Litlhophiso tsa Feme
Net485 e tla beoa ho latela liparamente tse amanang le lehlakore la ho amohela data le fanoeng ke mosebelisi pele e romelloa. Hobane tlhophiso ea paramethara ea Net485 e hloka hore mosebelisi a sebelise thapo e tobileng ea serial (1 ho isa ho 1, 2 ho isa ho 2… 9 ho isa ho 9) e hokahantsoeng lehlakoreng la komporo mme a e hlophise a sebelisa HyperTerminal. Karete ea kantle e hloka hore mosebelisi a tlose mokotla. Ho bona litlhophiso tse tsoetseng pele tsa basebelisi,
Ka kopo ikopanye le tšehetso ea rona ea tekheniki.
Basebelisi ba tloaelehileng ba hloka ho fana ka lintlha tse latelang qetellong ea ho amohela ho k'hamphani ea rona ho etsa litlhophiso tsa feme;

Basebelisi ba ka hokela Net485 ho UPS le moamoheli oa MODBUS kapa PC bakeng sa tlhahlobo.
Litaba tse latelang ke example ea [Modscan] tlhahlobo ea software.
Haeba o hokela Net485 lehlakoreng la PC bakeng sa tlhahlobo, o hloka ho itokisetsa thapo ea hau ea RS485 ho RS232. U ka sheba setšoantšo se latelang bakeng sa mokhoa oa ho hokahanya.
- Matha [Modscan], tobetsa Connection, khetha "PC serial port" e hokahantsoeng le tlhahiso ea Net485, le li-setting tse amanang le Modbus. Joalokaha ho bontšitsoe setšoantšong.
- Khetha rejista ea ho ts'oara 'me u qale aterese ho view data e fumanoeng.
- Sheba lintlha tsa UPS tse emetsoeng ke aterese e lumellanang le aterese e fanoeng file.
