The new FlexCom104 communications platform supports Multitech universal socket devices and can carry up to two universal socket compliant modules.

The new FlexCom104 communications platform from Datasound Laboratories supports Multitech universal socket devices and can carry up to two universal socket compliant modules. The unit includes a four-port XR16C854 quad UART providing communications to the two universal sockets, the FV-25 GPS, and one additional serial port. The XR16C854 is an enhanced quad UART supplying 128byte for the transmit and receive FIFOs, transmit and receive FIFO counters and trigger levels, and automatic hardware and software flow control.

The FlexCom104-GPS can be supplied with pin configurations for wireless or wired MultiTech modules.

In order to avoid conflict between wireless mounting holes and wired status pins, the wired status pins are not populated and instead, either two universal socket modules can be populated on the top-side, with one FV-25 GPS soldered to the bottom, or one universal socket can be populated on the top-side, with one space for an FV-25 GPS to be mounted on the top.

The PC/104 bus provides access to a high-speed quad UART.

Two of the UART ports are brought to the serial ports, providing up to 921.6Kbit/s.

The jumper settings on the FlexCom104 provide an easy way to reassign the I/O addresses and IRQs of the UART.

The FlexCom104 can be supplied with each universal socket either hard-wired to a 3.3 or 5V supply voltage or with jumper selectable supply voltages.
