Amanothi:
1. Lapho ephezulu, lo mphumela ukhombisa iphutha le-laser lohlobo oluthile. Okuphansi kukhombisa ukusebenza okujwayelekile. Futhi kufanele idonswe nge-4.7 - 10k Resistoor on the Host Board.
2. I-TX Khubaza ukufakwa okusetshenziselwa ukuvala ukuphuma kwe-transmitter akhipha. Kudonswa ngaphakathi kwemodyuli nge-4.7 - 10k Resistor. Izifundazwe zalo yilezi:
Okuphansi (0 - 0.8v): Transmitter on (> 0.8, <2.0V): AKUFUNI
I-High (2.0V ~ VCC + 0.3V): I-Transmitter ikhutshaziwe i-Open: Transmitter ikhutshaziwe
3. Mod-def 0,1,2. Lezi izikhonkwane zencazelo ye-module. Kufanele zidonswe nge-4.7k - 10k-Shess Resistor ebhodini elisingathi. I-voltage yokudonsela phezulu izoba phakathi kwe-2.0V ~ VCC + 0.3V.
I-Mod-def 0 isuswe yimodyuli ukukhombisa ukuthi imodyuli ikhona
I-Mod-def 1 ingumugqa wewashi we-wire serial interface ye-id ye-serial
I-Mod-def 2 umugqa wedatha we-wire serial interface ye-id ye-serial
4. Lapho ephezulu, lokhu kukhipha kukhombisa ukulahleka kwesiginali (los). Okuphansi kukhombisa ukusebenza okujwayelekile.
I-5. I-RD +/-: Lokhu kungukuphuma kokwehlukahluka okuhlukile. Ziyi-ac ehlanganisiwe eyi-100 ω ezihlukile okufanele zinqanyulwe nge-100ω (ezehlukene) kuma-sierdes omsebenzisi. Ukuhlangana kwe-AC kwenziwa ngaphakathi kwemodyuli futhi ngakho-ke akudingeki ebhodini lokusingathwa.
6. I-TD +/-: Lokhu kungukufakwa kokudluliselwa kwe-transmitter. Ziyimigqa ehlanganisiwe ye-AC Ukuhlangana kwe-AC kwenziwa ngaphakathi kwemodyuli futhi ngakho-ke akudingeki ebhodini lokusingathwa.
