High Performance Serial I/O Functionality
The Emerald-MM-DIO4M-XT is a PC/104 form factor serial module offering 4 programmable serial ports. The module is based on a 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. The EMM-DIO4M-XT fits a wide variety of rugged and on-vehicle embedded serial I/O application needs.
Digital I/O Lines
EMM-DIO4M-XT 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 / pull-down resistors in two banks of 24 digital I/O lines each.
The Emerald-MM-DIO4M-XT was designed with harsh applications in mind including latching connectors to further improve reliability. Extended temperature operation of −40°C to +85°C is tested and guaranteed. The module is compatible with MIL-STD-202G shock and vibration specifications.
Emerald-MM-DIO4M-XT is a programmable PC/104 serial I/O module offering 4 multiprotocol serial ports and 48 digital I/O lines. The serial ports are based on a ST16C554 quad UART with 16-byte TX/RX FIFOs. Each serial port can be independently configured for RS-232, RS-422, or RS-485 protocols, along with programmable 120-ohm line termination. Other programmable serial port features include slew rate, enable / shutdown and base address. All serial ports also feature +/-15KV ESD protection. The serial ports are brought out in pairs to two pin headers with latching connectors for increased isolation and ruggedness. With its wide operating temperature range and high resistance to shock and vibration, the EMMDIO4M-XT fits a wide variety of rugged and on-vehicle embedded serial I/O application needs. EMM-DIO4M-XT also offers 48 programmable digital I/O lines configured as six 8-bit ports. All ports have individual direction control. Ports 0, 1 and 2 offer programmable edge detection with interrupt capability on change of state. Other programmable DIO features include pull-up / pull-down resistors, base address, interrupt level, output mode, and voltage level.
The EMM-DIO4M-XT is compatible with Windows 7/Vista/2000/XP and Linux 2.6. All drivers are shipped with the product.
