• User's Manual
• 120V, 60 Hz power adapter

This model supplies Optical Isolation & Surge Protection.

Each RS-422/485 port is individually optically isolated with 2000 volt DC optical isolation. The optical protects your PC or notebook from spikes and surges on the RS-422/485 network, by converting the electrical pulse into an optical signal and then changing it back into an electrical pulse. Your computer is well protected, since the surges and spikes cannot cross the optical link.

Each RS-422/485 port is individually protected by surge protector to withstand electrostatic discharge and power surges up to 25KV ESD. Surge suppression on all signals prevent damages caused by lighning and high voltage.

Comes with a USB cable & power supply (120 volt, 60 hz).

The PCI-200L-i is designed for RS232, RS422/485 industrial communications. It supports 2 independent RS232, RS422 or RS485 ports. Each port can be configured separately.

Available modes :
RS232, RS422 full duplex
RS485 full duplex (4 wire)
RS485 half duplex (2 wire) with and without echo.

In RS485 modes applications enable transmission by simply sending data. This is done by ART (Automatic Receive Transmit Control) intelligence. The Transmitter is disabled exactly with the end of the last character sent. No modification is necessary in programs. The common control by RTS is possible for compatibility.

Introduction:

The USB Industrial I/O Adapter is designed to make industrial communication port expeansion quick and simple. Connecting to a USB port on your computer or USB hub, this USB Industrial I/O Adapter instantly adds an industrial multi-electrical interface serial communication port to your system. By taking advantage of the USB bus, this USB Industrial I/O Adapter makes it easier than ever to add a RS-422 or RS-485 serial device to your system with easy plug-and-play and hot plug features.

Plugging the USB Industrial I/O Adapter into the USB port, the adapter is automatically detected and installed. There is no IRQ & COM port conflicts, since the port doesn't require any additional IRQ, DMA or memory on the system. The RS-422/485 port functions as a native Windows COM port, and it is compatible with Windows serial communication applications. Each port is individually configurable.

This USB to Industrial I/O Adapter provides instant connectivity to 422/485 communication devices for factory automation, multi-drop data collection devices, barcode readers, time clocks, scales, data entry terminals, PC to PC long distance communications, ATMs and serial communications in harsh enviornments. This USB to Industrial I/O Adapter provides an industrial solution for applications requiring a single node or multi-drop communications over short and long distances.

Optical Isolation & Surge Protection

Optical isolation and surge protection are supported by the USB-COMi-SI-M.

The RS-422/485 port is optically isolated with 2000 volt DC optical isolation. The optical isolation protects your PC or notebook from spikes and surges on the RS-422/485 network by converting the elctrical pulse into an optical signal and then changing it back to an electical pulse. Your computer is well protected, since the surges and spikes cannot cross the optical link.

The RS-422/485 port is protected by a surge protector to withstand electrostatic discharges and power surges up to 25KV ESD. Surge suppression on all signals prevents damage caused by lightning or high voltages.

This adapter supplies Optical Isolation & Surge Protection.

Each RS-422/485 port is individually optically isolated with 2000 volt DC optical isolation. The optical protects your PC or notebook from spikes and surges on the RS-422/485 network, by converting the electrical pulse into an optical signal and then changing it back into an electrical pulse. Your computer is well protected, since the surges and spikes cannot cross the optical link. Each RS-422/485 port is individually protected by surge protector to withstand electrostatic discharge and power surges up to 25KV ESD. Surge suppression on all signals prevent damages caused by lighning and high voltage.
