Frequently Asked Questions
What power supply voltage does this converter require?
The converter accepts a DC input from 3.3V to 5V and includes built-in over-voltage and reverse-polarity protection to ensure safe operation.
How does the galvanic isolation work?
A unibody isolated power design separates the TTL side from the RS232 side, preventing ground loops and protecting equipment from surges or lightning strikes.
Can this module extend RS232 communication over long distances?
Yes. By converting TTL signals to RS232 levels with surge protection and isolation, you can reliably transmit data over standard RS232 cabling for distances up to 15 meters or more, depending on cable quality and baud rate.
