Hello. On 6x2 data pin connector (wiz750sr) for pin 6 (U_DTR0/PHY LINK) and pin 10 (485_SEL). If we are not going to use these pins , do we ground it or leave it floating ?
For (wiz750sr) pin 8 (U_DSR0 / TCP CON / HW_TRIG) , how it function or how we control it ? If jus want to use pin 8 (wiz750sr) just for HW_TRIG same as that of Wiz107sr , how it work ?
Finally. Wanted to replace Wiz107sr to Wiz750sr (TTL) , are all cmd the same ? Like for read address “LI\r\n” , hex “4c490D0A” . Do u have Wiz750sr-TTL user manual/datasheet in pdf ?
