Introduction

1INTRODUCTION

The Wiegand Interface Module (WIM) is developed to be used in combination with

the License Plate Reader. The WIM will convert the license plate string into a

Wiegand output message. The Wiegand interface is supported by many access

control systems.

1.1 KEY FEATURES

•Converts a license plate into a Wiegand output message.

•Output in magstripe or barcode format is also possible.

•Easy integration into existing access control systems.

•Easy user configuration.

•Contains a match-list in which license plates and corresponding Wiegand

output numbers are found.

•Supports a sophisticated algorithm to convert license plates into "unique"

Wiegand output numbers.

•RS485 interface to connect the NEDAP ANPR license plate reader.

•LAN – TCP/IP interface to configure the device and manage the match-list.

2.1 SAFETY PRECAUTIONS

The following safety precautions must be observed during normal use, service and

repair.

•Disconnect the power supply before opening the device.

•The WIM shall only be installed and serviced by qualified and trained

personnel.

•The WIM can be powered from a low power, Class 2 power supply, in

compliance with local regulations.

•To be sure of safety, do not modify or add anything other than mentioned in

this manual or indicated by NEDAP N.V.

4ANPR CONFIGURATION

This chapter describes the required plate reader settings when using the WIM. These

settings must be configured in the plate reader using a web browser and the plate

reader's TCPIP interface. See for more details about the plate reader the ANPR

installation guide.

In this mode, every received license plate message is converted to a Wiegand 26-bit

output message using the SHA-1 security hashing algorithm.

The first four bits are always 0110.

Next 10 groups of 6 bits. Each 6-bit group contains a license plate character. See

character conversion table below.

If the license plate string contains less than 10 characters, the first groups are «

empty » (= 000000).

If a character is not found in the conversion table, then the conversion uses

« other » (=111111).

5.3 WIEGAND MATCH-LIST MODE

In the Wiegand match-list mode, every received license plate message is searched in

the match-list. If the plate string is found, then the corresponding Wiegand output

message will be transmitted. If the plate string is not found, then no Wiegand output

is generated. Optionally a defined Wiegand output message can be transmitted

when no match is found.

The match-list or match-list XL mode is selected with the dip-switches.

The match-list is managed through the LAN interface. This can be done using the

WIM_List software.

See below a screenshot of the WIM_List software.

Figure 5: WIM_List software screenshot

The WIM_List software shows on the left side the match-list. New plates and

numbers can be added to the list. Remove plates by using the popup menu or

pressing the delete key. To view or edit the special plates or the Wiegand output

format, it is required to select the Expert user mode.

On the right side the devices (Wiegand Interface Modules) are shown. Click the

Search button to scan for devices. System administrators and installers require user

mode Expert to configure the devices (e.g. assign an IP address).

Click the transit ('>') or receive ('<') button to synchronize the match-list with the
