Multiport Serial Cards Extending the Serial Networks

SUNIX Serial Communication Boards family provides an array of PCI Express, PCI, PCI/104 and PC/104 interfaces to meet your serial port expansion needs. Multi-port Serial Communication Board comes in the selection of 2/4/8/16 ports in choice of RS-232, RS-422/485 or 3-in-1 combo with DB9 or DB25 serial connectors and compatible with all major operating systems for industrial applications. The Serial Boards series is best suited for applications where the CPU is able to devote some of its resources to handling computations or to real time applications that require short latency intervals.

SUNIX boards offers “Auto Detect and Switching RS-422/485” technology, which can automatically detects the state of RS-422 full duplex or RS-485 half duplex and control the data transmitter and receiver wires at the same port without any jumper setting. This design gives users the convenience and hassle free option to change the communication mode settings. SUNIX has also developed a hardware technology called Auto Hardware Direction Control/Carrier Sense (AHDC/CS™), which is to control the direction of signals (ON or OFF) automatically in 2-wire RS-485 mode.

This can precisely control the transmitting signals during the start and end of data transmission.
