The I/O-transmitter 7181 is designed for serial transmission
of alarm or switch information from or to the PC. Using this
device you can eliminate internal I/O-cards for PC. This
device also reduces the amount of wiring when connected
with 2-wire RS-485 bus. Serial communication settings are
made either using handheld programmer or MekuWin PCsoftware. Transmission of fast switching data is limited
mainly by the baud rate and the application software.
To transmit analog information you can use the transmitter
7100.
