Description

The PCM-COM8 is an 8-channel PC/104-compatible serial module. It is well suited for embedded applications requiring a large number of serial I/O ports. Each channel supports RS-232, RS-485, and RS-422 electrical levels to interface to a wide variety of serial communications devices such as modems, data collection equipment, and distributed I/O terminals. The PCM-COM8 will operate over the full industrial temperature range of -40° to +85° Celsius. Features Eight independent COM channels Two 16C554-compatible quad UARTs 128-byte TX and RX receive FIFOs on each channel RS-232, RS-485, and RS-422 electrical interface levels on all channels All outputs short circuit protected Modem control signals: CTS, RTS, DSR, DTR, RI, and DCD on each channel Programmable serial interface characteristics for each channel: 5-, 6-, 7-, or 8-bit character lengths Even, odd, or no parity generation and checking 1,1.5, or 2 stop bits Local internal loopback for diagnostics Industrial -40° to +85°C operational temperature
