Wiegand splitter is wonderful electronic device designed to make every task easy. Managing a project with available resources is a very decisive point of determination for project engineer or designer. Nothing wrong in saying that technology changes against time and every now and then we see new products either with improved technology or upgraded feature making previous obsolete slowly. The key to success is to follow rapid technological shifts with time and implement same without any deviation from accepted standards.
For decades, Wiegand is used as a de-facto communication port, very much acceptable and adopted by security industry. Nothing wrong in saying that 95% of access control industry uses Wiegand devices directly or indirectly. A universal port of communication that helps to neutralize all the technical problems that generally arises due to proprietary protocols for communication.
Imagine a standard two door access controller with two Wiegand ports; then as a rule of thumb it accepts two readers, hence one reader for entry & other for exit or any other combination. Now at the same site, if the need arises to use one more Reader at newly used door or say parking barrier with UHF reader then no other choice is available other than replacing the two door access controller with four door controller. The generic solution makes two door controllers useless and is wasted, and cost of four door controller is much higher than two door controller. The simplified table is as below table 1.0,
The above table clarifies that any additional reader more than two prompts to use new controller with four Wiegand ports. Hence makes existing controller useless for this location and causes unnecessary waste with additional cost of using four Wiegand port controllers.
The simple solution to reduce the cost in addition to using the same existing two door controller is to use Wiegand Splitter NUWG102, Designed & developed by Nundlab, Inc. (USA). The basic features of the device are mentioned below
- 2 readers for 1 port ( 4 readers for 2 ports)
- Auto Wiegand detection (WG26~80)
- Corrosion free contacts
- IP 44 rated
- Expandable & interoperable
- EN50131-1 Security Grade 2
- Environmental Class II
- PCB/ Housing
The cost and waste is eliminated using NUWG102 as per below table 2.0,
The applications are not limited but beyond. Considering the situation like pandemic where use of biometric temperature detection became the norm, the unit can be used to integrate Biometric face and temperature detection units like NBC 123 or NU Bios10 with existing access controllers hence all cabling and procedures are intact as shown in example table 3.0,
The device can help us to keep all existing access control system intact like in parking system using UHF long range readers like NT 910PX; can be integrated with existing access controllers, hence dual frequency card can be used to enter the car park as well as building as show in example table 4.0,
The Wiegand splitter NUWG102 is compatible with any controller and detects the Wiegand bits automatically. However TTL is available for any firmware changes in certain cases.
