I have two THVD1520DR connected to each other and with their 120 Ohm resistors at the ends. The problem I have is that the data I send is not received completely, that is, if I send a string of 8 bytes I only receive…
Part Number: THVD1520 Tool/software: Hi Team,
we are using THVD1520 to connect our devices using RS485. the requirement is 3000 feet @ 115200 bps.
do I need send some preamble bytes or sync bytes before I send out the real packet on the RS485 bus…
Part Number: THVD1520 Other Parts Discussed in Thread: THVD1426 , Tool/software: Dear Team,
Kindly recommend a circuit to enable automatic direction switching for Transmit and receive.
Also, do I need to pull up the Ro pin, and the DE/RE pin be…
Part Number: THVD1520 Tool/software: Hi team,
There have several OPNs for THVD1520. I would like to check with you what is the difference and how should we select different OPN?
Thanks!
