| Introduction | | SUNIX Serial Communication Boards family provides an array of PCI
Express,PCI, PCI/104 and interfaces to meet your serial port
expansion needs.Multi-port Serial Communication Board comes in the
selection of 8 ports inchoice of RS-232, RS422/485 or 3-in-1 combo
with DB9 or DB25 serial connectorsand compatible with all major
operating systems for industrial applications. TheSerial Boards
series is best suited for applications where the CPU is able
todevote some of its resources to handling computations or to real
timeapplications that require short latency intervals. SUNIX boards
offers"AutoDetect and Switching RS-422/485" technology, which can
automatically detects thestate of RS-422 full duplex or RS-485 half
duplex and control the datatransmitter and receiver wires at the
same port without any jumper setting. Thisdesign gives users the
convenience and hassle free option to change thecommunication mode
settings. SUNIX has also developed a hardware technologycalled Auto
Hardware Direction Control/Carrier Sense (AHDC/CS), which is
tocontrol the direction of signals (ON or OFF) automatically in
2-wire RS-485mode. This can precisely control the transmitting
signals during the start andend of data transmission. | |
| | Features | Supports 8 independent RS-422/RS-485 serial ports.
Serial communication speeds up to 921.6Kbps.
SUNIX AHDC/CS technology for RS-485 2-wire signal direction
control.
RS-422 and RS-485 Auto Detect and Switching technology.
Built-in 64 byte hardware FIFO & 128K byte DMA software FIFO
for high speed and reliable communications.
Easy to install- no DIP switches or jumpers to set.
Surge and Isolation protection for SI version.
Supports DOS, Linux, Unix, Microsoft 2000, XP, 2003 and Vista.
Ready for the Intel and AMD 32/64-bit CPU and operation system. | |
