APCI-7xxx
1 to 8-port serial interface, RS232, RS422, RS485,
20 mA CL, modular mounting through modules
APCI-7300-3 – 1-port serial interface
APCI-7420-3 – 2-port serial interface
APCI-7500-3 – 4-port serial interface
APCI-7800-3 – 8-port serial interface
RS232, RS422, RS485, 20 mA Current Loop
Free mode configuration for each port
through MX modules
With/without optical isolation 1000 V
128-byte FIFO buffer for each port
16C950 UART downward compatible
PCI 3.3 V or 5 V
The APCI-7xxx-3 communication boards are congured by
inserting MX modules which the board identies auto-
matically. The 1- to 8-port serial interfaces APCI-7xxx-3 can
be used as universal PCI boards in 3.3 V or in 5 V systems,
and in PCI or PCI-X systems. The serial interfaces can be
congured through modules in the following modes:
RS232, RS422, RS485 (with or without optical isolation)
and 20 mA current loop (with optical isolation).
The MX modules with optical isolation allow a protection
up to 1000 V for the use in noisy environments where
earth loops can occur. The I/O lines are protected against
short-circuits, fast transients, electrostatic discharge and
high-frequency EMI. The interface is supported through a
128-byte FIFO buffer for sending and receiving data and
guarantees reliable operation at high transfer rates.
