1. INTRODUCTION
IPEX PH485Y12 is a 1 to 2 RS-485/RS-422 HUB that provides #2 RS-485 (Half-Duplex) or RS-422 (Full-
Duplex) ports from one single RS-485/RS-422 port. It works with Baud-Rate from 300bps to
230400bps. Using this device, you can connect a RS-485/RS-422 line, to 2 different devices.
PH485Y12 can also be used as a RS-485/RS-422 Repeater and Amplifier. In addition, due to the fact
that 3kV Optical and Electrical insulations have been used in the design of this device, this means all
the ports are insulated from each other, so using this device in the RS-485/RS-422 line, can be very
effective in eliminating electrically and electromagnetically noises. Also, the length of the RS-
485/RS-422 line increases from 1200m to 2400m (1200m on each side).
Protection against Surge, ESD and EMI is considered in its design, so, PH485Y12 is good for industrial
usage and are useful for Industrial Automation, Telecommunications, SCADA systems, DCS
systems...
