1. INTRODUCTION
IPEX PH232Y12 is a 1 to 2 RS-232 HUB that provides #2 RS-232 (Full Duplex) ports from one single
RS-232 port. It works with Baud-Rate from 300bps to 230400bps. Using this device, you can connect
a RS-232 line, to 2 different devices.
PH232Y12 can also be used as a RS-232 Repeater, Amplifier and Y-Switch. All communications are
Full-Duplex. In addition, 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-232
line, can be very effective in eliminating electrically and electromagnetically noises. Also, the length
of the RS-232 line increases from 15m to 30m (15m on each side).
Protection against Surge, ESD and EMI is considered in its design, so, PH232Y12 is good for industrial
usage and are useful for Industrial Automation, Telecommunications, SCADA systems, DCS
systems...
