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.

RECAUTIONS TO
ESD
Please note, that the Micronix PV modules must be handled with respect to ESD (Electrostatic Discharge).
Electrostatic Discharge to the PV modules must be avoided.
Before removing the module from the protection bag, the user must be discharged using a grounded wrist
ribbon.

ETTING THE
I/O
A
DDRESS
The I/O address for channel A through D is set by the corresponding rotary-switch.
The individual positions are printed on the PCB.

UMBER
(I
NDIVIDUALLY
)
The IRQ number for channel A through D, is set by the corresponding pin column array.
The individual positions are printed on the PCB.

S
ETTING THE
B
AUD RATE
The baud rate is set by the software application. Each port is compatible to a normal PC COM-port and should
be accessed accordingly. Operating systems and standard software applications have utilities for that.
For more sophisticated programming and specific control of handshake signals, please refer to a 16C550
manual. This manual can be ordered from a National Semiconductor representative.
