can I use Hyperterminal to communicate with VMB1RS and send command to velvus?
or can I use other hardware with 232 interface to send command to velbus?
I mean use other hardware with 232 interface also built in ours firmware to communicate with velbus to send command according to Velbus protocol, is it same result with velbus software?
While Hyperterminal van connect to the Velbus, Hyperterminal can only send what you type - ASCII characters - which is not enough to communicate with the Velbus.
Hardware alone is not enough to communicate with the Velbus, you need software. Our VelbusLink software does what you need, download it here.
