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!
The device is not intended for use by persons (including children) with limited physi-
cal, 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 suffo-
cation 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 DTS 2345.serial-distributor is designed for a 19“ rack and should only be oper-
ated installed in a 19“ rack.
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 Observe electromagnetic compatibility!
The device complies with the requirements of EMC directive 2004/108/EC and
96/48/EC

3.2 Device designation in this manual
This manual relates to the DTS 2345.serial-distributor. For purposes of better reada-
bility, the designations serial distributor or simply distributor are used in the following
sections.
3.3 Function description
The DTS 2345.serial-distributor is a signal distributor for the RS232 and RS422 inter-
faces.
The distributor comprises two identical lines. Each line has an input interface and three
output interfaces.
Each input and output interface is individually configurable as a RS232 or RS422 inter-
face. It is not imperative for the inputs and outputs to be configured in the same way.
The signals are transmitted transparently, i.e. without changes to content.
The following illustration shows the block circuit diagram of a line. The signal level is
just prepared and monitored.
The following is the block diagram of a line.

3.3.1 Signal transmission
The signal received at the input interface (Rx connection) is transmitted to the down-
stream devices at all three output interfaces (Tx connection).
In the opposite direction, DIP switches may be used to select which of the data re-
ceived at the output interfaces (Rx connection) must be transmitted to the Tx connec-
tion of the input interface.
The user himself is responsible for the prevention of collisions on the backward chan-
nel. In order to do this he must either activate only the backward channel of an output
interface or ensure by appropriate protocols that at all times only one of the connected
devices attempts to communicate with the superior device.
3.3.2 Bridge mode
With the two DIP switches "Bridge Rx In +" and "Bridge Rx In -", the incom-
ing signals of both input interfaces can be connected to each other.
If both incoming signals are connected to each other, the device works as a
1:6 distributor. In this operation mode, the data received at one of the two input inter-
faces is transmitted to all six output interfaces.
The backward channel is not bypassed. Thus only responses from the three output in-
terfaces that are part of the input interface used can be sent back to the superior de-
vice.
If a particularly high number of outputs are necessary, the unused input interface can
be directed as cascading output straight to another serial distributor.
3.3.3 Monitoring and alarm system
The Tx signal of each output interface is compared with the Rx signal of the corre-
sponding input interface. If a discrepancy is detected, for example because the output
contains a short-circuit, an alarm is activated, which in its turn activates the alarm LED
and the alarm relay.
3.3.4 Display
The status of both input interfaces is shown on the front of the distributor by means of
their Rx LED and Tx LED. The status of each output interface is shown on the back of
the case by means of their Rx LED and Tx LED.
