The board TCR180PEX-EL decodes the following formats:
A002:
1000pps, DC Level Shift pulse width coded, no carrier
BCD time of year
A003:
1000pps, DC Level Shift pulse width coded, no carrier
BCD time of year, SBS time of day
B002:
100pps, DC Level Shift pulse width coded, no carrier
BCD time of year
B003:
100pps,DC Level Shift pulse width coded, no carrier
BCD time of year, SBS time of day
B006:
100 pps, DC Level Shift, no carrier
BCD time-of-year, Year
B007:
100 pps, DC Level Shift, no carrier
BCD time-of-year, Year, SBS time-of-day
G002:
10 k pps, DC Level Shift, no carrier
BCD time-of-year
G006:
10 k pps, DC Level Shift, no carrier
BCD time-of-year, Year
AFNOR NFS 87-500: 100 pps, DC Level Shift, no carrier,
BCD time-of-year, complete date,
SBS time-of-day, output level adjusted.
IEEE 1344:
Code according to IEEE 1344-1995, 100 pps, DC Level Shift,
no carrier, BCD time-of-year, SBS time-of-day,
IEEE 1344 extensions for date, timezone, daylight saving and
leap second in control functions (CF) segment.
(also see table ’Assignment of CF segment in IEEE 1344 mode’)
IEEE C37.118:
Like IEEE 1344 - with UTC offset to be applied reversely
6.1 Fiber Optic FO Input
The TCR180PEX-EL synchronizes by using pulse width modulated (DC Level Shift) time codes, IRIG-A/B/G,
AFNOR NF S-87500, IEEE C37.118 or IEEE 1344. These are transmitted to the ST connector (fiber optic
input) via a fiber optic cable.
6.2 Signals of the D-SUB9 Inferface
The signals that can be transmitted via the D-SUB9
interface of the TCR180PEX-EL are described more
detailed as follows.
