2.1 Installation note

Attention:

It is important to take care that the marked tab connector is connected to the supplied
cable plug. The device always needs to be professionally grounded using a yellow/green
flexible line with a minimum profile of 0.75mm².

2.3 UDL500: RS485 interface

Installation note: We recommend professional grounding of the device (see 2.1

Installation note).

2.4 UDL500: Control digital output via hardware trigger

Installation notes: We recommend professional grounding of the device (see 2.1

Installation note). Output OUT and Input IN are potential-free. Take care that the
grounding will be sufficient (use second tab connector)!

The potential-free input IN may be used to control the reader by a hardware trigger (e.g.
tip switch). The control of the potential-free output OUT can be configured within the
software. For this the reader has to be operated in trigger mode.

In the following example of circuits, the output OUT has not been potential isolated:

2.5 UDL500: Control digital output via software trigger

Installation notes: We recommend professional grounding of the device (see 2.1

Installation note). Output OUT is potential-free. Take care that the grounding will be
sufficient (use second tab connector)!

The reader can be controlled by a trigger signal via software. Therefore, it is not necessary
to use the potential-free input IN. The control of the potential-free OUT can be configured
within the software. For this the reader has to be operated in trigger mode.

In the following example of circuits the output has not been potential isolated:

3. RS485 interface

Most RS485-buses require termination resistors across the conductor pair. The need for
termination has to be checked for each installation. Especially for high data rates, steep
edges or long cables termination resistors are absolutely mandatory. Only both ends of the
main cable, i.e. at the first and the last device, require termination resistors, additional
resistors excessively load the drivers. The resistor value matches the cable´s differential
mode characteristic impedance (in most cases 100 ... 120Ω).

Attention!

This termination resistor (Terminator, 120Ω) has been factory built-in into
all UDL500 and has to be removed if necessary (see chapter 2).

At the RS485-bus you need a controller with fail-safe biasing meaning a pull-up and a
pull-down resistor on the cable. The fail-safe biasing provides a known-state, in which
there is no active driver on the bus. Therefore this is absolutely mandatory regardless of
data rates and length of cables.

Technical data (for baud rates up to 100kBps):

Max. bus length: 1200m (4000 feet)

Max. stub length: because of reflections stubs should be kept as

short as possible; exceptions allow a length up
to 5m (16 feet)

Recommendation for the cable: twisted pair, cable-cross section at least

0.22mm2 (AWG 24) differential-mode
characteristic impedance 100 ... 120Ω

5. Transmission protocol

The RS485 interface is being operated with 8 data bits, 1 stop bit and no parity bit. The
transmission rate can be adjusted to 9600, 19200, 38400 or 115200 baud.
The reader works with the “deBus” protocol. For details refer to document “UDL/UDK
deBus Protocol”.

6. Mounting

The back of the reader is prepared for mounting on masts and tubes. For mounting on
masts or ceilings,deister electronic provides the link holder LRM1 as an ideal supplement
(optional, art. nr. 6103.000).

6.1 Mast/Tube mounting

For mounting on masts/tubes the back of the reader is prepared in the way, that alignment
of the reader around its vertical or horizontal axis is possible. The jagged pipe guidings on
the back guarantee a safe tube mounting with a 360° justification round the tube and a
safe mounting of the reader as well.
