Test results of the proportional drift tube (PDT) electronics for the Muon Upgrade at the D0 experiment at Fermilab are described. Prototypes of two front-end boards and two readout VME modules comprising a deadtimeless readout system have been built and tested. The front-end electronics prototypes include an eight-channel front-end board and a control board. The front-end board is capable of registering PDT anode wire signals with a 1 μA threshold and two cathode pad charges at a resolution of 5 fC. Control board features include a sequencer for collecting data from up to four front-end boards, two digital signal processors (DSP), and two serial link transmitters. A serial link transports data a 100 meters from the control board to the VME based muon readout card. The muon readout card receives timing and control signals from the muon fanout card and re-transmits them to the control board. Initial tests with internal pulsers simulating detector signals and further tests with cosmic rays are described. We have tested three data taking modes. The prototype readout system transfers PDT data without deadtime at 16 mbyte/s with a level 1 trigger rate of 10 kHz
