== Communication ==
Communication configuration can be done using the regular communication tab.
Depending on the connection that is used, select the correct {{ScreenElement|Communication Stream}}, and configure the parameters correspondingly.

== Channels ==
AD convertors can have multiple channels on which AD values could be read. The [[Configurable AD Convertor]] device driver is able to retrieve up to 40 measurement values from the measurement device.
For each AD channel, individual commands can be set, specific for the values that should be retrieved.

The configurable AD convertor only needs the numeric value of the measurement device response. The text that is specified in the {{ScreenElement|Read Back}} box, is used as a [[regular expressions]] to determine the returned value.
A good regular expression for finding the first number in scientific notation in a text is:
'''([+-]?[0-9]*\.?[0-9]+([eE][+-]?[0-9]+)?)'''
For more possibilities see the example section.

{{ScreenElementDescription|Movement ready response|This should be the status when the turntable is not moving/rotating}}
{{ScreenElementDescription|Stop|This is the command to abort/stop any rotation}}
{{ScreenElementDescriptionEnd}}
{{ScreenElementDescriptionEnd}}


With minimum set to 0 and maximum set to 1, the raw value won't be converted, but instead directly used as it is included in the response.

The Configurable Turn Table device driver is a Turn Table which is supported by RadiMation®.   It can be used to control other measurement equipment, for which no RadiMation device driver is available yet. The Configurable Turn Table allows to manual create a device driver to controll a Turn Table. Where the device then can be used in RadiMation. The Turn Table can thus be used for tests.

Initialisation and Check[edit]

Configurable Turn Table Configuration Window.png


ScreenElementDescription.svg Reset The reset code that needs to be send to device. When left blank, no command will be send.
ScreenElementDescription.svg Init The command that is send to initialize the configured device. When left blank no command will be send.
ScreenElementDescription.svg Get Id The command that is send to retrieve the ID of the device. This is used to check if the device is connected. A commonly used SCPI command is: *IDN?. When left blank, no command will be send.
ScreenElementDescription.svg Returned ID The identifier is used to check if the correct device driver is selected and the device is connected. Leaving this blank, will skip the device check.
ScreenElementDescription.svg Deinit Specifies the command that is send when the device is no longer controlled. This can for example be used to put the measurement device is an intrinsic safe state. Leaving this blank, will keep the device in its last state after controlling it.
ScreenElementDescription.svg Wait for Completion after sending command The checkmark can be enabled so RadiMation® will wait for all the commands to complete, before it continues. This is done by sending SCPI command *OPC? to the device.


ScreenElementDescription.svg Goto angle The command that should be send to turn the turn table. The command must use the variable name __degree__ or __radian__.
ScreenElementDescription.svg Current Angle This is the command to request the current angle of the device.
ScreenElementDescription.svg Goto angle format This is a regular expression to obtain the current angle to from the reponse of the Current angle command. See regular expression examples below.
ScreenElementDescription.svg Movement ready This is the command to request the current status of the turn table.
ScreenElementDescription.svg Movement ready response This should be the status when the turntable is not moving/rotating
ScreenElementDescription.svg Stop This is the command to abort/stop any rotation
