Introduction
The DSC modem is a communication device designed to enable computer terminals, through use of an RS232 port to
communicate via telephone lines with the DSC line of downloadable security systems.
Although the DSC modem uses the Hayes command set as a template, not all Hayes commands are supported. As a result,
some communication packages that are Hayes compatible may not work.
The modem is compatible with Bell 103-300 and 110 baud data communication standards, using standard Hayes commands.
LEDs
The LED indicators on the top of the modem indicate Power (Red), Received Data (RX) (Green), and Transmitted Data (TX) (Red).
Connections
The six pin connection on the left hand side of the modem is used to connect the modem to the RS232 port on the computer.
The connection is made using the 6 pin - 25 pin adapter that is shipped with the modem and a 6 pin “swapped” cable. When
looking at both ends of the cable (held facing the same way and in the same direction) the color codes of the wires inside the
connectors should be opposite to each other. The right-hand 4 pin connector is where the phone line is connected to the
modem. The middle 4 pin connection is for an optional phone.
Jumper Settings
JP1 selects the pulse dialing option. OFF = North American, ON = European.
Power Supply
Input - 110VAC
Output - 12 VAC, 150mA
Parts
1 DSC modem
1 6-pin patch cable
1 6- to 25-pin adapter
1 12 VAC 800mA power supply
1 4-pin patch cable
Connection to Computer
DO NOT apply power until all connections have been made and verified. Improper connection may damage your computer or
modem.
Connect the 6-25 pin adapter to your RS232 port using the female to female connector. Connect the 6 pin cable from the 6-
25 pin adapter to the 6 pin connector on the Modem.
Connection to Phone Line
On the modem, there are two four-pin connections. The middle 4-pin connector is for an optional phone. The connector on the
right is for the incoming phone line from the wall connector. When the modem is in communication, the optional phone
connection will be automatically disconnected for the duration of the communication.

customer should be aware that compliance with the above conditions may not
prevent degradation of service in some situations.
Repairs to certified equipment should be made by an authorized Canadian
maintenance facility designated by the supplier. Any repairs or alterations made by
the user to this equipment, or equipment malfunctions, may give the
telecommunications company cause to request the user to disconnect the
equipment.
User should ensure for their own protection that the electrical ground connections
of the power utility, telephone lines and internal metallic water pipe system, if
present, are connected together. This precaution may be particularly important in
rural areas.
CAUTION: Users should not attempt to make such connections themselves, but
should contact the appropriate electric inspection authority, or electrician, as
appropriate.
NOTICE: The Ringer Equivalence Number (REN) assigned to each terminal
device provides an indication of the maximum number of terminals allowed to be
connected to a telephone interface. The termination on an interface may consist of
any combination of devices subject only to the requirement that the sum of the
Ringer Equivalence Number of all the devices does not exceed 5.
The REN of this unit is 0.5B.
AVIS: L’étiquette de l’Industrie Canada identifie le matériel homologué. Cette
étiquette certifie que le matériel est conforme à certaines normes de protection,
d’exploitation et de sécurité des réseaux de télécommunications. Industrie
Canada n’assure toutefois pas que le matériel fonctionnera à la satisfaction de
l’utilisateur.
Avant d’installer ce matériel, l’utilisateur doit s’assurer qu’il est permis de le
raccorder aux installations de l’entreprise locale de télécommunication. Le
matériel doit également être installé en suivant une méthode acceptée de
raccordement. L’abonné ne doit pas oublier qu’il est possible que la conformité
aux conditions énoncées ci-dessus n’empêchent pas la dégradation du service
dans certaines situations.
Les réparations de matériel homologué doivent être effectuées par un centre
d’entretien canadien autorisé désigné par le fournisseur. La compagnie de
télécommunications peut demander à l’utilisateur de débrancher un appareil à la
suite de réparations ou de modifications effectuées par l’utilisateur ou à cause de
mauvais fonctionnement.
Pour sa propre protection, l’utilisateur doit s’assurer que tous les fils de mise à la
terre de la source d’énergie électrique, les lignes téléphoniques et les
canalisations d’eau métalliques, s’il y en a, sont raccordés ensemble. Cette
précaution est particulièrement importante dans les régions rurales.
AVERTISSEMENT: L’utilisateur ne doit pas tenter de faire ces raccordements
lui-même; il doit avoir recours à un service d’inspection des installations
électriques, ou à un électricien, selon le cas.
AVIS: L’indice d’équivalence de la sonnerie (IES) assigné à chaque dispositif
terminal indique le nombre maximal de terminaux qui peuvent être raccordés à
