Meron namang USB to RS232 cable ang cdr-king mga p150 ang bili ko and i tried it to communicate with rs232 equipment to my usb laptop ok naman, prolific din ang chipset.

Di lang ako sigurado kung gagana sa rs232 na PIC programmers.

I have comm with it using 3 wire scheme (tx,rx,s.gnd) ng rs232 and its functioning well.

Bumili rin ako ng ganito para sa Slimboard Zilog Microcontroller. Wala kasi serial port laptop ko http://www.cdrking.com/local/products/index.php?action=&temp=2&typeno=8176890-373780-839110596-1439562&prod=PS2/Serial%20Cables&prodcode=6171348-677459-088753700-0409530  . Ang problema ang CD sa loob ng binili kong serial cable to usb sa CDRKING di ko malaman saan yung installer ng driver... Wala namang driver download nun sa CDRKING na website. Di madetect ng laptop ko yung usb to serial cable ko. PAHELP!! :(

ilang serial-usb converter lang naman yan...

yung saakin, di ko din alam kung anong tamang driver dun. pero patsamba-tsamba, nalaman ko na HL-340. yung iba ang nakukuha PL2303... dati nga sa pagkakaalam ko, may FTDI sila.

so try mo nalang lahat.

PL2303 'yung mga data cable., CH340 naman 'yung USB to RS232. merong pang-Samsung na nasa connector mismo 'yung PL2303. ;D

sir ask ko lang po...

Yung project ko na Serial LCD using 16f84A i interface ko na po sa PC kaso kailangan ko gumamit ng serial to ttl...now instead na mag add ako ng MAX232,, pede ba na itong cable na lang? thanks...


Serial LCD ko kasi almost done na... medyo me babaguhin na lang sa code... now para ma connect ko sya sa PC kailangan ng SERIAL -TTL converter... e baka makatipid pag yan ang gagamitin ko..

thanks po

madalas mababa ang voltages niyan pero 'di pa siya TTL. pwedeng gumamit ng transistor level translator or MAX232.
