2 1-V and 2.4-V p2p Mode Scripts

The default operating modes depend on the strapping the LED_2 pin. From the quick setup in the previous session, the default output operating mode will be 1.0 Vpp with and without a link partner detected.

Select the output operating mode of the DP83TD510E by running the script below for 2.4 Vpp for both link partners.

//Set Output operating mode for 2.4 Vpp 
begin
08F6 1000 //enable 2.4Vpp operating mode
020E B000 //Request increased the transmit level
001F 4000 //Software restart
end

Select the output operating mode of the DP83TD510E by running the script below for 1 Vpp for both link partners.

//Set Output operating mode for 1 Vpp 
begin
08F6 0000 //enable 1Vpp operating mode
020E 8000 //Do not request increased transmit level
001F 4000 //Software restart
end
