Choose a proper site*
: The M2115RCU may be installed either indoors or outdoors.
Considerations about antenna placement, power input availability and relay connection requirements
should be taken into consideration when selecting a suitable installation location.
(*
Note
: See installation
instructions for each model listed for individual recommendations.)
NOTE
: When the M2115RCU is mounted outside, a location should be selected so that the antenna
is not “shadowed” by buildings or other obstructions in the direction from which aircraft may approach.
For maximum radio range, mount the antenna as high as practical. For outdoor operation use, a
optional NEMA enclosure is required. Application of a waterproof sealant over external coaxial
connectors is recommended along with all electrical wires connecting between the internal relays and
external equipment.
Configuration
: This step is only required if the unit is not configured at the factory or if changing the
configuration dip switches is required. Connecting a PC to the enclosed DB-9 serial communications
port will allow the user to change the operating frequency. NOTE: only authorized persons are
allowed to change the operating frequency in the computer program. Access to this functionality is
password protected. The PC software also allows the user to test the new dip switch settings before
physically changing the switches on the radio control unit. Once the relay performance is verified the
new switch settings are to be made permanent, click the button “Get Physical Dip Switch
Settings.”(NOTE: 8.333Hz channel spacing requires 2 software programs to set the functionality; one
for setting the frequency and the other to set the performance “dip switch” settings.) Both are included
on the CD that is included with each unit.
Testing
: After configuration, test the controller using the “Test” button in the PC board.
Installation for each model M2115RCU is as follows:
M2115RCU-BNC
1. Choose a location where:
No metal or other conductive particles could come in contact with the printed circuit
board of the M2115RCU-BNC radio control unit.
No fluids could splash onto printed circuit board of the M2115RCU-BNC.
Unit will not be exposed to severe temperature changes. (near furnaces or air
conditioners)
2. Connect relay and power wires to green connector. If unit is configured for AC power,
connect your power ground to the plate ground stud.
3. Connect antenna to printed circuit board BNC RF connector using adapter (included).
