3.2.1 Optocoupler Input Voltage
The interface to the external digital actuators is achieved with optocouplers that incorporate overvoltage
protection. The nominal voltage to switch the optocouplers is 12/24 VDC. This voltage can either be supplied
externally into the receiver, or via the internally-available power supply.
3.3 External Antenna (standard)
The controller usually includes an external RF antenna attached the receiver housing. Ensure that the controller is
installed in a location where line-of-sight exists with the receiver, and that the system does not exceed the
maximum distance between the units.
3.4 Detached Antenna Kit (optional)
If the controller is supplied with an antenna kit to install the antenna detached from the receiver housing, install
the antenna in a suitable location following the supplier's instructions. Run the coaxial cable from the antenna to
the controller and connect it to the external antenna connection point. Ensure that the coaxial cable being used
does not exceed the maximum allowable attenuation for your application, as this might reduce the range of the
system.
3.5 TransKey
Verify that the controller TransKey (black) matching the receiver TransKey (yellow) is placed in the appropriate
holder inside the controller enclosure. Each TransKey pair is marked with a unique system address.

Note: Do not interchange the TransKeys for the controller (black) and the receiver (yellow). If the
TransKeys are interchanged, the system will not operate.
3.6 RF Channel Selection
In order to ensure interference-free radio control system operation, choose an undisturbed RF channel. Since the
RF channel is typically set by the manufacturer, it should be determined before shipping the system to the
customer’s site.
3.6.1 Changing the RF Channel
Due to interference from other systems, it may be necessary to change the RF channel preset by the
manufacturer. The RF channel can be changed by reprogramming the TransKey. This is typically done by the
manufacturer or can be done on-site with an appropriate programming adapter and software.
Note: When changing the RF channel, be sure to observe the country-specific regulations regarding
frequency range and channel.
