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.

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

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.

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

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.

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.

Isolation

DC-to-DC converter provides Power Isolation

Optocoupler component provides Signal Isolation
