CUCommand With the CU Command the most important parameters of the internal or external CU
General: The specified indicators are also available via Modbus or via the Dialog 900 program. Be-
cause the query speed may be lower than the update the display speed of the EC 900, reading the
display on the EC 900 is preferable.
Controlling the CU via the optical interface of the corrector (MU): There is a command parameter
for this purpose. With the command parameters complex functions such as resetting the CU or
deleting one of the CU archives can be started in the CU. Besides the complex functions parameter
contents of the CU can be retrieved, where the retrieved values are represented as text with a max-
imum of 16 characters. To change a parameter of the CU, the address of the parameter must be
entered into the command register and, if required, the additional options into the command pa-
rameters. For all transfers to the CU it is to make sure that the command is entered last. Once the
command is entered, it will be sent to the CU during next data exchange between MU and CU.
Command and command parameters are checked before the transmission. If the values are illegal,
the command is not executed. In any case, the command register and the 4 command parameters
are deleted when the command is passed to the CU or in case of an incorrect command. If the
command is executed, the acknowledgment of the command is visible in the display field CUA.

This screen can only be accessed if the M code is entered!
Here you can check communications between the main unit (MU) and the communication module
(CU).
>R cnt and >S cnt are counters which continue to run with every data exchange. If both counters
are at a standstill, there is no communication on the internal bus.

Here, each digit has its own meaning:
00001 -> PIN successfully transferred
00010 -> logged in the home network
00100 -> roaming
01000 -> query response OK
10000 -> error in the PIN dialog
can be changed via the optical interface of the corrector. With the command param-
eters up to four additional parameters (CUBef.Px) can be passed to the CU in addi-
tion to the command. The corresponding commands and parameters can be found in
the annex.
