Smart switch & harsh environmental protections give you a NEW Experience of RS-422/485 !!

2009/05/20

SUNIX Universal PCI RS-422/485 Cards 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.

Do you know about Optical Isolation Protection ???

The ground loop is a common problem in many industrial environments, especially when ground voltage levels differ between connected devices by a longer transmission line in critical or harsh factory environments. Communication devices connected by long cables may be damaged by the mismatch between ground voltage levels at the two ends of the wire. Optical isolation uses photo cells at both ends of the line to isolate the devices’ sensitive components from this type of electrical damage. SUNIX provides 2.5KV optical isolation for power and signals to eliminate this kind of problem.

What is Surge Protection ???

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 600W surge protection for all signals, and it meets IEC61000-4-5 standards.

RS-422/485 Auto Detect & Switching Design

SUNIX developed a unique technology "Auto Detect and 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.

Low Power Consumption

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.

AHDC/CS™Technology

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.
