3 Introduction
3 Introduction
This Setup Guide is a systematically structured guide to support you during the initial setup of your Meinberg
product. The individual chapters describe general functions, installation and essential technical data. The Setup
Guide also describes the most important parameters which have to be configured in the respective management
program for a quick startup of your product.
The TCR180USB-EL is a time code receiver for decoding modulated and unmodulated IRIG, AFNOR and
IEEE time codes and is used for time synchronization of computers with no serial interface or no available PCI
slot. It is also suitable for the verification of time code outputs. The board will be configured by the program
MBGMON.

4 General information about time code
The transmission of coded timing signals began to take on widespread importance in the early 1950´s. Espe-
cially the US missile and space programs were the forces behind the development of these time codes, which
were used for the correlation of data. The definition of time code formats was completely arbitrary and left to
the individual ideas of each design engineer. Hundreds of different time codes were formed, some of which were
standardized by the "Inter Range Instrumentation Group" (IRIG) in the early 60´s.
Except these "IRIG Time Codes" other formats, like NASA36, XR3 or 2137, are still in use. The board
TCR180USB-EL however only decodes IRIG-A, IRIG-B, AFNOR NFS 87-500 or IEEE1344 formats.
The AFNOR code is a variant of the IRIG-B format. Within this code the complete date is transmitted in-
stead of the "Control Functions" of the IRIG telegram.
4.1 Description of IRIG-Codes
The specification of individual IRIG time code formats is defined in IRIG Standard 200-04. They are described
by an alphabetical character followed by a three-digit number sequence. The following identification is taken
from the IRIG Standard 200-98):
character bit rate designation A 1000 pps
B 100 pps
1st digit form designation 0 DC Level Shift pulse width modulated
1 sine wave carrier amplitude modulated
2nd digit carrier resolution 0 no carrier (DC Level Shift)
1 100 Hz, 10 msec resolution
2 1 kHz, 1 msec resolution
3 10 kHz, 100 µsec resolution
3rd digit coded expressions 0 BCD(TOY) , CF, SBS
1 BCD(TOY) , CF
2 BCD(TOY)
3 BCD(TOY) , SBS
4 BCD(TOY) , BCD(YEAR) , CF, SBS
5 BCD(TOY) , BCD(YEAR) , SBS
6 BCD(TOY) , BCD(YEAR)
7 BCD(TOY) , BCD(YEAR) , SBS
———————————————————————————————————————–
BCD: time of year, BCD-coded
CF: Control-Functions (user defined)
SBS: seconds of day since midnight (binary)

5 Technical Function TCR180USB-EL
5 Technical Function TCR180USB-EL
The TCR180USB-EL is an IRIG receiver to be connected to the USB interface of a computer and is used to
receive and decode modulated and unmodulated IRIG, AFNOR and IEEE time codes.
With modulated codes, the time information is transmitted by modulating the amplitude of a sine wave carrier.
Unmodulated IRIG codes transmit the time information by variation of the width of pulses.
The automatic gain control of the receiver for modulated codes allows the decoding of IRIG signals with an
amplitude of the sine carrier of 800 mVss to 8 Vss . The potential-free signal input via SMB connectors has an
impedance of 600 Ω.
The input for unmodulated or ’DC Level Shift’ time codes also has an SMB connector. The receiver circuit
of the TCR180USB-EL is insulated from the signal input via an integrated optocoupler.
TCR180USB-EL Setup Guide Date: 15th October 2020 11

5.1 Functional Description
The received IRIG codes are used to synchronize the internal clock as well as the capacitor-buffered real time
clock (RTC) of the TCR180USB-EL, where each received telegram is subjected to a consistency check. If a
telegram error is detected, the internal clock switches to free-running mode. In this case the drift of the time
base is limited by an oscillator control to about 1 µs/sec.
The IRIG codes do not contain a complete date but only an day of year information, the complete date in-
formation is kept in the RTC and in the internal clock of the TCR180USB-EL.
The internal system clock is always set to the received IRIG time, which might have a local
offset to UTC. Only if TCR180USB-EL is configured with this offset, Meinberg driver software is able to set the
system time of the computer correctly.
IRIG telegrams don’t include announcers for the change of time zone (daylight saving on/off) or for the in-
sertion of a leap second. Hence the clock will switch into free running mode in case of such event, and
resynchronize afterwards.
The board TCR180USB-EL decodes the following formats:
A133: 1000pps, amplitude modulated sine wave signal, 10 kHz carrier frequency
BCD time of year, SBS time of day
A132: 1000pps, amplitude modulated sine wave signal, 10 kHz carrier frequency

BCD time of year, SBS time of day
A002: 1000pps, DC Level Shift pulse width coded, no carrier

BCD time of year, SBS time of day
B122: 100pps, amplitude modulated sine wave signal, 1 kHz carrier frequency

B003: 100pps,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

5.2 Internal RTC
If the power supply of the TCR180USB-EL is interrupted the internal RTC continues to run on quartz basis. In
this case the power supply of the clock will be provided by a built-in capacitor which has been charged via the
USB power supply. This allows an independent power supply of the internal clock for about five days.
At restarting the TCR180USB-EL the time/date will be read once from the internal RTC and set as sys-
tem time of the TCR180USB-EL. After five days the TCR180USB-EL cannot read out the correct time and date
from the internal clock during the start procedure and consequently is not able to synchronize correctly to the
received IRIG telegram. In this case it is necessary to set the date and time of the internal clock manually with
the monitor program (see Configuration of the TCR180USB-EL).
5.3 Input signals
Amplitude modulated and Pulse width modulated signals IRIG-A/B (or AFNOR) codes must be connected to
the SMB-jack connector in the housing of TCR180USB-EL. A shielded or a twisted pair cable should be used.
The IRIG code used must be configured with the monitor software.
i
The board TCR180USB-EL can’t be used to decode amplitude modulated and DC Level Shift
signals simultaneously. Depending on the selected code, only the signal at the SMB-connector
is decoded.
5.4 Input Impedance
The IRIG specification does not define values for the output impedance of the transmitter or the input impedance
of the receiver for modulated codes. As a result, the manufacturers of IRIG components have been free to choose
these values, which means that not all devices are compatible with each other. For example, if the generator has
a high output impedance and the IRIG reader has a low input impedance, the signal level at the receiver input
may be too low for the evaluation. Please refer to chapter 6.3 or 6.4 for the input impedances of the respective
signal input.
5.5 Optocoupler Input
Pulse width modulated (DC Level Shift) codes are insulated by an onboard photocoupler.
The internal series impedance allows direct operation with input signals that have a maximum high level
of +12 V (e.g. TTL or RS-422). For higher signal voltages, an additional series resistor must be provided
externally so that the maximum diode current of 50 mA is not exceeded. At the same time, the series resistor
should be dimensioned in such a way that at least a current of 10 mA flows, so that a safe through-connection
of the optocoupler is guaranteed.
