Heren,

Vragen over de producten kan hier: http://domoticaforum.eu/topic.asp?TOPIC_ID=2452
Nog even een duidelijker overzicht: http://80.69.78.207/rfid.xls
Idee-en met elkaar uitwisselen kan hier: http://domoticaforum.eu/topic.asp?TOPIC_ID=2461

Deze pagina wil ik STRIKT alleen gebruiken om de statussen weer te geven van openstaande vragen naar de leverancier, dan wel de bestellijst.

Graag bestelling doorgeven via PM!!! Vragen waarvan het antwoord op dit forum niet te vinden is, stel ze hier, dan communiceer ik het door met de leverancier en meldt het antwoord ook in deze topic.

RFID transmitters & receivers BESTEL EN STATPAGINA

Vragen naar de leverancier:

<b>Q1: Is there a USB version of the RF9315R? If so what's the price?</b>
A1: The USB verison for RF9315R is working fine. The retail price will be US$16 higher than USB version for RF8135R. For distributor, it will be US$11 higher.

<b>Q2: Does the USB 2 serial PCB be available for the other RS232 RFID receivers ? Is so, what is the cost?</b>
A2: Some of the USB/Serial convertor the output power is not high enough for our receiver, therefore we cannot sell the USB/Serail convertor alone. If you buy USB/Serial convertor from other store, some receiver will work but some will not.

<b>Q3: Does The RF9315R also receive the other transmitters (like the 40 meters fi) ?</b>
A3: RF9315R the function is exactly the same as RF8315R with RSSI output. RF9315R can only handle 80 tags at one time while RF8315R and handle 160 tags at one time.

<b>Q4: How does the RF9315R measure RSSI? What are the differences in value if we use a 8 meter or 40 meter transmitter?</b>
A4: RSSI is the RF power receives when the tag ID is rececived. The RF power depends on the operating battery voltage, the efficient of the transmitter, therefore it cannot tell the RSSI value difference when 2 same or not the same tags are in the same distnace away from the receiver. The RSSI can only be used to determine whether the object is moving toward or away from the receiver. May be you can have some bright idea on how to use it.

<b>Q5: Can the range be extended from 8m to 14m by putting a 9" antenna on all these modules: RF8315T, RF8315T-s, RF8315T-x, RF8315T-xl, RF8315T-sc? Or just the RF8315T?</b>
A5: For 433 version, you don't need to change anything and can achieve 14 meter. If you want to further increase the range, you can find some information from 2 forum in US. Someone said that he can achieve 1.5km. I will forward the link to you later today.

<b>Q6: Is the case that comes with the RF8315T-sc the 'RF8315T Enclosure' or is it a smaller box?</b>
A6: RF8315T enclosure IS NOT the same as RF8315T-s. RF8315T-s is much smaller.

<b>Q7: Are batteries included with the transmitters?</b>
A7: Yes

<b>Q8: Can extra batteries be ordered? If so, what are the costs?</b>
A8: US$1 for 5 pcs

<b>Q9: Because you'd send me links to homeseer website, we are wondering if you know if the 9xxx receiver will work with the CheaperRFID plugin or other? We ask because the RSSI is added to the response connected with the computer. If you don't know, any idea if you could send a sample so we can test it?</b>
A9: No.It will not work as 9xxx receiver will report RSSI as well.

Bestellingen:

<b>Note1: Graag meld ik nog wel even dat mensen die een 40 meter transmitter bestellen en deze voor de auto wilen gebruiken beter de -x variant kunnen nemen, zodat je deze op de accu kunt aansluiten ipv met batterijen te gaan werken.</b>

<b>Note2: De RF9315R ondersteunt RSSI, maar de plugin van Homeseer werkt hier niet mee. Omdat de receiving bytes ook de RSSI meestuurt, vraag ik mij af of de plugin standaard werkt (en dus niet over zijn nek gaat). Het moet zeker hier met de diverse programmeurs op te lossen zijn.</b>

<b>Note3: De knoopcelbatterijen schijnen een negatief effect te hebben op het bereik doordat deze niet goed tegen lage temperaturen kunnen (http://forums.homeseer.com/showthread.php?t=134069). In de auto doe je er dus verstandig aan om zelf AA batterijen toe te passen of de variant te kiezen die je direct op de accu kunt aansluiten.</b>
