Register the RPA in the Control Panel see p. 6.1.
7 Test the RPA
1)
Check according to the indication on the RPA, in the PKM Astra
Pro or on the screen "Astra-812 Pro" the status of the RPA (the sta-
tus "Normal" should be displayed)
2)
Run test mode according to User guide. Control the issuance of
notifications on the Control Panel
9.4
If the length of the radial topology SLC is more than 800 m, it is
recommended to install a 100 Ohm terminating resistor (from the de-
livery set) at the SLC point farthest from the RPA to match the Data
line.
R1, R2
– resistor 100Ohm.
