MSA510/1
32 Commissioning
For programming proceed as follows:
Use a level converter (e. g. type I-7520 from Spectra company) to estab-
lish a connection between your PC's serial RS232 interface and the sen-
sor's RS485 interface.
Switch on the sensor's power supply and start with programming by:
• starting a suitable terminal program and by manually entering your
commands accord. to the table "list of commands – service operation
of MSA510/1" (see chapter 6). Please remember that your terminal
has to be adjusted to the pre-programmed interface parameters.

5.3 Sensor's SSI-interface

MSA510/1's SSI-interface allows a synchronous output of the position
value. Its data format comprises a width of 24 bit which are either issued
as Gray or binary codes (see chapter 6) and right-aligned. All following
bits (25, 26...) are issued as "0".
Data and cycle signals correspond to RS422. Typical SSI monoflop time is
20 ... 25 μs which gives a min. cycle rate of 62.5 kHz.
• Cable length 10 m:
• Cable length 100 m:
• Cable length 200 m:
Please note that the possible max. cycle rate and data integrity mainly
depend on the length of the connection line.
