  3. Universal PCI Card 3

  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. 4

  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) 5

  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. 6

  7. Special Design from ICP DAS COM-Selector • 8-Bit DIP-Switch, defines 0 ~ 255Special design from ICP DAS. • 0 (All Off): Auto-select COM Port NumberSelecting 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 ~ COM255Selected 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 0x052-Port Card: COM5, COM64-Port Card: COM5, COM6, COM7, COM8 7

  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. 8

  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. 9

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