CatTouch - FAQs

CatTouch is a new product under continual development. It is safe to use with all supported transceiver models.
For the best experience, you should have the technical ability to upload & install new versions of firmware:

Many modern Yaesu transceivers have more than 1 CAT port allowing CatTouch to use RS232C CAT port & your favorite PC application to use USB CAT & USB audio
All work independently & at the same time

On all models except FT-710, CatTouch plugs into the RS232C CAT port - default speed is 19200bps
There is no RS232C pass through port on CatTouch so if it is used by another device, you cannot use CatTouch or you could use a serial printer switch box to manually switch devices

FT-991 & FT-991a
Set menu 028 GPS/232C → RS232C
Set menu 029 232C RATE → 19200bps

[OPERATION SETTING] → [GENERAL] → [232C RATE] → [19200bps]

FTdx101D, FTdx101MP
[OPERATION SETTING] → [GENERAL] → [232C RATE] → [19200bps]

Set menu 039 CAT RATE → 19200bps

Set menu 037 CAT SELECT → RS232C
Set menu 038 CAT RATE → 19200

Set menu 032 CAT BPS → 19200

This is a special version of CatTouch that plugs into the TUNER/LINEAR jack
There is no pass through port so if TUNER/LINEAR is in use, you cannot use CatTouch

During development of CatTouch, several Yaesu CAT idiosyncrasies have been observed:
FTdx10, FTdx101D: Clock does not update if transceiver screen saver is on - no fix
FTdx101D/FTdx101MP: Many CAT devices caused transceiver to reboot - update transceiver firmware fixed problem
FT-991A: Clock does not change if clock settings screen open on transceiver - no fix
FT-991A: In C4FM mode, CAT command responses for width, contour & notch are all incorrect - no fix
FT-991A: LCUT slope keeps changing in SSB mode - no fix
FTdx5000 & possibly FTdx3000: MEQ & PROC lights keep flashing on transceiver - no fix

If you find the stylus does not work properly or erratically, reload the firmware
Common symptoms include screen buttons / tabs not working (not the JPG TAB though, it is always slow to react)
This will reset everything & force the calibrate screen to be displayed

When calibrating touch screen, it is important you touch as close as practical to the arrow point
A check is made to make sure a valid point is touched during calibration
Please use the included stylus

When doing a Yaesu Transceiver firmware update, you should disconnect CatTouch & any other device/s from your transceiver

There is no reset button or procedure on CatTouch. Updating firmware restores all factory defaults & you can do this as many times as you like

A firmware update overrides everything & you will need to reapply any settings like Zulu/UTC, 232C rate, voltage offset, Etc

You do not have to upload every sequential firmware version - you can skip firmware versions at any time

To update the firmware, download the latest version from the CatTouch product page
Click here & watch video

During firmware update, do not remove the SD card! You must finish updating & let CatTouch restart before removing SD card

If CatTouch firmware update via SD card did not work or you have a white screen, it can be recovered using this procedure

CatTouch enclosure is 3D printed using biodegradable PLA which is not suitable for direct sunlight or in hot cars
The case STL file is at the bottom of the CatTouch product page. You can use this to print an ABS or PTEG case
