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).
