PCL-745B

PCL-745B

2-port RS-422/485 Cards with 3000 VDC isolation protection
		Main Features Two independent RS-422/485 serial ports Provides 3000 VDC isolation 16C550 UARTs with on-chip 16-byte FIFO Transmission speeds up to 921.6 kbps I/O address and interrupt selectable Wide IRQ selection: 3, 4, 5, 6, 7, 9, 10, 11, 12 or 15 Supports 2 wire or 4 wire operation Supports Tx, Rx, RTS, and CTS signals Automatic RS-485 data flow control or RTS control Termination resistors jumper enable/disable Space reserved for optional surge protection on data lines Supports Windows® 98/2000/XP, Linux®

Introduction
The PCL-745 series card provides two RS-422/485 serial ports.Each port utilizes a 16C550 UART with an on-chip 16-byte FIFO buffer for reliable, high-speed serial I/O. The UART buffer divides data into 16-byte packets before sending them onto the bus. This drastically reduces the CPU load and avoids data loss due to failure to respond to the interrupt request in time. The UART is especially useful for high speed serial I/O under Windows. The PCL-745B card differs from the PCL-743B card in that the former uses on-board optical isolators to protect your PC and equipment against damages from ground loops, increasing system reliability in harsh environments.

To further increase reliability, the PCL-745S offers surge protection technology, protecting your system from abrupt high voltage surges (up to 2500 V) such as those caused by lightning.

4-port High-speed RS-422/485 Communication Card
		Main Features Four or eight RS-232 or RS-422/485 serial ports Transmission speeds up to 921.6 kbps Independent/shared IRQ settings between each of the 4 serial ports Wide IRQ selection: 3, 4, 5, 6, 7, 9, 10, 11, 12 or 15 Supports COM1, COM2, COM3, and COM4 Provides 1000 VDC isolation (PCL-846 only) Provides 2000 VDC EFT Surge Protection (PCL-846B only) Provides 3000 VDC EFT Surge Protection(PCL-849B, PCL-849+, PCL-858B) Space reserved for termination resistors Supports 2 wire or 4 wire operation Automatic RS-485 data flow control or RTS control Supports Windows® 98/ME/2000/XP, Linux Powerful and easy-to-use utility (ICOM Tools)

Introduction
PCL-800 series communication card provides reliable, high-speed serial communication. The unique shared interrupt can be set to most common (extended) AT interrupts. This simplifies programming, speeds up interrupt processing and frees up interrupts for other devices. PCL-800 series cards also provide EFT surge or isolation protection to prevent your PC and equipment against damage from ground loops, increasing system reliability in harsh environments or abrupt high voltage surges such as those caused by lightning during thunderstorms.
