Modules and system devices must be connected using a cable with 0.5 mm
TelevisGo and the last module. Comply with relevant applicable legislation when laying data transmission cables.
Use a shielded cable (i.e. Belden cable model 8762 with PVC sleeve, 2 conductors plus braiding, 20 AWG, nominal capacity
between conductors 89pF, nominal capacity of 161pF between conductor and shielding).
Remember to insert a 120Ω, ¼W resistor between the "+" and "-" terminals of the last device in the network.
To switch the device off, press and hold button (13) for 4 seconds (to prevent any accidental switching off). In the event of
a blackout, the PC and application restart automatically when mains power is returned.
