We recommend using a two-wire, shielded cable, e.g. LiYCY 2x1 mm² as the
radio clock cable. One end of the cable shielding must be connected to a suitable
point at the place of installation.
No further assignment of parameters to the GPS1000 is required.
Functional check
The "RADIO CLOCK" LED on the front panel must flash at about 1Hz when the
GPS1000 is received correctly.
The parameter /Inputs/Input 1/Status (0.20.02) must change to "GPS" after about
three minutes reception.
