SUNIX, a leading RS-232/422/485 UART solution provider, introduces second generation of RS-422/485 industrial standard universal PCI serial communication board- IPC-P21XX Series. IPC-P21XX Series comes in the selection of 2/4/8/16 ports in choice of RS422/485 with DB9 or DB25 serial connectors and compatible with all major operating systems for industrial applications.
SUNIX IPC-P21XX Series 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/CSTM , 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. |

| 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. For whole board (SUNIX 4-port High Speed RS-232 card), it only costs 0.265W under 921.6Kbps working environment.

| High Performance | ||||||||||||||||||||||||||||||||||||||||||
|
SUNIX Universal PCI Card data transfer rate up to 921.6 Kbps per port, offering the throughput up to 700 Kbps, the highest performance so far, for RS-232 serial communication. SUN1999 UART controller also has built-in hardware and software flow control circuit, preventing data loss. It’s a great solution for commercial and industrial application.

| RS-422 and RS-485 Auto Detect & Switching Technology | ||||||||||||||||||||||||||||||||||||||||||
|
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.

| Surge and Isolation Protection for SI version RS-485 Board | ||||||||||||||||||||||||||||||||||||||||||
|
Surges are high amplitude electrical pulses lasting only several millionths of a second in duration. They can be caused by heavy-duty equipment, power lines, short circuits, or large motors. A surge suppressor has the ability to effectively absorb the high energy in an extremely short period of time, preventing the connected devices from damage. To eliminate this problem, we provide the embedded 500W surge protection for all signals, and it meets IEC61000-4-5 class 2 standards.

| AHDC/CSTM Technology | ||||||||||||||||||||||||||||||||||||||||||
|
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™ will check to see if the bus is idle or not before 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. This is for the CS (carrier sense) part.
