1.2 Symbols and Signal Words used in this Instruction Manual
Danger!
Please observe this safety message to avoid electrical shock!
There is danger to life!
Warning!
Please observe this safety message to avoid bodily harm and injuries!
Caution!
Please observe this safety message to avoid damages to property and devices!
Notice!
Additional information for the use of the device.
1.3 Intended Use
The DTS 2340.irig-distributor is a signal distributor for IRIG-B 1xx Audio Frequency
(AF) and IRIG-B 0xx Digital (D) signals. The distributor contains two equal lines which
provide their Audio Frequency and Digital imput signal on four outputs each.
For additional functions, see the device descriptions in Chapter 3.4.
1.4 Observe operating safety!
Never open the housing of the device! This could cause an electric short or even a fire,
which would damage your device. Do not modify your device!
!
Caution!

The device is not intended for use by persons (including children) with limited physical,
sensory, or mental capacities or a lack of experience and/or knowledge.
Keep packaging such as plastic films away from children. There is the risk of suffoca-
tion if misused.
1.5 Consider the installation site!
To avoid any operating problems, keep the device away from moisture and avoid dust,
heat, and direct sunlight. Do not use the device outdoors.
The device is designed for 19" racks and should only be operated installed in a 19"
cabinet.
By operating the device, the heat sinks attached to the sides get warm.
Make sure there is enough air circulation for the heat to dissipate.
Danger! Make sure
that you wait before using the device after any transport until the device has
reached the ambient air temperature. Great fluctuations in temperature or humidi-
ty may lead to moisture within the device caused by condensation, which can
cause a short.
1.6 Please observe the electromagnetic compatibility!

3.4 Description of Operation
The DTS 2340.irig-distributor is a signal transmitter for IRIG-B 1xx (AF) and
IRIG-B 0xx (D) signals. The transmitter consists of two identical lines that operate
independently of one another.
Each line has an AF port (BNC connector and spring terminal) and a digital port (spring
terminal).
Each of these input signals is converted to four outlet signals in the IRIG distributor.
The AF signals are transmitted via BNC connectors, and the digital signals are made
available through spring terminals.
Line 1 and Line 2:
Input: IRIG-B 1xx (AF, modulated)
IRIG-B 0xx (digital, unmodulated)
Output: 4 x IRIG-B 1xx (AF, modulated)
4 x IRIG-B 0xx (digital, unmodulated)

Important
:
The analog and the digital signal distribution can be used at the same
time.
Important
:
The digital inputs are only distributed to the digital outputs and the analog
inputs are only distributed to the analog outputs. This means, the digital
and the analog distribution is completely independent.
Important
:
The 2340.irig-distributor can also be used to distribute impulse signals.
For this application the digital in- and outputs are used.

3.4.1 Monitoring
The IRIG distributor measures and monitors the peak of the signal level at each outlet.
Should one of the signals drop below a specified threshold, an alarm will be activated.
The threshold for a valid digital signal is fixed at 2.6V ± 20%. The threshold for monitoring AF
output signals can be adjusted using two DIP switches (see chapter 4.3).
3.4.2 Alarms
An alarm will be activated for each outlet whose signal level drops below the specified moni-
toring threshold.
At any given time, all activated alarms will be combined into one collective alarm. An alarm
LED on the front of the distributor indicates the status of the collective alarm. In the case of
an error, the alarm relay will be switched.
With the use of four DIP switches (see chapter 4.3), monitoring can be switched off for each
of the four inlets and their corresponding outlets. If an inlet is not in use, the corresponding
monitoring switch must be turned off to avoid a permanent error.
3.4.3 Display
An LED on the front of the distributor indicates the status of all input signals. An LED on the
back of the device shows the status of each outlet.
The brightness of the digital output LEDs hints at the load connected to the output and at the
resulting output voltage. The weaker the glow of the LED, the stronger the load of the output.
