Read/Write DL LCD Keypad Terminal

INTRODUCTION

The ImproX DL LCD Keypad Terminal forms part of the ImproX family of access control equipment. The range features secure, open communications and read/write passive transponder proximity tag technology.

The unit operates as a simple terminal, having no decision making ability. This terminal includes a keypad with night vision backlighting, used for entering data into the unit, a Liquid Crystal Display (LCD) and a multi-tone, multi-volume buzzer.

The unit communicates with other ImproX units via an RS485 Terminal Bus Port and with peripherals via an RS232 Serial Peripheral Port. The data is secure as it is authenticated by means of a 48 bit key.

APPLICATIONS

Typical applications for the ImproX DL unit are as a terminal for:

• Time and attendance monitoring.
• Job costing.
  
• Alarm control
  
• Access control with messaging facilities.

FEATURES

The unit provides the following features:

• A 20-key keypad with backlighting.
  
• A 16-character x 4 line liquid display (LCD) (English, Katakana) with backlighting.
  
• Tag read/write capability (Slim Tags (Read Only), Omega Tags (Read Only), WriTag128 and WriTag 2048).
• Four external digital inputs.
  
• Two independent relay outputs.
• Two independent relay outputs.
  
• Diagnostic LED's to indicate transmit and receive line activity.
  
• RS485 Terminal Bus Port for connection to either a Controller or Host PC.
  
• RS232 Serial Peripheral Port for connection of compatible bar code readers, mag-stripe readers, or keypads.
  
• Operation from power inputs in the range 10 V to 30 V DC.

TAG READING RANGES

The range at which the terminal can read to or write from a tag is dependent on the type of tag and the material on which the particular terminal is mounted. Typical ranges are shown in Table 1.

OTHER INFORMATION

A separate ImproX Secure Communications Protocol manual describes the protocol in detail.

Address Allocation - ImproNet SystemsImproNet Systems automatically allocate addresses to units, either on initial software start-up, or on request, depending on the system configuration. Also, in a system configured for address allocation on software start-up, when the system is started-up after adding a new unit to an existing system, a system address will automatically be allocated to that unit.

Address Allocation - OEM Systems In an OEM system, the unit logical addresses are allocated individually using commands available in the ImproX SecureCommunication Protocol. Details of this process are described in the ImproX Secure Communications Protocol document.
