The AIM104-SER4 is an 8-bit PC/104 module providing four channels of RS232 serial ports. It is based on the 85230™ Enhanced Serial Communications Controller and is capable of RS232 signaling standards. Every channel can be independently configured for asynchronous and synchronous protocols, baud rate and signaling standard. High speed communications can be achieved up to 57.6kBaud (asynchronous) or 921kBaud (synchronously).
