When SYNF is activated, it is possible to force a synchrone dynamic reading between the pairs of
probes 1 / 3 and 2 / 4. The pairs of probes 1 / 2 and 3 /4 can't be synchronized.
8. Analogue outputs (D30Xa modules only)
The D30Xa modules are fitted with an independent analogue output for each of the channels.
The output voltage range may be adjusted to between -10V and +10V for any probe in the Sylvac
range (from 2 - 50mm) with a resolution of 0.025mV.
8.1 Analogue output configuration (D30Xa)
Using the AREF remote command define the reference voltage corresponding to the position
of the probe Preset. Using the AVMM remote command (or AVIN for measurements in inches),
define the voltage range required for moving the probe.
Example: Measurement with a P10 probe (10mm run) between -5V and + 5V. The reference is
-5V. The total measurement range is 10V, therefore the factor is 1V/mm. The 2 remote commands
will therefore be: AREF -5.0 <CR> (reference to -5V for the Preset position) AVMM +1.0 <CR>
(1V/mm of probe run)

9. Remote commands
Each remote command must be followed by a "CR" (Carriage Return).
A remote command is made up of a command and, if necessary, one or more parameters.
By default the remote commands act on all the active module channels to which a probe is
connected. To act on one channel in particular a selection code (F) may be inserted between the
command and the parameter. Example: ? F2 (to interrogate the value of channel 2).
Exception: The ACHA remote command always acts on all channels if code F is not specified.
The module's responses to remote controls acting on several channels are separated by a TAB
character between each channel. Options enable the presentation of the module's responses to
be set up (see OPT remote controls).
The remote commands for pairing (point by point correction) can only act on one single channel at
a time. If the module's two channels are active and the probes are connected, code F is manda-
tory otherwise the command is not executed.
Example: COR F1 RST.
See the attached table of remote commands.
10. Data bus
The D30Xy module is intended to be connected to a data transmission bus. The RS485 IN bus
input connector is used to connect the module to a master (D300S unit or a programmable con-
troller) or to the previous module. The RS485 OUT bus output connector provides the opportunity
to connect to the following module. These two connectors also transport the power as well as an
external command signal (foot switch). A set of jumpers is used to cut off the power supply and/
or the external command signal as well as to configure the end of line module (last module on the
