Figure 14 Reference Design for Module Without Transformer
This module Ethernet interface default is for the application with transformer
connection. If you need PHY-PHY directly connection, please refer to the Ethernet
connection with transformer design and take AT+FEPTP command as reference.
The commands required:
AT+VEW=enable<CR>
to open ethernet WAN port function (reset to default
configuration by
Reload)
AT+FVEW=enable<CR>
to open ethernet WAN port function (Reload is unavailable)
Remark:
1. Only when ethernet as WAN, this command is needed. Module default LAN port.
2. After this command, make sure module WAN IP and LAN IP in different segment.
(Modify the LAN IP in AP Settings, modify the WAN IP in STA Settings)
AT+FEPTP=om<CR>
Quey/set default ethernet PHY-PHY on/off
AT+FEPGT=on<CR>
Open ethernet function permanently
AT+RELD<CR>
Command with “F” need to be affective after AT+RELD
After module reset, command effect, and will not impact by Reload.
For user’s design, please note:
1. Cable connection should be AC coupling, your cable need be pulled up to VCC (fit
with PHY chip level)
2. Cable TX connected to RX. In PHY-PHY direct connection, PHY chip does not support
direct/cross self-adaption
3. Your PHY chip on board should better to be forced into 100M work mode
4. You could configure the AT command of module by UART port or WIFI. The detailed
setting please refer to the AT command of reference manual of chip.
