ESCRIPTION
Micronix PV-interfaces let you customise your system and optimise a combination of RS232, RS422 or RS485
data transmission. All signals are surge protected for industrial applications. The PV-modules plug into any
standard PC/104 bus interface.
With the advanced 16C550 UART or highspeed 16C650 UART (-H versions) with 16-byte FIFO, your
industrial PC can communicate with other computers or peripherals at high speeds.
Compatible to standard serial interfaces supported by DOS and Windows operating systems. Four ribbon
cables with DB-9 connectors are optional.
Non-stackthrough or stackthrough (S-versions) connectors are available.
