Failure to follow all safety precautions and instructions may result in property damage, serious injury, or death to you or others. A. GENERAL FEATURES. The Atkinson Dynamics wireless interface unit is a communications device designed for industrial applications that utilize a wired Atkinson Dynamics system and require communication with an Atkinson Dynamics wireless unit or system. The interface unit is housed in a NEMA Type 4X fiberglass enclosure with a hinged screw cover. The nominal operating voltage is 120VAC, 50/60 Hz. The AC power line is fused with a 1/2-amp, 250-volt type GMC fuse. Each unit is equipped with a 7-foot two-conductor audio cable for connection to any wired intercoms in the system. An RF transmitter and receiver, and a “whip” style antenna are contained inside each interface unit. The transmitter and receiver operate in the same frequency band, 902-928MHz, as the Atkinson Dynamics wireless intercom. A four-position switch, located on the printed circuit board inside the unit, allows the user to select the same channel of operation as the wireless intercoms. The wireless interface unit must be set to the same frequency channel as the wireless intercoms to communicate with each other. Refer to section E for details on setting the channel. Each unit is equipped with a squelch adjustment potentiometer, located inside the unit. The squelch adjustment allows the user to set the signal strength threshold level for the RF receiver in the interface unit. Refer to section F for more information on adjusting the squelch potentiometer. Model Specifications Supply Voltage 120VAC, 50/60 Hz Audio Power Output (Max.) Power Consumption (Max.)

After unpacking the Atkinson Dynamics wireless interface unit, examine it for damage that may have occurred in transit. If the equipment has been damaged, do not attempt to install or operate it, and file a claim immediately with the carrier stating the extent of the damage. Carefully check all envelopes, shipping labels and tags before removing or destroying them. C. MOUNTING. CAUTION The selection of the mounting location for the device is to be accomplished under the direction of the facilities and the safety engineer. NOTE The interface unit is intended to be mounted on any relatively flat and rigid surface by the four mounting ears on the exterior of the housing. The four mounting ears are 0.31" diameter holes. Refer to Figure 3 for the proper mounting configuration. Hardware for mounting the interface unit to the surface shall be provided by the installer. NOTE The unit should be mounted right side up so that the antenna (located inside the unit) is facing upward. Failure to do so may void FCC compliance. WARNING For shipboard applications, installations shall be in accordance with the United States Coast Guard, Title 46 CRF, Parts 110-113. D. ELECTRICAL CONNECTIONS. Plug the interface unit into a nearby power source. Each unit is equipped with a power cord that has a NEMA 5-15P molded plug. Connect the audio lines from the interface unit in parallel with the audio inputs from any wired intercoms in the system. Audio wires should be sized properly by your licensed installation electrician for your specified application. See figure 1 for a typical installation. E. CHANNEL SELECTION. Each unit is factory set to channel 3 (909.37 MHz). To select another channel, it is necessary to reconfigure the 4-position switch located on the printed circuit board inside the unit. To select another channel, perform the following steps: 1. Disconnect power from the unit. 2. Open the front cover by removing the four screws and lock washers. 3. Locate the 4-position switch on the circuit board. Refer to Figure 2. Use a nylon probe tool to change the position of the switch. Refer to table 3 for switch settings and their corresponding channel frequency. The setting of position 4 on the switch does not matter because it is not electrically connected. Positions 1 through 3 determine the channel frequency. 4. Close the front cover on the enclosure and reinstall the hardware removed in step 2. The interface unit and all other wireless intercoms in the system need to be set to the same channel to communicate with each other.

EUT Operation The Atkinson Dynamics wireless interface unit is a communications device designed for industrial applications that utilize a "wired" Atkinson Dynamics system and require communication with an Atkinson Dynamics "wireless" unit or system. Each unit is equipped with a power cord that is terminated with a molded plug for 120VAC, SO/60Hz operation. A two-conductor audio cable attached to the unit enables connection to any wired intercom(s)in the system. An RF transmitter and receiver, manufactured by Linx Technologies, are located on a printed circuit board inside the unit. The RF parts operate in the 902-928 MHz band. A switch on the circuit board allows the user to select from eight channels (refer to Table 1below). A "whip" style ~-wavelength antenna is attached to an aluminum bracket that is mounted on the circuit board. An RG-174 coax cable, attached to theantenna, connects directly to the circuit board through a 50-ohm connector. In standby, the interface unit is in "receive" mode. The RF receiver is powered up and the antenna is connected to the receiver through an antenna switch. The interface unit may receive audio from a wired intercom at the interface connector Jl, or from a wireless intercom within range at the receiver "ANLG-QUT" pin. When the interface unit receives audio from a wireless intercom, the signal passes through a low pass filter and noise reduction stage to a preamplifier circuit. This signal then passes through a relay to connector Jl where it is broadcast on any wired intercoms that have audio lines connected to the interface unit. When an audio signal is present at interface connector Jl, it is routed through two different paths on the circuit board. One path is through an audio sense circuit. When audio is detected by this circuit, the transmitter turns on and the receiver turns off. The antenna is switched from the receiver to the transmitter. The second path for the audio at Jl is to relay K2. Once K2 energizes, the audio passes through to an attenuation circuit and then to the transmitter ANLG-IN pin. The audio signal will then be broadcast on any wireless intercoms that are within range of the interface unit's transmitter. All units are equipped with a squelch adjustment control potentiometer that is located on the circuit board. The squelch adjustment allows the end user to adjust the signal strength threshold level of the RF receiver in the interface unit. The incoming signal level must be higher than the signal strength threshold level for the receiver to acknowledge it; otherwise, the audio will be squelched.

HOW THE EUT MEETS THE REQUIREMENTS OF 15.31 (e) The fundamental was maximized on the test site using a normal test setup with the Wireless Interface Unit Model: ADWI (EUT) power cord connected directly to the AC public mains (115 VAC). Next, the EUT’s power cord was then connected to the Staco Energy Products Variable Auto Transformer Model: 3PN1010. The Variable Auto Transformer allows the Vac input to be varied. The EUT’s power cord was then connected to the Staco Energy Products Variable Auto Transformer Model: 3PN1010. The AC input was then dropped to 85% (97.75 Vac) and raised to 115% (132.25 Vac). The actual AC input was measured using a calibrated Fluke Multimeter Model: 87, Serial Number: 51350019, Calibration Due Date: July 11, 2004. The fundamental was then verified again to see that the amplitude did not change. Test Result: The Wireless Interface Unit Model: ADWI (EUT) does NOT change amplitude at the fundamental when the AC input voltage is varied between 85% and 115% of the input nominal rated supply voltage.
