The rack mount ing brack ets come with each BTR-1. These brack ets may be used to mount a sin gle base sta tion in a 19" wide rack or mount two base sta tions side by side in a rack. Fig ure 5-1 shows the three brack ets that come with a base sta -- tion.

Rack Mount ing Two Base Sta tions Side-by-Side

1. Re move the four pan head screws (two on each side) closes to the front panel.

2. Place the dou ble unit side brack ets on the sides of the base sta tions you wish clos est to the edge of the rack.

3. Re place the two pan head screws and use a third pan head screw (2 sup plied with base sta tion) to screw into the up per mid dle lo ca tion of the rack mount middle bracket.

4. Place the dual bracket on the other sides of the base sta tions. Make sure the bracket is flipped so the front bend is to ward the front of the base sta tion. As you face the rack, the right base station will have the mid dle bracket front bend high and left base station will have the bend low.

5. Re place the two pan head screws and the other pan head screw into the up per mid dle hole of each bracket.

The base sta tion is sup plied with two (2) an ten nas. One 1/2-wave an tenna for Trans mit and one 1/2-wave for Re ceive. The an ten nas have TNC male con nec tors.

The fre quency range of the an ten nas should match the re ceiver and trans mit ter of the base sta tion. Match the color code on the an tenna with the color code on the base sta tion.

ANTENNAS SHOULD BE VERTICAL

The dis tance be tween the base sta tion’s re ceive and trans mit an ten nas is not ad just able when the an ten nas are con nected di -- rectly on the back of the unit.

The an ten nas can be remoted for better sig nal path. A Telex coax as sem bly with re mote an ten nas may be re quired. See “Ac ces sory and Re place ment Parts” sec tion for or der ing in for -- ma tion.

NOTE: If your base sta tion is to be lo cated in a shielded rack mount en clo sure or other poor RF lo ca tion, you must re mote the 1/2-wave an ten nas with coax as sem blies. See “Ac ces sories and Re place ment Parts” sec tion for remote mount ing hard -- ware.

Op er ating Sys tem Near Obstructions

DO NOT - mount the base sta tion 1/2-wave an ten nas on, or

next to metal, such as beams, walls with metal studs, equip -- ment racks, etc. This also ap plies to the an ten nas when as sem -- bled di rectly to the Base Sta tion. This will “de tune” the an ten nas which can re sult in noise or loss of RF sig nal at the base sta tion.

Keep ing the dis tance from the base sta tion and beltpack as short, and un ob structed as pos si ble will pro duce the most re li -- able per for mance.

The base sta tion is sup plied with two an ten nas. This should pro vide sat is fac tory sys tem per for mance in most ap pli ca tions. Sys tem range can be en hanced by remoting the 1/2-wave an -- ten nas.

BTR-1 Op er a tion

Ba sic Op er a tional De scrip tion

The BTR-1 is a full du plex (si mul ta neous talk and lis ten) base sta tion that works in con junc tion with a TR-1 beltpack.

The base sta tion, via the beltpack, al lows com mu ni ca tion with other wire less or wired us ers. The A, B and C but tons on beltpack are as signed their func tions at the base sta tion. The base station also has the abil ity to pro gram the fre quen cies of the beltpack over-the-air. The sidetone for the base station's lo -- cal head set and the beltpack are also ad justed at the base sta -- tion.

If base sta tions are be ing used stand alone (no 2-wire power sup ply) but in ter con nected via the 2W in ter con nect cables, all used in ter com chan nels must be loaded or a loud squeal may re sult.

Sys tem Quick Start

The fol low ing is a list to quickly get a base sta tion and beltpack op er at ing.

1. En sure the base station and beltpack are of the same fre quency bands.

2. At tach an ten nas to base sta tion.

3. Pow er -up the base sta tion.

4. Press <MENU> + <SET> + <UP> + <DOWN> on the base sta tion once it is pow ered up.

5. Load the base sta tion with a AudioCom power sup ply on in ter coms 1 and 2 or place a load on in ter coms 1 and 2.

6. Press <MENU> as pow er ing-up the beltpack.

7. Set the en cryp tion code on the base sta tion.

8. Set the en cryp tion code on the beltpack to match the base sta tion.

9. Set the se rial num ber of the base station in the beltpack.

10. The base should now in di cate a bat tery volt age in di cat ing the base sta tion and beltpack are com mu ni cat ing.

11. Plug a head set into the base station and beltpack. Ad just the mi cro phone gain on both so the overmodulation light flashes only on the loud est ex pected speech level.

Aux il iary port

This jack al lows a bal anced in put aux il iary sig nal to be placed into the base sta tion. It also al lows a bal anced out put sig nal to be brought out of the base sta tion. The in put sig nal can be soft ware se lected to be lo cal or global. A lo cal in put sig nal is only heard at the base sta tion’s lo cal head set and beltpack. A global in put sig nal is heard thoughout the in ter com sys tem(s) the base sta tion is cur rent con nected to via the se lec tion of the beltpack’s A, B or C but ton. The pinout for this jack is in fig -- ure 6-5.

NC = Not Cnnected

The CAN bus ca ble starts at the Fre quency Man ager and then pro ceeds to the first base sta tion. From the first base sta tion, the CAN bus daily chains though all the base stations, stop -- ping fi nally at the Fre quency Man ager. Both base sta tion RJ-45 CAN bus con nec tors are wired in par al lel so it does not mat ter which jack is used for the in put or out put ca ble. See Fig ure 6-6 below for a sam ple rout ing of the CAN bus ca ble. NOTE: For clar ity the power, in ter con nect, and TX/RX ca -- bles are not shown in the fig ure.

Re lay

A soft ware selectable re lay clo sure is avail able at the base sta -- tion. The re lay is nor mally open. How ever the base sta tion soft ware op tions can be set so the re lay closes when the beltpack’s “C” but ton is pushed. The re lay sche matic is shown in Fig ure 6-7.

Fig ure 6-5

Pinout of the Aux il iary Jack

CAN Bus

The CAN bus al lows the con nec tion of mul ti ple base sta tions to a Fre quency Man ager. The Fre quency Man ager then can be use to set all the base sta tions to a fre quency plan plus set a va ri ety of other op tions on the base sta tion. The base sta tions then can pro gram their beltpacks via an over-the-air link. Thus a whole sys tem can be set-up with only a few but ton presses at the fre quency man ager. Each fre quency man ager can con trol up to 10 base sta tion.

Press to en able au dio path from the head set mi cro phone. The talk light will ac ti vate when the talk but ton is ac tive This light has two func tions. Green in di cates ac ti va tion of the talk but ton. Red or flash ing red on most speech in di -- cates overmodulation (too strong of in put au dio).

Overmodulation:

Light flashes on loud est speech = Gain OK Light flashes on all speech = Gain too High Light never flashes on loud speech = Gain too Low

Mi cro phone Gain

The mi cro phone gain of the base sta tion’s head set mi cro -- phone maybe ad just via the pot above the Talk but ton. A plas tic screw driver was pro vided with the base sta tion for this pur pose. Ad just the gain for the overmodulation set -- ting as shown above.

Pow er ing the Base Sta tion

The base sta tion re quires 12 – 15 Volts AC or DC at 1 Amp for power. The power jack ac cepts a 5.5 mm x 2.1 mm screw on plug. An inline 12 Volt DC power sup ply was pro vided with the base sta tion.

Power the base sta tion via the rocker switch lo cated to the left as fac ing the base sta tion.

Start-up

When the BTR-1 is pow ered-up the 1st screen dis played is the start-up splash screen. It will be dis played for about 3 sec onds. This screen con tains the soft ware ver sion and chan nel map ver sions that are loaded into the base sta tion. The fol low ing screen has soft ware ver sion sb10016, and chan nel map ver -- sions B0001 and 30001. This in di cates it is a B3 unit.

Af ter 3 sec onds the sta tus screen will ap pear. See the "BTR-1 Menu Struc ture" sec tion for a flowchart of the main BTR-1 screens.

Fac tory Group Plan

There are 50 fac tory de fined groups in a base sta tion and beltpack. These group are or ga nized in dif fer ent ways to pro vide flex i bil ity to the user on se lect ing fre quen cies. A group is com -- posed of intermodulation free fre quen cies, but a group is also or ga nized to be com posed of fre quen cies in dif fer ent com bi na tions of the TV chan nels. The user then can se lect a group that is clear of broad cast TV chan nels in the area by se lect ing a group(s) that does n’t use those chan nels.

Ta ble 3 in di cates how the fac tory de fined groups use the three TV chan nels for transmit and 3 TV chan nels for re ceive. A shaded TV chan nel in di cates the group has fre quen cies in that chan nel. The white TV chan nel in di cates the group has no fre quen cies in that TV chan -- nel. Group 1 uses at least one fre quency from each of the three TV chan nels for TX and RX. How ever group 50 uses only the third TV chan -- nel for TX and RX.

Al ka line Bat ter ies: Al ka line bat ter ies such as Mallory’s DURACELL® or Eveready’s EN ER GIZER® pro vide the most re li able op er a tion in wire less trans ceiv ers.

The use of low cost car bon-zinc bat ter ies is NOT rec om -- mended.

Nickel-Metal Hy dride Bat ter ies: These bat ter ies can save

you money in the long run, as they can be re charged. Typ i cal bat tery life is about 90% of the length of time al ka line bat ter -- ies last.

Cold Tem per a tures and Bat ter ies

The bat tery life times listed in this sec tion are at room tem per -- a ture. Al ka line and Nickel-Metal Hy dride bat ter ies ser vice hours falls off sig nif i cantly at low tem per a tures due to bat tery chem is try. Al ka line bat ter ies typ i cally have less than half their room tem per a ture ser vice life if used at freez ing 32° F (0° C). Due to the ser vice hours re duc tion of Al ka line and Nickel Metal Hy dride bat ter ies at low tem per a ture the user will need to change bat ter ies more of ten.

WARN ING:

Do not place an al ka line TR bat tery pack in any bat tery charger. Se vere charger and bat tery pack dam age may re sult.

An other so lu tion is us ing Lith ium AA cells if beltpacks are to be used in very cold tem per a tures. Lithium bat ter ies, like the En er gizerâ E2 Lith ium AA cells, are ex cel lent bat ter ies at cold tem per a tures. At the tem per a tures of 15° F (-9° C), Lith -- ium AA cells will last about 7 times lon ger than Al ka line bat -- ter ies. that equates to 2 hours for Al ka line vs 14 hours for Lithiums. How ever, the trade off is Lithiums cost more and are less friendly to the environment than alkalines.
