PC/104 Utility Board Provides 60-V Optical Isolation

The Model 104-ICOM-2S dual-port PC/104 utility board features 60-V optical isolation. The two serial ports are based on the 16C550 UART with a 16-byte FIFO, useful for high-speed communication and embedded Windows operating systems. The ports are available via two DB9 male connectors with jack screws, eliminating vibration issues in harsh environments. Each port's protocol (RS-232 or RS-485) is selected by jumpers on the board. Two- and four-wire communications are possible, including four-wire RS-485 communication. In Windows operating systems, the ports install as standard COM ports and employ Windows drivers. Support is also offered for Linux operating systems. The board may be installed in any standard PC/104 motherboard or stack. Versions are available for use in commercial (0°C to 60°C) and industrial (−30°C to 85°C) environments. The Model 104-ICOM-2S costs $229 each, including software.
