[Elphel-support] Extension of stereobase and elongation sensor's cable length

Forgot to send a copy back to the mailing-list:

I don't know.
With SENSOR_PHASE unchanged try several points within each quarter
for MULTI_PHASE1, e.g.:
0x8ff70, 0x80000, 0x80070,
0x9ff70, ...
0xaff70, ...
0xbff70, 0xb0000, 0xb0070.

Sometimes a phase shifter (digital clock manager in the fpga) can get stuck
- so it's safer to set 15th bit to 1 to reset it.
You can try with a 450mm cable if the long one can be easily disassembled.

2.
How exactly do you connect 2 cables? picture?
Any difference in the voltage levels on the ends between 450mm and 900mm
setups?

3.
If both images are broken in the same manner then try to change
the SENSOR_PHASE.
