I was wondering if anyone has used the 140SR to control a half duplex RS-485 bus? I’d like to have both RS-232 & RS-485 ports.
WIZ140SR is TTL level. So if you want RS232 & RS485, you need create base board.
there is WIZ550web + web base board. It is supports RS232 & RS485.
you want cost down ? if so WIZ550S2E(there is RS232 version & RS485 version), WIZ107SR(RS232) , WIZ108SR(RS485/422).
Thank you Edward.
I realize the WIZ140SR is TTL. What I was wondering was if it supports turning on and off the Driver enable pin that would be required for a half duplex RS-485 bus.
As for the other products, I need four ports total, three RS232 & one RSf85, so that’s why I was looking at the WIZ140SR
Yes, you can use WIZ140SR for RS485.
It has capability to drive RS485 transceiver and is “RTS Only” amongst options of Flow Control.
