1. 1 VXC Communication Cards Jun. 03, 2009 Gary Lin ICP DAS Co., Ltd. -- Multiport Serial Cards -- (RS-232/422/485)

2. 2 Agenda VXC Card Features Product Showcase Appendix

3. 3 Universal PCI Card

4. 4 Communication Speed (Baud Rate) VXC card supports bard rate up to 115,200 bps. Also works with 460,800 bps when communication on a very short distance. Does not work with 921,600 bps since the protection components limitation. The related conditions includes : quality of cable, distance and environment (noise)… etc.

5. 5 Selection for RS-485 Master/Slave RS-485 requires pull-high/low bus signals RS-485 requires one host/device to pull high/low the bus signals. Many device pull the signals at the same time may cause communication problem. Master/Slave selection on VXC Card There are jumpers on the VXC cards for users to configure the RS-485 port as master (pull-high/low) or slave. That would be better to choose a suitable configuration depending on your communication system. Default: Master (Pull)

6. 6 Self-Tuner for RS-485 RS-485 Requires Direction Control 2-Wire RS-485 is designed for half-duplex communication, and users have to consider the sending/receiving issue. Other company may use RTS signal to control the RS-485 direction. This may have timing issue and cause communication problems. Self-Tuner Controls the RS-485 Direction Automatically ICP DAS provides Self-Tuner ASIC that automatically control the RS-485 direction, baud rate and data format changes. It is fully controlled by hardware, so no more direction control issue for users. This provides a stability communication and speeding your system development.

7. 7 COM-Selector 8-Bit DIP-Switch, defines 0 ~ 255 Special design from ICP DAS. 0 (All Off): Auto-select COM Port Number Selecting by Windows system, may have a dynamic number. Automation System may not get the correct COM port number and cause system failure. 1 ~ 255: COM1 ~ COM255 Selected by user, fixed COM port number. It’s recommended to reserve (don’t use) COM1 ~ COM4 for other PnP COM Ports. This prevents confliction. Users have to make sure the selected COM port number is available, or the port will not work. Example: COM-Selector set to 0x05 2-Port Card: COM5, COM6 4-Port Card: COM5, COM6, COM7, COM8 Special Design from ICP DAS

8. 8 Up to 128-byte Hardware FIFO Standard 16C550 chip provides 16-byte hardware FIFO The new VXC cards from ICP DAS provides 128-byte hardware FIFO for each port 128-byte hardware FIFO is useful when communication in high speed or in a heavy loading system.

9. 9 ESD Protection TVS (TRANSIENT VOLTAGE SUPPRESSOR) diode protects components by providing a transient current path to the frame ground when there is high voltage noises.

10. 10 Isolation DC-to-DC converter provides Power Isolation Optocoupler component provides Signal Isolation
