PXIe Serial Communication Module 8CH

PART NUMBER : DE140501

DE140501 – PXIe RS232/RS422/RS485 Serial Communication Module 8Ch is a PCI eXtension for Instrumentation (PXIe) compatible module offering 8 channels of high-performance RS232/RS422/RS485 programmable asynchronous serial interface.

Overview

The serial channels can be individually programmed to operate as RS232, RS422 or RS485 full duplex/half duplex interface. In addition, programmable termination is provided for the RS422/RS485 interfaces. After power-up all serial I/O lines are in a high impedance state.

Each RS232 channel supports RxD, TxD, RTS, CTS, and GND.
RS422 and RS485 full duplex supports a four-wire interface (RX+, RX-, TX+, TX-) plus ground (GND).
RS485 half-duplex supports a two-wire interface (DX+, DX-) plus ground (GND).

Each channel has 256-byte transmit and receive FIFOs to significantly reduce the overhead required to provide data to and get data from the transmitters and receivers. The FIFO trigger levels are programmable and the baud rate is individually programmable up to 1Mbps for RS232 channels and 20Mbps for RS422/RS485 channels with selectable 250kbps slew limiting. The UART offers readable FIFO levels.

All serial channels use ESD and Surge protected transceivers. ESD protection is up to ±30kV.

Key Features
