Information & Support
Q: I am using an ATA-66 (or 100) hard drive, how can I know that ATA-66
function is started?
A:
You need to use the 80-pin ATA-66 IDE flat cable to have this function ready.
During POST, you can see ATA-66 (or 100) message while hard drive is being
detected. Besides, after Microsoft series OS installation successfully, you must
install ATA-66/100 driver, then the function can be active.
Q: After changing setting of serial port from RS-232 to RS-485, why 485 function
still cannot work normally?
A:
Cable must connect to same definition of pins. For example, there are only two
pins in RS-485, which are DATA – and DATA +. Its connection must be “DATA –
connects to DATA –“, and “DATA + connects to DATA +”. Otherwise, RS-485
won’t be able to transfer its data. Besides, you need to program communication of
RS-485 by yourself.
