INTRODUCTION
IPEX
PH232T485Y11
is a Bi-Directional RS-232/TTL UART to RS-485 and RS-422 Converter that
converts RxD & TxD signals of RS-232 standard to differential (Data+ & Data-) signals of RS-485
standard and (RX+, RX- & TX+, TX-) signals of RS-422 standard at a same time. It works with Baud-
Rate from 300bps to 230400bps
Since RS-485 is a Half-Duplex standard, switching between Transmit and Receive is done
automatically and further signals (such as RTS) are not required.
PH232T485Y11
supports Point-to-
Point and Point-to-Multi Point Party Line network topologies.
There are 3kV Optical and Electrical insulations have between RS-232/TTL UART and RS-485/422
sides, thus using this device in the RS-485/RS-422 line, can be very effective in eliminating electrically
and electromagnetically noises.
Protection against Surge, ESD and EMI is considered in its design, so,
PH232T485Y11
is good for
industrial usage and is useful for Industrial Automation, Telecommunications, SCADA Systems, DCS
Systems and …
