1.1 Reader Interface Module (RIM)

NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part
15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case
the user will be required to correct the interference at his own expense.

3.0 RIM Configuration

The RIM allows either Keri MS or Wiegand readers/credentials to be recognized and read by NXT
controllers. The default RIM configuration is for an MS-Series Reader using two line LED control
(multi-color). Perform the following steps to configure the RIM for your application. Refer to the
Drawing on page 1 for switch and LED locations, and the Table on page 3 for switch and LED
definitions.

Installation Guide

3.1 Enter Programming Mode

1. Hold down both SW1 and SW2 for about two seconds.

2. All seven LEDs on the RIM will flash three times.

3. Release both SW1 and SW2, and the unit is now in configuration mode.

4. Once in configuration mode, SW1 steps between options - SW2 selects the currently displayed
option.

3.2 Select Your Reader Type

The Keri MS (D4), Wiegand (D5), Keri Keypad (D6), and Wiegand Keypad/Reader Combo (D7)
types are currently supported.

1. Press SW1 to step through the supported reader types. Each press of SW1 will step to the next
reader type.

2. When the desired reader type LED is illuminated, press SW2. The reader type is now set.

3. If you have selected Wiegand (D5), Keri Keypad (D6), or Wiegand Combo (D7) reader mode, the
unit is now ready to configure the RIM’s LED line control mode. Skip to section 3.3 for
configuration instructions.

4. If you have selected Keri MS (D4) reader mode, press SW2 twice. The RIM is now configured
and the unit reboots to accept the new parameters. All seven LEDs will flash three times as the
unit reboots 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.

3.3 Select Your Wiegand Reader LED Line Configuration

Dual-line control is the default RIM setting for LED line configuration. This is the desired setting for
the Keri Keypad reader . Perform the following steps to switch between single-line and dual-line LED
control.

1. Press SW1 to step through the supported LED line configuration types. Each press of SW1 will
step to the next LED line type.

2. When the desired LED line control mode LED is illuminated, press SW2. The LED line control
mode is now set.

3. Press SW2 twice and the RIM is now configured and the unit reboots to accept the new
parameters.

4. 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.
