TECHNICAL SPECIFICATIONSGBInput current.The consumption of video door entry module 68M4, once inserted in monitor 68MV, depends on the operatingmode of the video door entry unit (standby, calling, red/green LED on, activation of controls, etc.).The mean input current values in the three typical operating modes are as follows:- in standby mode 15 mA 0.18W- in call mode 200 mA 3.2W- with monitor on 150 mA 3.0WNOTE: The above values are approximate.Operation of the Elvox Digibus system.The Elvox Digibus system enables digital coding of the devices and commands that are sent to or from the externalentrance panel; the panel can be considered as the "master" device (main appliance managing communicationbetween the digital devices in the system), while every other single digital device can be consideredas "slaves" (secondary appliance that is piloted/controlled by the master).The external entrance panel is therefore essential for the operation of the Digibus system and must alwaysbe installed in the system; all the programming parameters (call time, type of ringtone, electric lock release,code numbers of the indoor stations, etc.) are set and stored (until the next programming) in the mainexternal panel (EEPROM memory).For programming the entrance panel and all the parameters related to it, see the related Elvox technical documentation.The communication protocol used by the Digibus systems is a proprietary Elvox protocol and is “serial-like”with active level at 12 V d.c. (0 V d.c. at rest) and input current during communication on the digital line of 25mA (current limiter on the entrance panel).The standard speed is 600 b/s which enables distances of up to several kilometres to be reached on the digitalbus.Compatible Elvox power supply units.The power supply units that can be used for installing the system are all those in the Elvox Digibus range; Inparticular the following items are recommended:• 6941 (standard audio door entry system power supply unit)• 6948 (standard video door entry system power supply unit).• 6947 (supplementary power supply unit for monitors and call signal).• 6942 (supplementary power supply unit for entrance panels, switchboard and video distributors).For all technical specifications (supply voltage, output current, input current, description of terminals, etc.) seethe Elvox technical manuals.7/36
