5.2.2. Receiving mode
In this mode the clock functions autonomously but sets its time according to the ASCII
code received (configuration: 2400 bauds, format 8 bits, even parity, 1 stop bit).
This ASCII code can be:
►
1) – The time information as follows:
STX day of the week SP day of the month/month/year SP SP Hour:minute:second CR
Generated either by the RT3000 or the RADIO TIMING ASCII or any other ASCII
code generator.
►
2) – Or information from another clock of the same type functioning in emission
mode: in this case the first clock is fully slaved to this second clock.
5.2.3. Bi-directional mode
In this mode the time message coded in ASCII is emitted after the reception of a reco-
gnition character (“D”)
(configuration: 2400 bauds, format 8 bits, even parity, 1 stop bit)
►
Message emitted:
STX hundredth of a second SP day of the week SP day of the month/month/year SP
SP Hour:minute:second CR
►
Ex: 76 FRI 03/02/90 15:14:45, which means that the second corresponding to this
message passed to 76 hundredths of a second at the moment when the character
“ D” was received.
☛
In the case of the LEDI 1/60 (which indicates only hour and minute
information), the date information is replaced with zeros and the day of the
week in alphanumerical characters is replaced by 3 spaces. However, if this
clock is receiving AFNOR NFS 87-500 code or if it is radio-synchronised, the
date information is generated.
☛
In the event of a power outage the display goes off but the clock
continues to function thanks to its internal battery. (the hour cue outputs
and the ASCII output are no longer generated).
☛
For clocks receiving ASCII code, if the message received does not have
the right configuration, manual time setting at start-up may be required. As
soon as the ASCII message has been received, the clock compensates for
any discrepancy with the reference time (this adjustment is impossible with
the waterproof version).
