If lightning protection 6NH9831-2AA is used, this should be installed whenever possible at
the entrance to the building. To connect the lightning protection to the adapter cable of the
TIM, use a separate antenna cable (BNC female connectors at both ends, similar to the
antenna cable supplied with the indoor or outdoor antenna). You can either assemble this
cable yourself or purchase it from a dealer, for example from Hopf Elektronik GmbH
(www.hopf.com).

GPS receiver

The reception of the DCF77 radio clock signal is limited to western Europe (approximately
800 km radius from Frankfurt am Main, Germany). In regions where this signal cannot be
received, a GPS receiver can be used to acquire the local time from a satellite-based GPS
system (Global Positioning System). For this situation, the SINAUT system includes a GPS
receiver whose output signal simulates the DCF77 signal. This receiver can therefore be
connected directly to the DCF77 receiver in the TIM and can supply the TIM with the current
time.
This GPS receiver ships as a complete package and includes the following:
● GPS receiver module that can be fitted to a 35-mm standard rail
● GPS outdoor antenna for wall or mast mounting, including 25 m antenna cable
● BNC adapter to connect the DCF77 adapter cable of the TIM to the BNC socket of the
Station control system
