10.1.1 List of commands Service Standard
protocol
The basic principle of the application is that the
PC (or a terminal) sends an ASCII command (cha-
racter), possibly with additional numeric parame-
ters. In turn, the AEA111/1 sends an appropriate
response (see following table):
Parameter:
19200 baud, no parity, 8 bit, 1
Stop bit, no hand shake
Output:
ASCII (if not otherwise specified)
Value ranges: 2/3 Byte: 0...65535 / 0... +-2
23
Input:
Capitals and small letters are ac-
cepted.
Output:
All response telegrams are com-
pleted with a CR (=hex13), except
for the "W" command.

10.2 SIKONETZ3 Protocol description
The SIKONETZ3 protocol enables parameterization
and output of position values by the AEA111/1. The
data signals comply with the RS485 standard. Up
to 31 devices may be addressed via bus since an
address is included in each telegram. The address
of each device is factory set to the value "01".
Therfore, first re-program all parameters (counting
direction, calibration value...), particularly the de-
vice address (01...31) via Service standard protocol
(see chapter 10.1) before operating the device on
a bus. following this basic parameterization, seit-
ching over to the SIKONETZ3 protocol and, thus,
bus operation is possible (SW1.2).
The protocol setup follows the Master-Slave-Sys-
tem; the translation module only has the slave
function.
