I’m having the WIZ107SR-RS232 here, but I would like to use it as TTL instead of the RS-232.
Referring to the schematic wiz107sr_rev1_4.pdf for WIZ107SR, is the following step correct to make it as TTL version:
In theWIZ107SR User Manual, 2.1.1 Network Configuration, it mentions that the configuration can be saved in the EEPROM. However, seem like the EEPROM is not been populated on the module itself, so does it means this function won’t work?
Setting
This function is to complete the configuration change.
If you select the MAC Address from the “Serial to Ethernet” tree, the default
configuration value of the module will be displayed. Change the configuration and click
“Setting” button to complete the configuration. The module will re-initialize with the
changed configuration. Changed value is saved in the EEPROM of the module. Thus, the
value is not removed even though power is disconnected.
The firmware file of the W7100A chip pre-programmed same as WIZ107SR firmware.
So I refer to WIZ107SR firmware file.WIZ107SRv4_06p.zip (22.6 KB)
W7100A firmware upload uses WizISP tool.
First, it set to high with BOOTEN pin(VCC). And active reset (low) and then access WizISP tool.
WizISP tool user’s guide is inside zip files. refer to inside guide.
Do you have the source code for the WIZ107SRv4_06p.zip?
What is the default configuration (baudrate, parity, stop bit etc) of UART for the pre-programmed W7100A chip?
In my design, i’m using two sets of W7100A to work as the serial to ethernet converter, base on the WIZ107SR reference design. I’m able to establish the connection to each of this individual sets of W7100A to PC through the RJ-45 port. However, when i perform a back-to-back connection from one RJ-45 port on my design to the other RJ-45 port on my design, the Green LED light on the RJ-45 doesn’t light up. It seems the back-to-back connection is not linked. What could be the possible problem in this case?
please tell me connection diagram.
each W7100A can search on configuration tool?
If you possible search on configuration tool, I think it has connected problem.
So tell me connection diagram.
You have to different set each W7100A.
For example, left W7100A set TCP server and right W7100A set TCP client.
You don’t directly connection. You must connect with HUB.
(W7100A) — (LAN cable) — (HUB) — (LANCable) — (W7100A)
However If it doesn’t working, you should test each W7100A. such as loopback test.
If each W7100A loopback test is work well, I think it is wrong hub or not good connection.
When i connect the (W7100A) - (LAN cable) - (W7100A) directly, the LINK LED doesn’t light-up/blink.
I have tried with both the direct and cross LAN cable, and it doesn’t work for both cases.
In our application, we will need it to be able to connect directly without going through the hub.
Yes, the circuit is based on the reference circuit of WIZ107SR (rev1.4).
