Omschrijving
Universele converter van RS232 naar RS422/485 (2 en 4 draads)
30-4WSD9R
The 4WSD9R Universal Converter is a port-powered or externally powered two-channel RS-232 to RS-422/RS-485 converter.
It converts TD and RD RS-232 lines to balanced RS-422 or RS-485 signals. RS-485 is an enhanced version of the RS-422 standard, allowing multiple drivers and receivers on a two-wire system.
The unit is powered from the RS232 data and handshake lines whether the lines are high or low. Or, if there is not enough power on the port, it can be powered by an external +12VDC 100mA supply.
The 4WSD9R has DB-9 female connectors on both the RS-232 side and the RS-485 side. The RS-232 connector is configured as DCE (like a modem).
