The Radio Timing GTC may be equipped with 4 types of synchronization:
► TDF or DCF radio synchronization
► GPS synchronization by satellites
► Synchronization via AFNOR NFS 87500 wired link
► Synchronization via ASCII code
► tDF radio synchronization (not available from 01/2017) (Input signal)
The Radio Timing GTC may be equipped with the reference 3F1 antenna (see note)
► DcF radio synchronization (Input signal)
The Radio Timing GTC may be equipped with the reference 3D6 antenna (see note)
GPS synchronization by satellites (Input signal)
►
The Radio Timing GTC may be equipped with the reference 3G1 antenna (see note)
Note: To place your antenna and configure the time offset, please refer to the instructions in
«MDE-ANTENNES-0085» available on: CDG020/021 or on the Gorgy Timing website www.
gorgy-timing.co.uk / documentation / Masterclocks / user manual / Synchronization antenna.
► Synchronization via aFnOR nFS 87500 timecode (Input signal)
Input impedance 3,5KOhms
Minimum level 70 mVcc
IRIG B / AFNOR NFS 87500-compatible input.
Updated upon receipt of 3 seconds of coherent code.
OPtIOn: InPUt OR OUtPUt aScII RS 232/ RS422-485
The Radio Timing GTC can be equipped optionally with 1 RS 232 or RS 422-485 input
or be equipped with 2 RS232 outputs or one RS422-485 output.
► Unidirectional mode - «UnI» position
In this mode, the time base sends or receives the following message at the start of
each second:
STX Day of the week SP day of the month / month / year SP SP Hour: Minute:
Second CR
e.g.: MAR 02/01/01 10:52:25 - Total: 24 characters.
► Bidirectional mode - «Bi» position
In this mode, the ASCII timecode message is sent upon receipt of the character «D»
on the data receipt line.
The time base then sends the following message:
STX hundredths of a second SP day of the week SP day of the month / month / year SP SP Hour: Minute: Second CR
e.g.: 76 MAR 16:03:96 10:52:25 - Total: 27 characters.
