Wiri g a d I stallatio UDL 250
1. General Infor ation
The UDL 250 is a compact lo g dista ce reader of the UHF type with a i tegrated
a te a. The freque cy ra ge is factory-set a d depe ds o allowed regulatio s for the
particular regio (see also “Tra smissio Freque cy” i chapter 1. “Tech ical Data”).
The UDL 250 has bee specially developed for co tactless ide tificatio of objects withi a
readi g ra ge up to 4 m.
The most i ovative feature of the UDL 250 is its i tellige t a te a co cept, where the polar-
izatio of the a te a ca be adjusted i four differe t ways (circular: RHCP or LHCP a d li ear:
horizo tal or vertical). This i dividual adjustme t allows reliable readi g a d writi g of u favor-
ably positio ed UHF tra spo ders (ISO 18000-6 C / EPC Class1 Ge 2).
The large a d easy to see LEDs sig alize positive ide tificatio for the user.

5. Interfaces
5.1 RS485
Most RS485 buses require termi atio resistors across the co ductor pair. The eed for
termi atio has to be checked for each i stallatio . Especially for high data rates, steep
edges or lo g cables termi atio resistors are absolutely ma datory. O ly both e ds of the
mai cable, i.e. at the first a d the last device, require termi atio resistors, additio al re -
sistors excessively load the drivers. The resistor value matches the cable´s differe tial mode
characteristic impeda ce (i most cases 100...120 Ω).
Attention!
This ter ination resistor (ter inator, 120 Ω) is factory built-in into all UDL
250 and has to be deactivated if necessary (see also chapter 9.1.2 “Basic
Setup” –> “enable 485 ter ination” within the configuration enu “Web-
Config”). The factory setting of this ter ination resistor is “on”.
At the RS485 bus you eed fail-safe biasi g co tai i g a pull-up a d a pull-dow resistor
o the cable which are both built-i i to the UDL 250. The fail-safe biasi g provides a
k ow state i which there is o active driver o the bus a d is therefore absolutely
ma datory regardless of data rates a d le gth of cables. The pull-up a d pull-dow resistors
ca o ly be activated together with the termi atio resistor (withi WebCo fig).

6. Mounting
For mou ti g o walls or ceili gs deister electro ic provides the ball joi t bracket LRM1
(accessory) or the base plate for mast mou ti g LRM3 (accessory) as a ideal suppleme t.
For further details co cer i g accessories refer to chapter 10. “Accessories”.
6.1 Wall ounting with flexible pivot LRM1
For mou ti g o walls or ceili gs the the ball joi t bracket ca be mou ted directly o to
the UDL 250. With the LRM1 the reader ca be positio ed i ma y directio s.
Both mou ti g plates of this device are co ected via ball beari g to a rotatable axis.
Fixi g the correct positio is carried out with a hexago spa er.

6.2 Mast/Tube Mounting with base plate LRM3
Mou t the base plate LRM3 directly o to the back side of the UDL 250 usi g the two supplied
M6 screws with washers. The mou t the mast i the desired directio o to the LRM3 with a
hose clamp.
6.3 Function Principle and Environ ental Influences
The reader se ds a high-freque t carrier sig al. A tra spo der which is located withi the
area of this tra smitted carrier tra smits the sig al back with its ow tra spo der data i a
modulated way. This very weak sig al is bei g a alyzed by the reader.
Because of the particular small-ba dwidth a d the high carrier freque cy withi MHz-
ra ge this system is almost fail-safe. Nevertheless the ra ge of the reader ca be
egatively i flue ced. The followi g list shows what to pay atte tio to:
1. The reader must have visual co tact to the tra spo der. There ust not be any
walls or other devices between reader and transponder. Readi g
through plastic film, card board, papers or glass wi dows may be possible i some
cases, but will reduce the readi g ra ge depe di g o the co ditio of the
material.
2. Water, ice and snow will absorb the carrier signal. Therefore the i staller
should take care, that the fro t of the reader as well as the tra spo der ca ot be
covered with water, ice or s ow.
3. Reflexio s withi the surrou di g of the reader ca i flue ce the readi g result i a
egative way. Therefore the reader should be mou ted as free-sta di g as
possible. We strictly discourage fro sunk-in installations.

Co ectio via USB will create a virtual serial COM Port a d will therefore co seque tly
ask for i stallatio of the appropriate drivers. This driver i stallatio is described i the
accordi g i structio ma ual of the SNG3.

The i terface co verter SNG3 (optio al, see chapter 10. “Accessories”) ca be used for
co ecti g a reader to a host/PC via USB. Poweri g of the reader is carried out as well by
the SNG3 (i case this is co ected to a power supply u it itself). For this a special wall
