2.4.6 Interface for Marking-On-The-Fly-Option
With the option Marking-On-The-Fly objects can be marked in motion, for example when mov-
ing along a conveyor. The movement is measured via up to three position encoders. Based on
these moving informations, the SP-ICE 2 control card is able to adapt the marking process to
the actual motion.
The MOTF signals are transferred to a 9 pin Sub-D male connector on a slot bracket via ribbon
cable. This enables the connection of the position encoders at the rear panel of a PC.
Diff. IN = differential TTL signal, O = output
The MOTF interface of the SP-ICE 2 control card is equipped with differential inputs. It pro-
vides the option to use the input signals differential as well as single-ended. The internal circuit
keeps the inputs –A, –B and –C at +2.5Volts, if they are unused.
