Step 3 — Connecting Cables
The ECM DIO8 can be powered by an eBUS connection to a control processor, distribution hub, or a 12 VDC power supply. Do
not connect power to either unit until you have read these Attention notifications.
ATTENTION:
•
Always use a power supply supplied or specified by Extron. Use of an unauthorized power supply voids all regulatory
compliance certification and may cause damage to the power supply and the unit.
•
Utilisez toujours une source d’alimentation fournie ou recommandée par Extron. L’utilisation d’une source
d’alimentation non autorisée annule toute certification de conformité réglementaire et peut endommager la source
d’alimentation et l’unité.
•
If not provided with a power supply, this product is intended to be supplied by a UL Listed power source marked
“Class 2” or “LPS” and rated output 12 VDC, minimum 1.0 A.
•
Si le produit n’est pas fourni avec une source d’alimentation, il doit être alimenté par une source d’alimentation
certifiée UL de classe 2 ou LPS, avec une tension nominale 12 vcc et 1,0 A minimum.
•
Unless otherwise stated, the AC/DC adapters are not suitable for use in air handling spaces or in wall cavities.
•
Sauf mention contraire, les adaptateurs CA/CC ne conviennent pas à une utilisation dans les espaces d’aération ou
dans les cavités murales.
•
The installation must always be in accordance with the applicable provisions of National Electrical Code ANSI/
NFPA 70, article 725 and the Canadian Electrical Code part 1, section 16. The power supply shall not be permanently
fixed to building structure or similar structure.
•
Cette installation doit toujours être conforme aux dispositions applicables du Code américain de l’électricité (National
Electrical Code) ANSI/NFPA 70, article 725, et du Code canadien de l’électricité, partie 1, section 16. La source
d’alimentation ne devra pas être fixée de façon permanente à la structure de bâtiment ou à d’autres structures
similaires.
NOTES:
•
Connect up to eight eBUS devices for each IPCP Pro control processor.
•
Wire the connectors in the same way at both ends.
•
Do not exceed a total of 1000 feet (305 meters) of cable for connections between the IPCP Pro and all the eBUS
devices.
•
Do NOT power an ECM DIO8 from more than one power source. Power can be provided by an IPCP Pro control
processor, a PS 1220EB power supply or an Extron 12 VDC power supply. If more than one power source is used in a
system, make sure that the devices powered by the first source are isolated from the devices powered by the second
source disconnecting the +V pin of the first source.
Up to eight devices can be connected to one control processor. In order for the control processor to be successfully configured,
each device connected to the same control processor must have a unique six-bit, BUS ID, which is set with the DIP switch
assembly on the front panel of the ECM DIO8 (see
,
, on page 1). If two or more modules have the same bus ID,
address conflicts may prevent the panels from being recognized by the IPCP Pro control processor. If there is an address conflict,
the status LED (see
,
) lights solidly (see
Step 5 — Testing and Troubleshooting the System
Connecting the eBUS cable
Connect eBUS port (see
,
, on page 1) to a control processor, a power supply, or another eBUS device using a
standard eBUS cable. Before powering on the control processor, read the Attention notifications above. The four connectors are:
•
+V
(red*) — Carries 12 VDC power from the controller, active hub, or power supply
•
+S
(green*) — Carries the positive data signal
•
-S
(white*) — Carries the negative data signal

(black*) and two drain wires — Ground
Extron STP20-2/1000 or STP20-2P/1000 cable is recommended
for eBUS connections. If you use different cable, the wire color
may be different.
The diameter of the ground wire and the two drain wires, when
they are combined, is too large to fit into the captive screw
holder on the eBUS terminal. Use a wire nut to combine a pigtail
wire with the ground wire and the two drain wires. The pigtail is
inserted into the eBUS connector in the usual way, as shown in
, on the following page.
