Mounting Considerations
For the best throughput, the antennas on the TDAS WET should always have direct
line-of-sight with the WAP it will communicate with. Mounting methods and mounting
bolt selection should be carefully calculated so as to withstand expected shock loading.
(See Appendix B for the unit’s mechanical specifications.)
Temperature Rating
It is extremely unlikely that excessive heating (temperatures in excess of 50°C) will
ever be an issue in real-world testing applications using the TDAS WET. Should you
have any questions about its use in your environment, please contact DTS.
Using Your TDAS WET with other TDAS Equipment
Your TDAS WET can be used with TDAS PRO racks, TDAS G5 Vehicle Docking Stations,
TDAS PLUS Distributors, TDAS PLUS Mini Distributors and TDAS PLUS Crashworthy
Batteries. If you are interconnecting equipment to create higher channel-count
systems, please refer to the specific product manual for that information.
TDAS PRO racks and TDAS G5 Vehicle Docking Stations
Communications to and from the TDAS WET to racks or vehicle docking stations
require an RDC cable. The TDAS WET can be at either end of the chain or in the
middle.
Using an RDC cable, connect the end marked “MASTER” to either COM port of
the rack or vehicle docking station. Connect the end marked “SLAVE” to either
COM port on the TDAS WET.
If the TDAS WET is in the middle of the chain, use a second RDC cable and
connect the end marked “MASTER” to the open COM port on the TDAS WET.
Connect the end marked “SLAVE” to either COM port on the third device in the
chain. (This process is the same for all interconnections between TDAS
equipment having two COM ports; all equipment in the middle of the chain have
both a “MASTER” and “SLAVE” cable end connected.)
You will need to power the TDAS WET from an external 12 V power source.
TDAS PLUS Distributor
Communications to and from the TDAS WET and a TDAS PLUS Distributor require an
RDC cable. Note: Not all TDAS PLUS Distributor configurations include communication
features.
Using an RDC cable, connect the end marked “MASTER” to an AUXILIARY PORT
on the TDAS PLUS Distributor. Connect the cable end marked “SLAVE” to either
COM port on the TDAS WET.
If the TDAS WET is in the middle of the chain, use a second RDC cable and
connect the end marked “MASTER” to the open COM port on the TDAS WET.
Connect the end marked “SLAVE” to either COM port on the third device in the
chain. (This process is the same for all interconnections between TDAS
