er wou d send a restora
automatica y.
