The Latest Firmware for your spectrum - R008 – eMotimo

What firmware should I use?

RC008_018 is what is shipping with all new eMotimo spectrum ST4 and ST4.3's

To update the firmware

Round up the MicroSD card that came with your ST4. It is a small 8 or 16GB card formatted FAT32. Every unit ships with this card to avoid compatibility issue when updating firmware.
Download the .srec firmware file you want from this page.
copy .srec file under (or into) the update folder of your uSD card so it looks like SDCARD:/update/ST4_RC000_xx.srec. If the card is blank you need to create the update folder. HEY YOU! Location matters. Do not put the srec file into the "update/firmwares" folder . . .don't put in in the root . . . really -only put it in the update folder!
Insert the uSD card to the spectrum - make sure it goes in straight and is fully seated.
Power on and wait 30-45 seconds, the screen will be blank while updating - check that the new firmware flashes on the screen on startup.
Remove and store the card for safekeeping

Power Considerations: It is recommended to use 24V power source when using Dragonframe with Tilta integration. It is also important to note that the 24V power source should be connected to the ST4 before plugging the USB port into your computer. Never Plug the USB Cable in before the Spectrum has Powered On from either AC or Battery Sources.

RC007_58SP2 (4/15/2021) - Currently being shipped with all new spectrum ST4's

BugFix for our standard released firmware. All Dragonframe users should update to this version. For all other users, this update is not necessary. The resolved issue had to do with the ST4 incorrectly reporting the M3 (typically slider) motor as stationary during a move. This causes issues with Dragonframe then initiating a camera capture for a potentially moving motor.
Additionally, for any user intermittently experiencing an issue where your screen is not displaying correctly on startup, this resolves the issue.

RC007_110 (5/7/2021)

Adds New Option in Settings Menu to select what virtual Stop you want to set with the L1/R1 buttons on the remote. Go to Settings, 5th Screen, L1/R1 Stops: and select what you want to happen when you click the L1/R1 buttons. The four options are:
- M4 only (default) where the L1/R1 acts like most other firmware and sets virtual stops for the Focus port (M4)
- M3 Only - for slide control only or whatever you have connected to the M3 port.
- M3+M4 - Both stops are set at the same time. This gets trickier of course as you need to know which side of the stop you are setting. If you haven't set up any motor reversing
  - L1 Sets the furthest joystick left you can go with the M3 port, and the furthest you can go when squeezing the L2 trigger.
  - R1 Sets the furthest joystick right you can go with the M3 port, and the furthest you can go when squeezing the R2 trigger.
- All - Pan, Tilt, M3, M4. All Min stops for Pan/Tilt/M3/M4 are set at the same time by hitting L1. All max stops for all axis are set at the same time by hitting R1
IMPORTANT NOTE - As Always all virtual stops are cleared by hitting the Options button on the PS4 remote.

Updated the way M4 reads feel (this is typically for Fz) We updated the reads from the R2/L2 Squeezy triggers to remove deadzones and make the first 50% of the engagement more sensitive. Several users said getting the lens into the right position was tough with the old "curves". We like the feel better now too.
