Statement of Compliance FCC Compliance Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
Modular Approval Statement If you install the GC-205 transceiver inside of a vehicle, and you are not the final end user, FCC regulations require you to make the transceiver’s FCC ID easily visible to the end user.
Nomadio GC-205 OCU The GC-205 operator control system (OCU) is a 5-channel digital radio system. It is intended for use in driving small unmanned vehicles with on-board video cameras. The controller allows an operator to drive the UGV to the desired location, and then train the on-board camera on the point of interest.
Back Panel The GC-205’s Rear panel is arranged as follows: Bind Button Power Switch RS-485 Jack Antenna Jack Page 6 AA Battery Bays
Setting Up a Robot When the GC-205 transceiver is initially installed on a Bombot, the first task is to set the transceiver’s failsafe positions. Ensure that the wheels are not touching the ground. On power up, the robot will immediately go to failsafe positions: •If it powers up, and centers the steering wheels, and does not accelerate, then failsafes are correctly configured.

Transmitter Reference Batteries: The GC-205 Transmitter runs on 4 standard “AA” size cells. Alkaline, NiCd, or NiMH 1.5v cells may be used. LEDS: The transmitter has 3 LEDs that give basic feedback information. All three LEDs blink one after another when the transmitter is not connected to the receiver. Once connected the LEDs have the following meanings: •Link LED: Turns on when a link is established and flashes slightly to show activity. Turns off briefly to indicate a lost message.
Speed Switch: The Speed Switch limits the maximum operating speed of the vehicle by restricting the range of the Throttle Servo. The Speed Switch has three positions: •High: Throttle Servo moves through its full range of travel •Medium: Throttle Servo moves through 50% of its range of travel •Low: Throttle Servo moves through 25% of its range of travel The High position should be used when programming a connected Electronic Speed Controller.
Receiver Reference CAUTION: See “Setting Failsafes” before powering on the receiver for the first time on a robot. The factory defaults may not match the settings on your Electronic Speed Control: in this case the robot could run away when powered on. Whenever putting a new receiver on a robot, or resetting a receiver to factory default settings, the robot should be started with its wheels safely off the ground.

Appendix A: Transmitter Test Mode The transmitter has basic test code built into the application, mainly for checking the front panel connections. See Transmitter Setup for instructions on entering Test Mode. During the test procedure, any LED that is not specifically stated as being illuminated will flash briefly once per second. This is to make it clear that you are not in a normal operating mode. The RELEASE button is used to step through the test, implicitly testing it in the process.
