## Long description

The EXSYS EX-45354 internal serial interface card is a reliable hardware solution designed to provide stable wired serial connectivity via a PCIe host interface. Featuring RS-422 and RS-485 serial outputs, this expansion card is built to handle robust data communication in various professional and industrial environments. It measures 192 mm in width and 66 mm in depth, with a weight of 500 grams, ensuring a standard fit for compatible computer systems. Certified with CE and FCC standards, the card meets recognized regulatory requirements for quality and safety.
Advantages
The interface card offers high flexibility through selectable signal modes including 4-wire RS-422 full-duplex and 2-wire RS-485 half-duplex configurations. Integration is supported by a FIFO buffer with 16C950 and 128 bytes to help manage data flow efficiently. System integration is further streamlined with BIOS-managed I/O addresses and interrupt settings featuring IRQ sharing capabilities. Additionally, the inclusion of an enable and disable terminator for 120 Ohm resistance helps maintain signal integrity across longer cable runs.
Suitable for
Connecting industrial automation machinery
Integrating legacy serial devices into modern PC systems
Setting up reliable wired data communication networks
Managing secure serial data transfer in professional workstations
When it may not be suitable
This product may not be appropriate for standard consumer desktop setups that lack an available PCIe slot or do not require specialized RS-422 or RS-485 serial connections. It is also unsuitable for systems requiring wireless connectivity or interfaces other than serial ports.
