The following information details the various RLINK units and their accessories. The specific model that you order is based on:

• Communication Type
• Type
• Antenna Type

When ordering units:

• The RLINK communication type must match the controller or communication device’s type.
• The RF type (both the power levels and frequency) of each unit must be the same.
• The frequencies of the units and the antennas must be the same.

For example:

• The RLINK connected to a Rotem Communicator must support RS-485.
• Any 900 MHz RLINK can work with any 900 MHz antenna.
• When ordering a 2.4 GHz, 50 mW RLINK, the corresponding RLINK must be 2.4 GHz, 50 mW.

Communication Type

RLINK supports opto-isolated RS-232 and RS-485 communication. The RLINK ordered depends on the communication standard installed in the controller or communication device.

• Communicator or MUX: Order RLINK-485 only
• SuperGuard: Order RS-485 only
• Platinum: Order RLINK-232 or RLINK-485
• AC-2000, RFS-6, RSW-2 SE: Order RLINK-232 or RS-485

CAUTION An RS-485 driver is required to connect an AC-2000, RFS-6, RSW-2 to an RLINK 485.

RF Type

The RLINK can transmit at the following frequencies:

• 900 MHz 1 W
• 915 MHz (Australia) 100 mW
• 900 MHz 100 mW
• 2.4 GHz 50 mW

CAUTION: When using the RLink in conjunction with the RF Center, the RF type must be 100 mW.
NOTE: The 915 MHz (Australia) unit works with any 900 MHz antenna.

Antenna Type

The RLINK supports the following antennas:

• 900 MHz 2 dBi omni-directional
• 2.4 GHz 2 dBi omni-directional
• MHz 8 dBi omni-directional
• 2.4 GHz 6 dBi omni-directional
• MHz uni-directional
• 2.4 GHz uni-directional

NOTE: The 915 MHz (Australia) unit works with any 900 MHz antenna.
