The default switch values set in the Edit Info window will be used when creating the switches.
Test Mode
- Revert to showing permanent connection's name if item goes bad during continuous permanent connection test. Was turning red but potentially showing previous good value.
- Make sure LED icon in item indicates the correct LED color at end of illumination testing.
- Prevent errors at end of test due to a Keypad File being read only.

V3.4.0

Please note that a keypad file created, edited or used for testing by this version of Mistral software can not be read by previous versions. If you store your keypad files on a central server you may want to restrict write access until all workstations have been updated to the latest version.

General
- Add ability to print the time on labels.
- Add ability to set the text that is printed on a label when a keypad passes or fails.
- Make buttons that control testing, learning, etc. larger if window size is greater than approximately 700 pixels.
Test Mode
- Add ability to do a continuous electrical test on permanent connections. This option can be enabled in the "Testing" tab of the Edit Info window.
- If "Illuminate each LED for confirmation by operator" is enabled in the "Testing" tab of the Edit Info window and it is set to cycle at the "Max" rate, LEDs will be cycled at a high enough rate to make them appear to all be on. Note that the more LEDs there are on a keypad, the dimmer they will appear. This feature requires pod firmware V4.2 or later, which is included with the software.
- Fix bug that caused resistances over 10M Ohms to be expressed in scientific notation in Job Logs.
- Fix bug that could prevent Summary Job Logs from being saved if the names for any of the items are less than four characters long.

V3.3.0

Please note that a keypad file created, edited or used for testing by this version of Mistral software can not be read by previous versions. If you store your keypad files on a central server you may want to restrict write access until all workstations have been updated to the latest version.

General
- Add additional light sensor item configuration with three pins and a voltage output. To select new sensor type, select an existing sensor item or create a new one, click on the sensor button in the upper right corner of the properties window and choose "Three Terminal Voltage Output Sensor". This sensor is only supported with modified Mistral pods.

V3.2.0

Please note that a keypad file created, edited or used for testing by this version of Mistral software can not be read by previous versions. If you store your keypad files on a central server you may want to restrict write access until all workstations have been updated to the latest version.

General
- Add switched diode, switched LED, light sensor and 7-segment LED display items. Switched diode and switched LED items allow testing of switches in series with diodes where the connection between the switch and diode is not available on a connector. Light sensors can be two pin photodiodes or phototransistors. Three pin sensors are only supported with modified Mistral pods.
- Add ability to group any combination of switch, switched diode and switched LED for keypad switches that connect more than two pins.
- Improve loading of fonts to reduce program startup time.
- Add support for pods with software V4.
- Add information about pod to About window.
Test Mode
- Add green and red banners to the pass and fail messages respectively to make failures more obvious to the operator.
- Improve logging of resistances, voltages and currents by including more significant digits. This allows the log to more accurately record the values used to make pass/fail decisions.
- Add ability to test switches in parallel with LEDs.
Edit Mode
- Preserve switch groups when setting the Test Sequence.
Learn Mode
- Add ability to learn switched diodes and switch groups. This change did increase the response time for switch presses while learning, particularly for 62 point systems. As always, hold the switch down until the pod beeps.
Pod Firmware
- New V4.1 pod firmware improves reliability and could prevent damage to pod from static discharge or power failures while testing. You will be prompted to install the upgrade when you run the program with a pod running older firmware.

- Add the ability to quit the job if a file has a fail password, the part has failed and the password is not known.
- Fix bug that caused communication errors to be displayed if a new short was detected while scanning for switches.
- Improve reporting of any Keypad File problems that prevent it from being used for testing.
Edit Mode
- Reduce minimum font size from 6 to 4 for label fields.
General
- Add support for updated Mistrals with black cases.

Test Mode
- Fix bug that caused extra switches to be detected when one side of a switch was connected to a permanent connection.
Edit Mode
- Reduce default current used to measure LED forward voltage from 10mA to 1mA for new Keypad Files. This should reduce forward voltage errors due to LED circuit path resistance. Note that default current can still be changed in the Edit Info for the Keypad File and individual currents can be set when the LED item is selected.
Learn Mode
- Significantly improve the speed with which the Mistral recognizes key presses.
