9.9. measuring system connection: SENSOR
Only for actuators with measuring system: Please plug in the measuring system here.
9.10. RS232 interface
In the case of controlling the amplifier over the interface, the potentiometer DC-LEVEL
is deactivated. Depending on the operation mode the display announces the output
voltage for the position.
Communication with the NV40/1CLE occurs via the RS232 interface (ASCII character
concatenation). The character string must be concluded with ENTER. ASCII characters
less then 20h (hexadecimal) except for ENTER (13h), will be ignored.
A valid command looks like:
command, parameter <CR>
If the internal processor recognizes the command it is carried out. If the sent command
is not in the intern command list or was sent erroneously, an error report would be
created. The report describes the occurred error.
Interface set up: 9600 Baud, 1 Start / Stop-Bit, no parity

9.10.1. write-command wr
wr,10.29<CR> open loop:10.29V; closed loop:10.29µm
The command wr commands a voltage to the actuator in the open loop operating mode.
In the closed loop operation the motion is shown in µm. Additionally the remote control
has to be activated.
