Phoe nix Field Unit Man ual VI. TAM In ter face The Uni corn/Phoe nix/Peg a sus se ries of traf fic coun ters all sup port an op tional TAM (Take Away Mem ory) In - ter face Board. This “in ter face” con sists of a plug in slot on the face panel of the coun ter and one or more TAM Cards.
Phoe nix Field Unit Man ual VI.b. Trans ferring TAM Data to your PC The next two sec tions, VI.c. and VI.d, cover how to put data col lected by a traf fic coun ter onto a TAM card. This sec tion cov ers how to get this data off of the TAM and into your PC. To do this you will need to use your coun ter as a TAM Mem ory Card Reader.
Phoe nix Field Unit Man ual VI.c. TAM as ex tended mem ory for your coun ter The coun ter co mes de fault with 68K of data stor age. If you plan on col lect ing a lot of traf f ic data be tween re - triev als, your coun ter may run out of mem ory and stop col lect ing.

Phoe nix Field Unit Man ual VIII. Call-Back Sys tem The Phoe nix has a func tion which al lows the coun ter to ac tu ally call up a re mote com puter with a mo dem and make a re port if a par tic u lar lane goes down. This could hap pen if a sen sor fails (such as a loop) or there is some sort of other prob lem which causes the sys tem to stop col lect ing data prop erly.
Page 73
Phoe nix Field Unit Man ual Fol low the be low steps to setup your com puter to re ceive Call-Backs: 1) Con nect your com puter to a smart mo dem that is con nected to an out side line. 2) Run the TT-Link Soft ware.
Phoe nix Field Unit Man ual Appendix A.Trou ble shoot ing This Sec tion is in tended as a guide to wards in stal la tion trou ble shoot ing. It is in no way in tended for the ser - vice or re pair of any type of Phoe nix sys tem.
Phoe nix Field Unit Man ual Appendix B.Mem ory Us age Each mode uses a dif fer ent amount of mem ory for stor ing traf fic data. This ap pen dix is in tended to give the user an ap prox i ma tion of how long a Phoe nix Field Unit may col lect data be fore re trieval must be per formed. Note that this is only a guide - it is rec om mended to re trieve data as of ten as is prac ti cal from the units, and de let ing re trieved files from the mem ory (un less Erase First File When No Mem is en abled).
Phoe nix Field Unit Man ual Appendix B.2. Binned Data Col lec tion Binned data stores data as the to tal num ber of ve hi cles in each bin cat e gory ev ery re cord i n ter val. The three most im por tant fac tors are: Which bin cat e go ries are en abled, What are the re cord in ter val lengths, and How many lanes are en abled.
Phoe nix Field Unit Man ual Appendix B.3. Count Data Col lec tion Count data stores the to tal num ber of ve hi cles (if us ing a pres ence sen sor) or the to tal num ber of ax les that crossed the sen sors for a given time pe riod.

Phoe nix Field Unit Man ual Appendix E.Road Tubes Prob lems & So lu tions This ap pen dix dis cusses the var i ous prob lems that road tubes can cause. Road tubes pres ent their own unique set of prob lems for au to matic ve hi cle clas si fi ers & coun ters. Be ing aware of these po ten tial prob lems be fore in stall ing your road tubes can greatly re duce the fre quency of these prob lems.
Page 89
Phoe nix Field Unit Man ual n Sound Wave In ter fer ence. To un der stand why this is a prob lem, you should un der stand that the Phoe nix airswitch (like all airswitches) uses a “sound wave” to de tect an axle hit. This wave is very sim i lar to a wa ter wave, in that it starts at a point and moves down the road tube to the round piezo disk sen sor in the airswitch.
Phoe nix Field Unit Man ual The ques tion then be comes, if this is caus ing missed ax les, why does a shorter road tube work b etter? If you take a 30’ road tube, stretch it 50". Sound Wave “D” will start at about the 24’ mark, and there fore will take only 21ms to reach the airswitch.
Phoe nix Field Unit Man ual Appendix E.3. Bad Speed and/or Length This prob lem is in fre quent, but can oc cur some times when the coun ter misses ax les. For ex am ple, as sume a 2 axle, 8 foot axle spac ing, ve hi cle trav el ing 60 mph crosses two road tubes spaced 8 feet apart. The spac - ings and tim ings oc curred as be low: 1) Road Tube #1 hit by first axle at 10:00:00.00000.
