modems, printers, scanners, and other serial devices. Two
models are available. The USB-41 has two RS-232 and two RS-
422 ports, and the USB-42 provides four RS-422 ports. Each
model is housed in a small plastic cabinet.

will connect up to 127 devices and support data rates of 12 Mbps. Many new peripherals developed for
the USB interface will soon be available.
