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 2345.serial-distributor is a signal distributor for the RS232 and RS422 inter-

faces. The distributor comprises two identical lines, each of which connects their input

interface to three output interfaces.

Please refer to section 3.3 – Function description – for a detailed function description.

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!

Please make sure that the device remains clean especially in the area of the con-

nections, the control elements, and the display elements.

Clean your device with a damp cloth only.

Do not use solvents, caustic, or gaseous cleaning substances.

2.3 Disposing

Device

At the end of its lifecycle, do not dispose of your device in the regular household rub-

bish. Return your device to your supplier who will dispose of it correctly.

Packaging

Your device is packaged to protect it from damages during transport.

manner and properly recycled.

3 General Information - introduction

3.1 Scope of delivery

Please check that the delivery is complete and notify your supplier within 14 days of re-

ceipt of the delivery if it is not complete.

In the package purchased by you, you have received:

DTS 2345.serial-distributor

1 actuation tool for spring terminals

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.

4 Configuration, displays and connections

4.1 Status displays on front

On the front of the case the status of the device is displayed by means of six LEDs.

tion of the interface, the switches for the configura-

tion of the outputs and the signal LEDs for monitor-

ing the status of both interfaces.
