Sealevel Systems, represented in Australia by Allied Data Systems , has introduced the optically isolated four port PC/104 serial adapter.
This new board [C4-104.485+I] has 1,500VDC port-to-port isolation and protects systems from ground loops and voltage transients that are common in remote installations and industrial environments.
For maximum versatility without opening the PC/104 stack, each port is software configurable for full-duplex (4-Wire) RS-422 or RS-485.
Half duplex (2-Wire) RS-485 mode is also supported. The RS-485 enable signal is automatically controlled providing high level of data integrity and eliminating any risk of bus contention and data corruption.
Jumpers on the board allow suppressing ECHO on a per-port basis. Designed to meet the core needs of PC/104 applications requiring high reliability, small size and long term availability, the C4-104.485+I is an ideal choice for a variety of military and industrial applications.
The C4-104.485+I includes an Oxford 16954 UART with 128-byte transmit and receive FIFOs for fast, error-free communications up to 921.6K bps.
The UART includes support for 9-bit protocol and the clock prescaler, coupled with a 14.7456 oscillator, provides high resolution for achieving all standard and many non-standard baud rates.
Included with the board is Sealevel Systems' SeaCOM suite of drivers for Windows 98/ME/NT/2000/XP/Vista operating systems.
WinSSD, a full-featured diagnostic application providing powerful testing and troubleshooting capabilities, is included to assist in application development and testing.
Use WinSSD for BERT (Bit Error Rate Testing), throughput monitoring, loopback tests, and transmitting test pattern messages.
SeaCOM also includes drivers, utilities, application notes, and technical details to simplify installations in Linux, QNX, and DOS.
