6. ble installation is desired one convenient way to do this is to have a removable wire section with Deans or other plugs on either end male female Both the current and voltage leads of the Electric Expander can attach to this wire section the alligator clip is normally cut off and the voltage wire soldered and the section can be removed easily from the model when electric measurement is not desired ESCs with isolation between BEC Throttle ground and Main Battery Ground Note that there must be electrical conductivity between the ground wire of your main battery and the Recorder s internal ground for voltage measurement to work correctly Normally when the Recorder is connected to your receiver via one or more of the Recorder s servo connections the ground wire of the ESC s BEC Throttle output results in the correct grounding However some ESCs isolate battery ground from the ESC BEC throttle output ground The easiest way to tell if there is ground isolation is with everything disconnected from your ESC to measure the resistance between y the main battery negative input of the o Small 4 8V to 6V ESC and the BEC Throttle ground Battery wire If the resistance is greater than an ohm or two there is isolation To negative lead of Main j Small Wire Battery In these cases for the Recorder to measure voltage correctly the recorder s ground must be connected to the ground of the battery to be measur

8. ed Figure 2 There are two ways to do this a RECOMMENDED Disconnect all connections between your Receiver including BEC Throttle output of the ESC and your Recorder and power the recorder from a separate small battery Then connect a small ground wire between one of the Recorder s servo ground pins and the negative lead of the battery being measured as shown in Figure 2 Note that the resulting connections should not bypass the ESC s isolation between the BEC Throttle ground and the ground of the battery being measured since the BEC Throttle ground is NOT connected to the recorder Note that servo position logging will not be possible in this scenario b If you want to continue to power the Recorder from the ESC s BEC output or the battery you are using to power the Receiver and to be able to log servo positions you will need to leave the servo connections from the Receiver to the Copyright 2003 2010 Eagle Tree Systems LLC http www eagletreesystems com Page 3 Recorder connected AND you will need to connect the small wire between the between one of the Recorder s servo ground pins and the negative lead of the battery being measured as shown in Figure 2 CAUTION This configuration causes the internal ESC isolation to be bypassed While the vast majority of the customers who have done this with our equipment have not reported any problems we have had one report of two different high powered ESC s which may have bee
