I have a WIZ752SR-125, which I have changed the local IP and the gateway address to match my network. It then works fine and I can ping it and send data back and forth.
I also have a WIZ752SR-120, but I have not been able to get it to connect to my network after setting it up the same way.
I notice that the pinouts of the WIZ752SR-120 between the datasheet, schematic, and silkscreen are all different and none of them match the WIZ120SR.
I will definitely get a WIZ752SR-EVB and check it out.
Scott, the WIZ752SR-120 board I have in my hand shows the following pin out on the silkscreen:
Pin 1 TX-
Pin 2 TX+
Pin 3 GND
Pin 4 RX+ (Different between schematic and silkscreen)
Pin 5 RX- (Different between schematic and silkscreen)
As far as how I tested:
WIZ752SR-125 Connected PC to UART1 via null modem and used a serial terminal program to change the IP address and the gateway to match my network. I could then ping the board at the fixed IP address I set. I then used a TCP terminal program connected to the same fixed IP address and port for UART1 (5000) to send characters back and forth between the TCP terminal program and the serial terminal program. Everything worked fine.
WIZ752SR-120 Connected UART1 to my micro and sent serial commands to change the IP address and gateway just as I had done on the WIZ752SR-125, and saved the settings (readback correct after power cycle), yet the device does not show up on the network.
Thank you again - I will see what I can learn from the eval board.
Thank you for the description.
So, you tested WIZ752SR-125’ uart & ethernet communication based on PC connection.
Then you connected WIZ752SR-120 to other MCU board via uart, then… connected WIZ752SR-120 to PC via ethernet?
Am I right?
And… what do you mean the device does not show up on the network?
Is the device WIZ752SR-120?
and dose not show up on the network mean no searching on the wiz config tool (if it is, which tool you use?) ?
Also, I need to know which firmware version you use.
