FAQ

IISI Cockpit

Q: Since V2.11, my Cockpit shows that a file is not found, e.g. “70s.isi”. What’s wrong?

A: This is a bug in V2.11 of 4/11/2015. Please download and copy the file image.bin (here) once again on your Cockpit, this will fix the problem.


Q: I’ve seen that the V1.12 Cockpit version does not support the TXE V1.0 anymore. Does this mean I cannot use them anymore?

A: You’ve most probably a TXE V1.1. You can find out the TXE version by connecting it to the Cockpit V1.11. The version is shown up for a second, showing e.g. “TXE V1.1”. If you have TXE V1.0, please contact us. The Cockpit V1.11 will remain at your disposal.


Q: How do I switch the IISI Cockpit off?

A: Simply hold the joystick to the right, until it switches off.


Q: Where can I charge the IISI Cockpit?

A: Use the included USB cable and connect it to a USB port on your computer, on a powered USB hub, or on any USB charger.


Q: The IISI Cockpit shows ‘Charging...’ but the percentage does not progress. What’s wrong?

A: You may have connected the IISI Cockpit to an unpowered USB hub, or a USB port which is not able to deliver enough current. Try another USB port, which is on your computer.


Q: The ‘Fly Again!’ feature does not work. It is not recognizing a partially discharged battery.

A1: You may have switched off the IISI Cockpit between the flights. Let it run throughout your stay at the field. You may activate the sleep mode to save power.

A2: You may have taken very little energy out of the battery, so the IISI Cockpit can’t recognize a partially discharged battery. Select manually (using UP/DOWN while registering) ‘Go again’.


Q: Why does a model have to be registered on the IISI Cockpit?

A: Every flight is handled individually by the IISI Cockpit. A registering clears also data from former flights, and is needed for the ‘Fly Again!’ feature.


Q: What is the ‘Fly Again!’ feature?

A: If you have a model which may do more than one flight with the same battery, but you want to do more flights with other models in between, or take a break. The IISI Cockpit recognizes that you’ve already registered your model before and that the battery is partially discharged. The IISI Cockpit calculates for you the remaining battery capacity and proposes ‘Go Again’ for registering. You can repeat this as many times as you want, but the number of different models per session is limited to 16. Don’t switch off your IISI Cockpit during the day, otherwise the actual data will be lost.



TXE30 / TXE100

Q: The TXE is powered up, the LED blinks, but my IISI Cockpit does not recognize it.

A: The TXEs must be paired with your IISI Cockpit once, prior to use. Connect the TXE to the Cockpit using the programming cable. It will show ‘pairing needed’, follow the procedure. Please note that with Cockpit Version V1.12, only TXEs with version > V1.1 are supported. See FAQ Cockpit.


Q: My motor draws 35A, is this a problem for the TXE30?

A: No. The current sensor supports 60A peak current. But the energy measurement will not be correct, so you may not be alerted correctly. If this happens very rarely, and only for very short moments, you may accept this.


Q: My motor draws 105A, is this a problem for the TXE100?

A: No. The current sensor supports >300A peak current. But the energy measurement will not be correct, so you may not be alerted correctly. If this happens very rarely, and only for very short moments, you may accept this.


Q: Why should I set parameters in the TXE30?

A: The model name is used to separate different models from each other, especially for the ‘Fly Again!’ feature.

The battery setup is needed to do checks at startup and to activate alarms, etc.


Q: How do I set the default capacity, it’s an older battery, and I don’t know it exactly.

A: Charge your battery and plug it in. Choose the nominal capacity as a starting value. Now you empty your battery by having your motor running on the ground (fix your plane). Do not use constant full throttle, but simulate a normal flight. (You obviously can also do a normal flight, as you probably did before.) When your battery becomes empty (ESC shuts down, or voltage level has reached a critical value, e.g. 3.0V for LiPo), you can see the battery capacity on your IISI Cockpit (e.g. 1.95Ah). Program this value into the TXE.


Q: I have a TS60 temperature sensor connected to the IISI-Link, but I can’t see the temperature values.

A: You may have selected ‘EXP only’ during configuration of the TXE. Connect the IISI Cockpit to the TXE using the programming cable and go to this menu, then select the temperature sensor option, including temp sensor name and alarm value.


Q: Everything works o.k. but current is always 0.0A, even when the motor runs.

A: You have inverted the +BAT and the +ESC cables on the TXE. The current is flowing in the reverse direction. Check your installation.


Q: Will I get less performance when using the TXE?

A: No. The TXE use both hall current sensors, there is no shunt resistance. The TXE is seen just as a piece of wire and has probably much less resistance than your battery connector.


Q: Can I use the TXE30 to observe my receiver battery in my gas plane?

A: Yes, you can, but the voltage must be higher than 6Volts. This works if you use e.g. a 2S LiPo. Be sure to disconnect the TXE30 after usage, it will discharge your battery completely! Don’t expect the result to be very accurate, as the system is designed for high current (=motor) applications. But you can rely on the battery voltage. Please contact us if you need more information about this application.


Q: The LED is not blinking when the TXE is connected to the battery. What’s wrong?

A: The TXE is probably damaged, due to reverse connection or other reasons. Please contact us.


Q: Why does the TXE default capacity change when a LIPO6 is used?

A: The LIPO6 has its individual setting for the default capacity, which has priority against the setting in the TXE. If you don’t want to use this feature, set the capacity in the LIPO6 to 0.00Ah.
