Detailed Product Description

4 ports RS-422 / 485 PCI/104

SUNIX IPC-B2104, industrial standard PCI/104 serial communication card, allows users to expand four RS-422/485 ports on PC-based system. It is compatible with PCI/104 BUS specifications, allowing it to be installed in virtually any embedded PC-based systems. Each serial port achieves data rates up to 921.6 Kbps and utilizes 16C950 UART with an on-chip 128-bytes hardware FIFO buffer for reliable, high-speed serial I/O. With SUNIX patented Auto-Switching RS-422/485 and RS-485 AHDC™ technology, user can easily manage different serial interfaces selection and RS-485 signal direction control. Under RS-485 mode, the board can connect up to 31 daisy-chained RS-485 devices within a range of 1.2 km. SUNIX serial board supports a wide variety of operating systems, including Windows, Linux, DOS, and UNIX. It is the best serial communicating solution for industrial and harsh environment applications.

Tech Forum:
PCI-104 Tutorial:
PCI-104 is a PCI-only architecture PCI 32-bit bus running 33MHz that accommodates the advances of high-speed PCI devices in a small rugged form factor for embedded applications. With the publication of the PCI-104 standard in 2003, this bus architecture was available on a small, rugged form factor which has since become an industry standard. PCI-104 adds additional modules using stack-through connectors. This has two advantages: it reduces the system size and it makes the system more rugged so that it can better withstand shocks and vibrations.

RS-422/485 Auto Detect & Switching Design:
SUNIX developed a unique technology "Auto Detect & Switching RS-422/485, which can automatically detect the state of RS-422 full duplex or RS-485 half duplex and control the data transmitting and receiving wires at the same port without any jumper settings. This design gives users the convenience to change the communication mode setting without any system shut downs.

RS-485 ACS™ Technology:
Auto Carrier Sense (ACS™) technology is the data flow control under RS-485 half duplex (one-way traffic) communicating. It manages data flow between computers or devices or between nodes in a RS-485 network, so that the data can be handled at an efficient pace.

Auto Carrier Sense (ACS™) technology will check the status of RS-485 communication bus. If the bus is idle, it starts transmission. If the bus is not idle (some data flows in the bus), then it will postpone the transmission of UART until the bus is idle. Due to the reduction of TX/RX packet conflicting on RS-485 one-way traffic bus, it will enhance better system performance and RS-485 communication ability. SUNIX recommend enabling this feature.

Since RS-485 is bidirectional which means the driver is turned on only when it needs to transmit some data, otherwise it is floating. SUNIX developed a new design to control the direction of driver (On or off) automatically which is called Auto Hardware Direction Control/Carrier Sense. AHDC/CS™ works on the same principle and only turns on the driver when UART needs to transmits some data; but the advantage is that AHDC/CS™.

Auto Hardware Direction Control (AHDC™) technology makes it easier to manage 2-wire RS-485 half-duplex communications, eliminating the need for software interference. User does not necessary to write extra code for Windows applications to control the half-duplex protocol. Auto Hardware Direction Control (AHDC™) technology is the key feature of SUNIX UART, and this function is default enabling.

Ultra Low Power Consumption:
Low power consumption is always a large part of the needs expressed by customers. Recently, low power consumption has become essential not only for system development but also for environmental reasons, and in fact low power consumption has become an ever larger part of the needs expressed by customers. SUNIX has pursued this issue via various approaches, as it seeks to provide special cell-bases ASICs that meet today’s challenging needs for lower power consumption during active and standby modes. According to our typical test result, SUNIX UART controller, SUN1999 costs 0.033W (3.3V@0.01A) power consumption under full-loading working condition.
