Base Sta tion Link Jack

WTA 1 and WTA 2 audios in the BTR-80N are two in de pend -- ent 2-wire in ter com chan nels. Up to 16 base sta tions may be con nected to gether to share WTA au dio. Do not con fuse WTA au dio with CAN bus data as only 8 base stations may be con -- nected to gether to share CAN bus data. Not only does the WTA Link ca ble pass both chan nels of WTA au dio, it passes a logic level so the 1st base sta tion in the chain is the only one that pro vides a ter mi na tion of the WTA in ter com chan nels. Care must be taken to con nect ca bles be tween base stations from the OUT of base one to the IN of base two and so forth. If the WTA link ca ble is passed from OUT to OUT or IN to IN the WTA au dio may be ter mi nated in mul ti ple places and caus -- ing the WTA au dio level to be greatly re duced.

The base sta tion link jacks can in ter face with other base sta -- tions via two dif fer ent types of ca bles:

Base Link Ca ble (BLC)

•

Straight thru ca ble that passes CAN data, WTA

au dio and WTA ter mi na tion sig nal.

CAN Bus Ter mi na tion Ca ble (CTC)

•

Ca ble that passed WTA au dio and WTA ter mi na -

tion sig nal but does NOT pass CAN data. Acts as a ter mi na tion of the CAN net works on ei ther side of it.

De tailed in for ma tion on the pinout and op er a tion of these ca -- bles may be found un der, "Con nec tion of Mul ti ple Base Sta -- tions with Link Ca bles" later in this sec tion.

Pow er ing the Base Sta tion

The base sta tion may be pow ered two dif fer ent ways:

Line power at the IEC re cep ta cle. Ac cepts 100 - 240

•

VAC, 50 or 60 Hz.

12 - 15 VDC Power. Ac cepts a 5.5 mm by 2.5 mm screw

•

on plug. Source must sup ply at least 3.5 Amps.

Power the base sta tion via a press of the push but ton lo cated to the far left as fac ing the base sta tion.

Turn off the base sta tion by press ing and hold ing the power but ton down for 1 sec ond.

Both line power and DC power may be con nected to the base sta tion at the same time. If AC line volt age d rops th e bas e will draw power from the DC in put au to mat i cally. When the AC line power is re stored to the base the base will again au to mat i -- cally switch back to AC power. There will be no in ter rup tion of base op er a tion dur ing these tran si tions.

Warn ing!: Do not power-up a base sta tion within 3 sec onds of unit be ing turned off. Volt ages within the unit need time to drop be low a thresh old. If pow ered-up within the above time, the unit may boot as the wrong fre quency band.

Sta tus Screen

The sta tus screen is the main in for ma tion screen of the base sta tion. It dis plays a num ber of sys tem items:

How ever in a sys tem with one or more base sta tions with their trans mit ters off, the base-to-beltpack d ata link is lost for these beltpacks.

Mas ter and Ser vant Base Sta tions

A mas ter base sta tion is one that the user has set its base num ber to 01 (Mas ter) and has its trans mit ters on. A mas -- ter base con veys base-to-beltpack data to its beltpacks and, via a base sta tion link ca ble, re lays the base-to-beltpack data from base sta tions that have their base trans mit ters off. A mas ter may sup port up to 7 ad di tional base sta tions with their trans mit ters off. There can be only one mas ter base sta tion in a net work of base sta tions. A mas ter base will au to mat i cally set a 09 (de fault) base to a unique 02 to 08 ser vant num ber. If a base is al ready a ser vant the mas ter will leave it at that same num ber.

A ser vant base sta tion is one that h as its trans mit ters o ff and is con nected to a mas ter base. Since ser vant’s base sta -- tions have their trans mit ters off, base-to-beltpack in for ma -- tion can only get to beltpacks via link ca bles to a mas ter base sta tion.

From the fac tory, base sta tions are set to base num ber 09. This is an un as signed base. This base can be left as 09 if not in a linked sys tem and will work nor mally with all fea tures avail able to it. If con nected to a mas ter base sta tion the mas ter will au to mat i cally as sign a valid, unique, ser vant ID to an un -- as signed base the first time the net worked sys tem is powered-up.

The mas ter base must al ways power-up af ter the ser vant bases in or der to de tect that there are ser vant units to con trol. If all the units are on a com mon power strip, this is con trolled by a built in de lay on mas ter base sta tion. Th e mas ter base sta tion will al ways boot slower than ser vant units.

au dio is planned to be passed be tween base sta tions. There also must not be any base sta tions set to base num ber 01 (Mas -- ter). This is be cause CAN bus is con nected through to the other base sta tions with a BLC as can be seen in the fig ure. If there are no mas ters on the CAN bus sys tem, no ac tiv ity will be on the CAN bus line, thus no need for ter mi na tions.

WTA and a SIN GLE CAN Bus Net work

These base sta tions that may be con nected via 2-wire and/or 4-wire au dio links. They are also con nected to gether via the Base Link Ca ble (BLC). This ca ble passes WTA au dio and CAN bus data in for ma tion. The CAN bus con nected base sta -- tions to gether form a Net work.

Setup

1. Con nect power to the base sta tions. Keep power off to the units.

2. Con nect the trans mit and re ceive an ten nas to the base sta tions. The color dots on the rear of the base should match the color ring of the an ten nas.

3. Connect the main in ter com au dio chan nel(s) to the base sta tions. This may be 2-wire in ter com. This could also be 4-wire in ter com via ma trix type wired sys tem.

4. Con nect the Base Link Ca ble (BLC) be tween base sta tions. Re mem ber to con nect from the OUT of the 1 base sta tion to the IN of 2nd base and fol low the same con nec tion pat tern for ward.

5. Power-up all the base sta tions.

6. The base sta tions should be set to all unique trans mit and re ceive fre quen cies.

7. Setup via the BTR-80N soft ware menus the in ter coms, lo cal head set, aux il iary, stage an nounce, etc. as de tailed in “BTR-80N Op er a tion” in Sec tion 6.

Link Over view

There are two RF data com mu ni ca tion links with a BTR-80N sys tem. They are the beltpack-to-base and the base-to-beltpack links. The beltpack-to-base links con vey in -- for ma tion such as cur rent but ton(s) se lected, bat tery level, etc. The base-to-beltpack links con vey beltpack user ID, beltpack TX shut down, beltpack Talk shut down and other in for ma tion

These two data paths are in tact when there is only one base com mu ni cat ing to beltpacks. They are also in tact when many base sta tions on dif fer ent TX and RX fre quen cies are com mu -- ni cat ing to their beltpacks. How ever when one or more base sta tions that have their trans mit ters off are con nected to a base

sta tion with its trans mit ters o n, the base-to-beltpack data link is lost for these beltpacks.

8. All the base sta tion num bers should be left as 09 (de fault).

9. Turn on a beltpack and only one beltpack. Try to keep the beltpacks at least 6' (2 me ters) away from the base's an ten nas. Set the beltpack on the ap pro pri ate group and chan nel for its base sta tion.

As each beltpack is set to its group and chan nel, an hour glass sym bol will ap pear on the base dis play in the lo ca tion nor mally oc cu pied by the bat tery sym bol. A beltpack will be as signed an ID num ber by the base in this time. Fi nally a n or mal bat tery sym bol will be dis played, in di cated the beltpack has been as signed its ID num ber.

10.Once this 1st beltpack has an ID num ber, turn it off. Now turn on the next beltpack and set it up as in step 9. Con tinue this same pro cess un til all the b eltpacks are set to the proper group / chan nels and have been as signed their IDs. Now all the beltpacks may be pow ered-up.

3. First-On-Latch Out: This locks a base re ceive chan nel so that only one beltpack can trans mit on the fre quency at a time. A beltpack at tempt ing to talk on top of an other beltpack on the same fre quency will hear a dou ble beep in their head set.

2. If the LCD dis plays "Id---" or does not match the base and re ceiver the beltpack is as signed to, Auto Power, Chan nel De se lect and Trans mit Lock out will not work cor rectly.

Bases with trans mit ters en abled are al ways base #1. A sec ond base us ing the first base trans mit ters in stead of its own, and prop erly con nected to the first base thru CAN bus be comes BASE #2, etc.

A beltpack will try to es tab lish its ID au to mat i cally when its group/chan nel is changed. The base must be on for this to work.

On Ta ble 11-1 it can be seen that a C base sta tion trans mit band can be paired with 3, 4, 5, or 6 re ceive bands. How ever, a C2 unit can not be made.

Base RX Freq.

There are 48 groups in a BTR-80N sys tem. The 48 groups are di vided up into 36 fac tory-de fined groups and 12 user de -- fined groups. A group ref er enced to a base sta tion is com -- prised of two TX chan nels and up to 12 RX chan nels.

User-defined groups are blank ini tially and al low the u ser to en ter their own fre quen cies.

Fac tory-de fined groups are com posed of fre quen cies that can not be mod i fied by the user. The 36 groups are com posed of the fol low ing:

9 Trip let groups

•

Groups 1a to 9c

9 Sin gle groups

•

Groups 10-18

The fac tory groups 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. The trip let groups may be used to gether for up to three sys tems that are intermodulation co or di nated. For ex am ple, three intermodulation co or di nated sys tems may be set up by us ing the fol low ing groups and chan nels:

A group also con tains fre quen cies within 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 11-3 in di cates how the fac tory de fined groups used the three TV chan nels for TX and three TV chan nels for re ceive. These plans are based upon US broad cast TV chan nels. A darkened 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. For ex am ple, Group 1A uses at least one fre quen cy from each of the three TV chan nels for RX and only the 1st TV chan nel for TX. How ever group 18 uses only the third TV chan nel for TX and RX.

PROBLEM SOLUTION

DISTORTION - System’s audio quality seems distorted at

medium to high input levels.

HISS - System seems to produce a “hiss” which is undesirable.

LOW OUTPUT - System produces a low output level.

FEEDBACK - Moving around area of use produces

“squeal” or “howl” in various locations using ext. speakers.

DROPOUTS - When moving around the area of use there seems to be locations where the signal “swooshes” or completely disappears.

If you are un able to solve the prob lem, con tact the dealer from whom you pur chased the sys tem for as sis tance.

Reduce microphone gain by adjusting microphone gain control in software.

Check the gain setting on all beltpacks and the base. They may be too low or too high. Check to make sure you are still well within range of the base station.

Check the gain setting on both the beltpacks and the base. They may be too low.

Reduce the gain settings on both the beltpacks and the base. They may be too high. If in 2-wire mode, the intercom channel your are on may be unloaded.

Make sure both antennas on the base and beltpack are connected and follow the location suggestions. Change the location of the base unit and antennas or avoid the bad areas with the remote beltpacks.

INTERFERENCE - System picks up signals other than wireless intercoms.

NO AUDIO from BASE or BELTPACK headsets.

Make sure that all the Telex beltpack(s) are on. If there are any unused receivers at the base, turn the audio off from those receivers by deselecting the appropriate “Portable Station Connect” button.

If problems persist with the beltpack on, you will probably need to change the group. Make sure the base and beltpack match after any Group/Channel change.

Check Transmitter setting on base and beltpack. Check talk LED to make sure it is on. Make sure beltpack batteries are OK.

Bat tery Information

Im proper bat tery se lec tion, use, in stal la tion and care are the cause of nu mer ous w ire less sys tem fail ures.

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 lif e is greater than the leng th 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 r oom 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 lo w tem per a ture the user w ill need to change bat ter ies more of ten.

Bat tery Life:

TR-80N

Al ka line, 9-10 hours typ i cal Nickel Metal Hy dride, 10-11 Hours typ i cal

TR-82N

Al ka line, 6-7 hours typ i cal Nickel Metal Hy dride, 8-9 Hours typ i cal

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. Lith ium 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 b at -- 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 en vi ron ment than alkalines.

En er gizer® is a reg is tered trade mark of Un ion Car bide Cor po ra tion. Duracell® is a reg is tered trade mark of Duracell Inc.
