Converter Facts

1. All of our converters provide two pairs of RS-485 signals, a transmit pair and a receive pair.

2. All of our converters operate with two-wire and four-wire devices with easy connecting screw terminals.

3. RS-485 drivers and receivers also support RS-422 signals. RS-485 drivers support 32 loads, RS-422 drivers drive just 7 loads. They have the same signal levels. Use an RS-232 to RS-485 Converter when you need an RS-232 to RS-422 Converter.

4. All of our powered converters come with an AC power adapter.

5. Two-wire devices use one pair of wires for the transmit and receive signals. This means you have to switch the transmitter off when not transmitting to avoid blocking messages from the RS-485 device. Use the MAGIC 485 Converters as they have built-in logic for controlling the transmitter. The other converters use the RS-232 RTS Signal to control the transmitter. The RTS Signal has to be handled by the PC program.

6. RS232 has become the short hand way of searching for RS-232. RS232 to RS485 Converters is the same as RS-232 to RS-485 Converters, RS232 Isolators is the same as RS-232 isolators, and RS232 Signal Trackers is the same as RS-232 Signal Trackers.
