[comp.sys.ibm.pc.hardware] Help needed in building an ethernet transceiver!!

kklw@mullian.ee.mu.OZ.AU (Kevin K L WONG) (09/27/90)

I am trying to build a standalone ethernet transceiver for some ethernet
experiments. I am using the National DP8392 Tranceiver chip. There is a
connection diagram given in the data book and I built one exactly as it
says except that I didn't use a DC-DC converter and a separate 9V supply
is used. However, it doesn't work. I am pretty sure that the wirings are
correct. I check with a CRO and found that it can receive since output
is observed at the receive pair. I couldn't figure out how to test the
transmitting though.

Anyone built that circuit before? Is the circuit given in the data book
correct?  Any tips will be great.

If you were using an AMD Transceiver we could help you. Next
time perhaps you'll make the right choice.
