C-Tec ECU722 SigTEL Network Communication Card
C-Tec ECU722 SigTEL Network Communication CardNetwork card allows up to 14 ECU-4 8 16 or 8NTs to be interlinked. To network a controller that has an optional ECU-224 desk controller fitted use an ECU723 interfacenetwork card instead.The ECU722 card transmits speech via a single wiring loop and digital data via two linear RS485 networks. The network should be connected using 4 x 2-core 1.5 mm2 enhanced fire-rated cable. Max. length of all networks is 1 km.Key FeaturesAn optional system expansion device.Allows up to 14 ECU-4 8 16 or 8NT SigTEL controllers to be interlinked.One card required per networked SigTEL controller.Allows systems of up to 224 lines 14x ECU-16controllers to be easily set-up.Any ECU-4ECU-8 or ECU-16 can take control of the system at any time by the input of a special code.Note that for networked systems that do not require multiple control points controllers without handsets are available ECU-8NT.IMPORTANT To network a controller that has an optional ECU-224 desk controller fitted use an ECU723 interfacenetwork card instead of an ECU722 the ECU723 is due for release Nov 2019.
