This guide explains how to install and configure the NXT Wiegand-Only Plus Reader Interface Module which is a permanent replacement for the WI (Wiegand-Only) module.
The module connects directly onto one of the communication buses of the NXT or NXT-MSC controller. Once connected, the module configures the controller to recognize Wiegand readers and credentials. The default configuration for the module is for a single-line LED Wiegand reader.
The WI-Plus module supports single line and dual line LED Wiegand readers as well as the NXT-6RK keypad (compatible with NXT credentials).
|Wiring and Layout Diagram
Note: For all other Wiegand reader types, please refer to the reader manufacturer's color code.
The total RIM to reader cable length must be less than 500 feet.
Note: On long cable runs, cable resistance causes a drop in voltage at the end of the cable run. Ensure the appropriate power and current for your device is available at the device (and at the end of the cable run).
* Note: Heavier gauges than those listed are always acceptable.
|Configuring the NXT RIM-WI Plus
The RIM-WI Plus can be configured to support any Wiegand-compatible readers or it can support the NXT-6RK keypad. You can also configure the reader for single-line or dual line LED mode. The default settings is for the module to be configured for Wiegand single-line LED. Once in programming mode, first you select which reader type will be used, then you select if it will be single-line or dual line.
All 7 LEDs will blink three times.
Once in configuration mode, SW1 steps between options - SW2 selects the currently displayed option.
Press SW1 to step through the supported reader types (see the image in section 2.0). Each press of SW1 will step to the next reader type.
When the desired reader type LED is illuminated, press SW2. The reader type is now set.
Once the reader type has been selected you are then ready to configure the RIM’s LED line control mode.
Press SW1 to step through the supported LED line configuration types. Each press of SW1 will step to the next LED line type.
When the desired LED line control mode LED is illuminated, press SW2. The LED line control mode is now set.
Press SW2 twice and the RIM is now configured and the unit reboots to accept the new parameters.
The RIM’s LEDs will be off for about 10 seconds as the unit resets itself. All seven LEDs will flash as the unit is rebooting with the new configuration parameters. When the LEDs stop flashing, the unit is operational.
Note: Do not remove power from the RIM during the reboot process. Loss of power during rebooting will invalidate any configuration changes you have made.
|Verifying RIM Module Configuration
The corresponding reader type and line control mode LEDs are illuminated during operation. Refer to the drawing in section 2.0 for switch and LED locations, and the table in section 3.0 for switch and LED definitions to confirm your configuration settings.
