DNR-X-1G Series RACKtangle and HalfRACK Systems
Refer to the applicable I/O board manuals and data sheets for pinouts and
proper wiring to boards.
DNR-X-1G systems come from the factory fully configured and calibrated.
Individual modules are designed for field replacement and are not suited for field
repairs.
If you encounter a problem with a DNR system, you can powerdown your
system and remove and replace individual boards or other system modules in
the field. You can also rearrange the locations of boards within the enclosure at
any time; however, note that you may need to reprogram I/O board locations in
your application.
No Hot Swapping
Always turn POWER OFF before performing maintenance on a UEI system.
Failure to observe this warning may result in damage to the equipment and
possible injury to personnel.
If you want to enhance, repair, or otherwise modify a specific I/O board,
however, you must send the module back to the factory or to your local
distributor.
This process requires that you request an RMA number from UEI before
shipping. To do so, contact support@ueidaq.com and provide the following
information:
1. Model Number of the unit, (e.g. DNR-AI-217)
2. Serial Number of the unit
3. Reason for return, (e.g. faulty channel, needs calibration, etc.)
UEI will process the request and issue an RMA number.
The CPU Core Module has two Ethernet ports, NIC1 and NIC2. Either port can
be assigned as the Main Operation Port or as a Diagnostics Port.
The main and diagnostics ports are interchangeable. The user application can
open both ports independently and use separate handles to access each of
them. A port becomes a diagnostics port, which prevents changes in the state of
the ongoing operation, after it is configured and locked-in as a diagnostics port.
This allows great flexibility in IOM wiring — if either port or its cabling fails, you
can use the other port as the main port.
If all I/O boards are in configuration mode and the lock is not set, the diagnostics
port functions as an equivalent of the main port. Any command that can be
executed on the main port can be executed on the diagnostics port as well.
