PC/104 board with four serial ports

1 July 2015 Computer/Embedded Technology

The Emerald-MM-DIO4M-XT is a PC/104 form factor serial module offering four programmable serial ports. Made by Diamond Systems, the module is based on an ST16C554 quad UART with 16-Byte Tx/Rx FIFOs. Programmable features include serial port protocols, line termination, slew rates, enable/shutdown, base addresses and interrupt status register address.

Suiting a wide variety of rugged and on-vehicle embedded serial I/O application needs, the board also offers 48 programmable digital I/O lines. Configurable features include the digital I/O base address, interrupt level, output mode and voltage level selection. The lines can be set for pull-up / -down resistors in two banks of 24 digital I/O lines each.

The Emerald-MM-DIO4M-XT was designed with harsh applications in mind; as such, it features latching connectors to further improve reliability. Extended temperature operation of -40°C to +85°C is tested and guaranteed, and the module is compatible with MIL-STD-202G shock and vibration specifications.
