6.11 Synchronizing multiple ClipX CF amplifiers

You should synchronize multiple ClipX devices that supply sensors with carrier
frequency (CF) so that the carrier frequency measuring amplifiers do not inter-
fere with each other. This will prevent crosstalk between adjacent sensor
cables, resulting in disturbance to measurements. If you are using only sensors
with direct voltage (DC) amplifiers, no synchronization is necessary.
To synchronize, interconnect the Sync terminals of the devices and the ClipX
bus GND terminals, unless you have already connected the latter to transmit
measured values. Lay the lines from the first device to the second, from the sec-
ond to the third device, etc. (line topology). The cable must have twisted-pair
wires, and be shielded. The ClipX bus GND and Sync lines must be twisted and
shielded.
