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
