User Manual
Note: This equipment has been tested and found to comply with the limits
for a Class B digital device, pursuant to Part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses
and can radiate radio frequency energy, and if not installed and used in
accordance with the instruction manual, may cause interference to radio
communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct
the interference by one or more of the following measures:
Reorient or relocate the receiving antenna;
Increase the separation between the equipment and receiver;
Connect the equipment into an outlet on a circuit different from that which
the receiver is connected;
Consult the dealer or an experienced radio/television technician for help.
￭ Introduction
The IC-424AP is a PCI bus card that supports four independent RS-422 or RS-485 serial
ports. It is ideal for various industrial communication and automation applications.
Each port utilizes 128K FIFO memory and is able to control devices in a multi-drop mode.
Furthermore, built-in isolation and surge functionality can protect your equipment and
controller from being damaged by lightning or high voltage damage.
The IC-424AP supports both 3.3 and 5 voltages and can be used in eithe r a 32 or 64 bit
PCI slot. It can be installed in virtually any computer. Setup is easy since it is plug and play
compatible, users do not need to set jumpers for I/O addresses or interrupt locations.
Auto RTS Signal Control technology is integrated into the card providing the best way to
send and receive half-duplex RS-485 transmissions without software or writing extra code.
In addition, RS-422 and RS-485 auto identify and switch technology makes it more
convenient for users to change between RS-422 and RS-485 peripherals.
￭ Features
Fully compliable with PCI Specification Version 2.2 standard
Supports both 64-bit & 32-bit PCI Bus and 3.3V &5V connector keys
High speed serial ports support baud rates up to 921.6Kbps
128K FIFO can reduce CPU loading, interrupting and improving system performance
dramatically
Auto Identify and Switch RS-422/485 technology makes it more convenient to
manage devices without jumpers or switch settings
Auto RTS Signal Control technology can identify the status of data transceiver or
receiver and send RTS signal automatically, instead of using software to control the
transmitter.
An optional function of optical isolation (2.5KV) can prevent lightning or high potential
voltage damage. The embedded surge protection (600W) for all signals are available
in this series.
High speed 16C650 compatible communication controller with SUN1889 single chip
hardware flow control to guarantee no data loss and best technical support.
Plug and Play, I/O address and IRQ assigned by BIOS.
Support Microsoft Windows 3.x, 9x, NT, 2000, XP, 2003, DOS, and Linux.
