INTRODUCTION
Thank you for purchasing the Manhattan®USB to RS485 Converter, Model
150439.
This handy converter transforms any standard full-duplex USB port into a two-
wire, half-duplex communication channel with a range of up to 1200 m (3900 ft.).
Automatically detected and installed as a native Com port without IRQ or DMA
conguration, it provides USB connectivity with plug-and-play and hot-swap
capabilities to legacy devices and connects them to newer PCs with fewer device
conicts. Its Windows XP/Vista/7/8 compatibility, bus power and rugged
construction help provide reliable performance without an external power supply
or complicated setup.
By following the instructions in this user manual — or the simpler setup procedure
in the printed quick install guide included with the product — you’ll soon be enjoying
these popular features:
• Overcurrent protection: 600 W between USB port and RS485
• 384-byte receive buffer
