Introduction
Thank you for purchasing the LINDY USB to 4 Port Serial Converter. This device provides multiple external
RS-232 connections to your PC. It features four standard 9 Way D Male connectors for connecting your
serial devices.
The unit's compact size makes it ideal for use with notebooks or as an alternative to installing an internal
serial card in your desktop PC. It supports most standard RS-232 serial devices such as modems, ISDN
terminal adaptors, PDAs, barcode readers, label printers, EPOS devices etc.
Installation is easy with no changes to IRQ, I/O Address or DMA settings needed. In most instances, when
the converter is connected to a PCs USB port or to a self-powered USB, no additional power supply is
required. However, if required, an optional 5V DC (+ on centre) USB power supply with mini DC jack may
be used to self power the converter.
