Multi-2/PCI is a serial communication card built around SB16C1052PCI, SystemBase's own high-performance semiconductor. The SB16C1052PCI is a PCI bus UART that integrates one of the largest transmit/receive FIFOs available, at 256 bytes, delivering overrun-free performance even at a communication speed of 921.6Kbps.
It also has a range of built-in functions essential for serial communication, so no additional components are needed and the circuit can be built with a minimal parts count, resulting in high reliability. Multi-2/PCI is available in two models supporting RS232 and RS422/RS485 (Combo) interfaces, and is used across a wide range of applications, including office automation and factory automation.
Through a jumper setting, Multi-2/PCI can supply +5V or +12V externally via pin 9 of its DB9 connector, in place of the RI signal line. This approach, pioneered by SystemBase, makes it simple to power devices such as barcode readers directly from the card. This removes the need for a separate power adapter, reducing additional cost while providing a cleaner installation and significant maintenance benefits.
Multi-2/PCI provides an Auto Toggling function for RS422/RS485 communication. This feature helps prevent electrical conflicts between output signals when configuring an RS422 multi-drop network or operating on an RS485 network. Since this feature is supported in both hardware and software, it can be enabled with a simple setting in the setup screen.
Multi-2/PCI provides a Slew Rate Limiting function for RS422/RS485 interface communication. By suppressing the electromagnetic emissions generated during data communication, it delivers a stable communication environment in EMI-sensitive settings such as medical equipment and research labs. When this feature is enabled, the maximum communication speed is limited to 250Kbps.
