Rs-232 Communication Device - Matthews Marking Systems I-Mark SX-32e Technical Manual

I•Mark SX-32e Technical Manual Version: 8 Issue: 1
Installing
Only use Matthews approved speed encoders.
A speed encoder is a precision instrument and should be mounted accordingly. Place
the speed encoder so that it is well protected from knocks and vibration.
Ensure that there is no play between the speed encoder shaft and the drive as this will
otherwise affect the printout. It is also important that the speed encoder is mounted so
that it reflects exactly the motion of the print target.

RS-232 Communication Device

See also "Connecting an RS-232 Communication Device" on page 19.
Using I-Mark ASCII Protocol, any device (such as a PC, etc.) can communicate with
the SX-32e control unit via an RS-232 serial interface which complies with the
following specifications:
RS-232 Specification
Driver output signal level
Receiver Input voltage range
Receiver Input sensitivity
Maximum cable length
Communication over distances greater than 15 m can be achieved by converting to
RS-422 or 20mA current loop. Please contact your dealer for details.
