Which Sealevel asynchronous serial adapters support isochronous communication mode?
Most of our bus based adapters, including PCI Express, PCI, PCMCIA, PC/104 and ISA, can be used. The adapter must have a 16C950 UART installed and support the Ring Indicator (RI) signal. The 16C950 UART is necessary to allow the SeaCOM driver to put the adapter into isochronous mode. Ring Indicator accepts the external clock signal which is required to operate in isochronous mode.
Order the serial adapter with an -SN suffix, which designates the 16C950 UART. Refer to the pin out diagram of the appropriate product manual for the presence of the Ring Indicator signal.
