GENERAL
AEAT-86AD Multiturn Encoder Module is integrated with
a controller. The controller provides data synchronization
between Single Turn Absolute Encoder Module (i.e. AEAS-
7X00) and basic multiturn encoder module. Its combines
the serial data from both modules into combined (n
n
The most significant bit (MSB) will always be sent first to
DATA+.
With integrated RS422 line driver and receiver, the differ-
ential data transmission is compatible with EIA standard
RS-422.
SRCLK+ and SRCLK -
SRCLK input pins are used to clocked out the serial out-
puts data through the DATA pins. Lapse time between
words or subsequent data frame must be 40 µs or longer
for proper data transmission.
DATA+ and DATA -
DATA output pins provides positional information via
synchronous serial interface, which consists of n
of serial data from multiturn module and n
data from single turn module.

MSBINV
The MSB can be inverted (counting direction) by using
MSBINV.
STROBE
STROBE output pin can be used to determine whether
the data is locked or changing. It is high when date is
locked, but low when data is changing.
CONNECTION TO AEAS-7X00
Besides VDDA, VDD and GND of AEAS-7x00 need to be
connected to the Multiturn Encoder Module, data and
control i/o pins also need to be connected and soldered,
i.e. NSDOUT, N2SCL, N2NSL and N2DIN
