SECTION 2. EQUIPMENT SETUP BASE STATION SETUP Basic Base Station Setup The following description is for a basic, stand-alone DX121 One-to-One Wireless Intercom System setup. Intercom headset, 4-Wire intercom and relay connections are described on page 22. Set up the Base Station as follows: Approximate 90° angle Antenna connectors 12-14 VDC power connector Rear Panel Power light Power button Front Panel Step 1.
Step 2. Connect power • Plug the connector at the end of the AC power supply cord into the 12-14VDC power connector on the rear panel of the Base Station, and turn the nut on the connector clockwise to secure it to the Base Station. • Plug the female connector at one end of the power cord into the AC power supply, and plug the other end into an electrical outlet. • Press the POWER button on the front of the Base Station to turn it on. The red light above the button should go on.
Interference Avoidance Interference, which may be heard in a headset as popping sounds, may occur whenever other equipment such as WI-FI systems, wireless DMX systems, other HME Base Stations, etc. use the same frequency band. If these systems can be limited to one portion of the band, then the DX121 can be set to the opposite half of the 2.4 GHz to 2.48 GHz band.
Base Station Initialization For multiple HME Base Stations to operate without interference, they must be properly initialized before performing any other setups. After initializing each Base Station, register each COMMUNICATOR® that will be used with that base according to the procedures on pages 13 – 20. NOTE: Base stations must be set up for split-band operation prior to initialization. (See Interference Avoidance on page 10.) • Turn the primary Base Station power on.
• Repeat these steps for each remaining secondary base. Use a different number for each. Only the primary base and the secondary base you are working with should have power on during initialization. All other equipment should be off. • After all secondary bases are initialized and COMMUNICATOR®s are registered power up all bases. Press RESET on the primary base and let it recover. Turn on the primary Communicators and let them link.
BELTPAC / ALL-IN-ONE HEADSET / SPEAKER STATION SETUP AND REGISTRATION The first time you operate the DX121 system, you must register each BP200 Beltpac, WH200 All-In-One Headset and/or WS200 Speaker Station COMMUNICATOR® for use with a specific Base Station. The Base Station will then recognize all registered Communicators when their power is on, and will know the difference between them and other electronic equipment operating on the same frequencies.
If registration is successfully completed: • • A voice message in the headset will say “Power on, Beltpac #, Version #, Begin registration, Registration complete, …” After a delay of up to 15 seconds, the STATUS display will show the ID number assigned to this Beltpac for about 10 seconds. NOTE: ID numbers are assigned sequentially as 0 thru 3. The power light on the Beltpac, next to the IC button, will remain on steady green.
Set Up All-In-One Headsets Before registering them, insert a fully charged battery in each Headset, with the metal contacts on the end of the battery inserted first. Press it in until it snaps. Power On/Off • To turn power on • Press and release the power button on the inside of the Headset housing. A voice message in the earpiece will say “Headset #” and the power light on the opposite side of the earpiece will go on. To turn power off Press and hold the power button for approximately 3 seconds.
If the registration is successfully completed: • • A voice message in the Headset will say “Power on, Headset #, Version #, Begin registration, Registration complete, …” After a delay of up to 15 seconds, the STATUS display will show the ID number assigned to this Headset for about 10 seconds. NOTE: ID numbers are assigned sequentially as 0 thru 3. • • The power light on the Headset will remain on steady green. Repeat Steps 1 to 3 at the bottom of page 15 for each Headset to be registered.
Set Up Speaker Stations The Speaker Station can be used together with Beltpacs and All-in-one Headsets. It provides wireless communication through its built-in microphone and speaker, or a plug-in headset. A remote speaker can also be connected to the unit. The Speaker Station can be used on a table top or mounted on the wall. It can be operated with standard AC power, 12-14VDC or with six AA batteries or an optional rechargeable battery. A power supply with cord and a battery sled are provided.
Battery Operation If using the Speaker Station with battery power ― • Press down and pull out on the two battery cover release latches and lift the cover to open the battery compartment. • Insert six AA batteries into the battery sled, in the positions shown inside the sled, and install the sled in the battery compartment. Battery compartment Battery sled with batteries NOTE: An HME BAT850 Rechargeable NiMH Battery can be used instead.
Register Speaker Stations The first time you operate a Speaker Station, you must register it for use with a specific Base Station. The Base Station will then recognize the Speaker Station when its power is on, and will be able to tell the difference between it and other electronic equipment operating on similar frequencies, or DX family Beltpacs or All-in-one Headsets. NOTE: The Speaker Station must be within 6 feet (1.83 meters) of the Base Station while being registered.
If registration failed: • A voice message will say “Power on, Speaker, Version #, Begin registration, …” The ISO and IC lights on the Speaker Statio n will be blinking red, and there may be a delay of up to 90 seconds before you hear “Registration failed,” and the STATUS display (#4) goes blank. • Press RESET (#7) on the Base Station. To press RESET, insert a small paper clip or similar object into the RESET hole at the lower-left corner of the Base Station front panel.
