Radio Controlled Clock
You can connect a Wharton Radio Controlled Clock to a Controller to
provide a complete time synchronisation and display system. The
Radio Controlled Clock picks up time signals from Rugby in England
or from Frankfurt in Germany.
Connecting
The Wharton Radio Controlled Clock connects to the RS232
connector CONN1 of the 4101-2 Controller motherboard via a 5810
RS232 Converter. The 5810 Converter is housed in a 25-way D-type
female connector shell and has colour-coded cables coming out of the
back. The 5810 Converter must be plugged into a 25-way D-type
male connector from which connections should be made to CONN1
on the motherboard, as shown in the diagram below.
