4.5.2 Formats and outputs of the MAGIC measuring system (analogue)
Electrical signals after the differential input of the downstream electronic components. The sinus/cosinus interface of HIWIN
MAGIC is strictly based on the Siemens specifications. The period length of the sinus output signal is 1 mm. The period
length of the reference signal is 1 mm.

electronic components (analogue version)
4.5.3 Formats and outputs of the MAGIC measuring system (digital)
Digital TTL output: 90° phase shifted square signal in compliance with RS422 specification (according to DIN 66259). Dif-
ferential output signal: A, Ā, B, B¯ and Z, Z¯.
