3.2. OBSIDIAN® device connection options
OBSIDIAN® is a multifunctional device that can be utilized either as a standalone data logging device or
as a EtherCAT device (as an IOLITE device). These two modes exhibit significant differences in terms of
hardware connection, software configuration, supported software options, and more. The two possible
configuration modes are:
OBSIDIAN® V23-1 6/54

OBSIDIAN®
TECHNICAL REFERENCE MANUAL
-Standalone mode - when used as a standalone device, the software on the embedded Linux
system is controlling the OBSIDIAN device therefore an additional PC for data acquisition/storing
is not required. The PC with DewesoftX software is only needed for the device configuration. To
start the configuration, the device needs to be connected to the PC over a GLAN connector.
When connected over GLAN, also the three RT modules are enabled, for signal conditioning:
- CAN RT out
- XCP out
- AO RT out
-External master mode (EtherCAT) mode - when used as a standard EtherCAT device, the
OBSIDIAN® needs to be connected over an 8-pin Lemo EtherCAT connector to the PC. In this
mode the OBSIDIAN® device behaves the same way as the IOLITE device. For additional
information please refer to the IOLITE manual.
Important
This manual will mostly focus on the Standalone mode. Only configuration and features related
to the standalone mode will be described. For more information regarding the behavior,
functionality and features of external master (EtherCAT) mode please refer to the IOLITE
manual.
3.3. Connecting OBSIDIAN® device in standalone mode
First connect the power supply cable (PS-120-L1B2f) to the PWR IN 2-pin LEMO 1B male connector. Then
connect the Ethernet Cable with the RJ-45 connector to the appropriate GLAN connector on the back of
the OBSIDIAN® device. Finally, connect the other side of the ethernet cable to the LAN port of the PC.

3.3.2.2. Synchronization of the connected system
When the device is already added in DewesoftX software you need to go to “Local system” settings and
under “Synchronization” you can adjust the synchronization configuration for the connected system.
When running as a standalone device, no additional synchronization is needed and the settings can be
left on “Automatic”. In combination with other DewesoftX devices you can use IRIG synchronization.
OBSIDIAN currently supports only IRIG-IN option, meaning that device can not generate IRIG signal.
Hint
When the device is in external master mode (EtherCAT mode) also IRIG-OUT synchronization is
supported.
3.3.2.3. Device properties
By clicking on OBSIDIAN-R8 inside the device list, you will see the device information such as device
serial number, IP address, HW version, FW version, operation/rt-mode and other information. Under
Network settings you can again reach the device network settings and change the IP address of the
currently connected device.
Under the EtherCAT settings we have two options:
-Use external master mode - the options configure the device to work in standard EtherCAT
mode. Please go to Chapter 3.5. Connecting OBSIDIAN® device in standard EtherCAT mode for
more information
-Legacy: Enable control over EtherCAT scan cycle frequency - this option offers quicker
response times [1ms loop time for AO RT module] when signal conditioning is used. This mode is
not recommended for logging applications.

TECHNICAL REFERENCE MANUAL
All the channels that are selected to “Used” in the Analog-in module, can be later used in any of the
RT-modules.
3.4.3. Sample rate
As mentioned before, the maximum sample rate on the OBSIDIAN® device is 20kHz, but it differs per
the IOLITE DAQ module. The OBSIDIAN device only supports different sample rates per IOLITE DAQ
module. This means that all the channels from the same IOLITE DAQ module need to have the same
sample rate. The different sample rates can be selected per different IOLITE DAQ modules within
supported sample rate dividers.
For example, all amplifiers from the IOLITE-TH module can run on 100Hz while all the amplifiers from
IOLITE-STG can run on 10kHz and IOLITE-LV amplifiers run with a maximum 20kHz rate in the same
configuration.
Example of sample rates per channel
Important
OBSIDIAN® device doesn’t support binary sample rates (such as 512, 1024), due to EtherCAT
limitation.
