Easily add additional serial ports to your system. The Multi-2C/LPCI is equipped with SystemBase’s powerful semiconductor – SB16C1052PCI, to deliver maximum performance up to 921.6Kbps with the world’s leading 256 byte FIFO preventing overrun errors. Combine that with the need for fewer components and you get costeffective and reliable connections to your serial devices. The Multiport boards support most Windows and Linux operating systems and include 15,000 volt surge suppression eliminating blown ports. The Multi-2C/LPCI has two on-board DB9 connectors and is available in two models, RS232 and RS422/RS485 (COMBO). These boards are ideal for POS, hospitality, factory automation and building automation applications.

Power to the port

The Multi-2C/LPCI is configurable to deliver +5 or +12 volt power to pin 9 to power external devices. This functionality is ideal for connecting low power devices such as barcode readers and receipt printers eliminating the need for an external power supply.

Slew-Rate Limit Control

The Multi-2C/LPCI COMBO is equipped with Slew Rate limit control and when enabled it minimizes EMI emissions which may cause data transmission errors. When Slew Rate is used maximum communication speed is 250Kbps. This functionality is recommended in many medical applications.
