INTRODUCTION SJ GR-12L/ GR-12Li/ GR-12Lm HoTT receivers are compatible with SJ T series transmitter and used to airplane, helicopter and glider. HoTT system gives user real-time information on various useful data such as user model‟s RPM, voltage, temperature, user programmable warning, and so on which are directly obtained from telemetric speed controllers equipped with this HoTT system without having to install separate sensor devices. Of course, all of those telemetric data can be also transmitted from separate sensor devices. The use of up to 75 hopping channels provides advanced reliable operation while keeping from any external interference. All instructions, warranties and other collateral documents are subject to change at the sole discretion of SJ INCORPORATED. For up-to-date product literature, visit http://www.openhobby.com and click on the support tab for this product WARNING: Read the ENTIRE instruction manual to become familiar with the features of the product before operating. Failure to operate the product correctly can result in damage to the product, personal property and cause serious injury. FLYING SAFETY • Do not fly your model near spectators, parking areas or any other area that could result in injury to people or damage of property. • Ensure that all channels are working in the proper manner. • Perform a ground range check prior to the initial flight of the day • Do not fly during adverse weather conditions. Poor visibility can cause disorientation and loss of control of your aircraft. Strong winds can cause similar problems • We strongly recommend to set the Failsafe function and also recommend that the preset Failsafe would be idle position • You need to set the function of the transmitter after removing a power battery from a model or stopping a engine of a model. • Ensure that all your batteries have been properly charged prior to flight. GENERAL INFORMATION 1. Products • GR-12L : Normal Rx 6ch 2. Features • The use of up to 75 channels ensures extreme operating reliability and immunity to external interference. • High bright LED allows to check the operating status • The optimized sizes and weights • Receiver input sensitivity and thus the range have been increased further. • Servo connections in the front panel. • Failsafe, Hold, OFF, and standard (channel 1 failsafe; all others hold) programmable.
3. The Specification When turning on or adjusting the radio control system it is essential to keep transmitter antenna at least 30 cm away from receiver antenna all the time. If transmitter antenna is too close to receiver antenna, receiver will be overloaded and the red status LED on receiver blinks red. Transmitter responds by repeating a single beep every second and the radio control system is entered Fail-Safe mode. If the distance of the antennas between transmitter and receiver would be simply longer than 30cm in this situation, the beep of transmitter is ceased and the red status LED on the receiver turns off 4. LED indicator You may check the signal reception according to status LED • LED off : Very good reception • LED blinking : Poor reception • LED on : No signal reception OPERATION 1. Binding • GR-12L Turn on receiver‟s power and press Bind button on receiver for 3 seconds, the red status LED turns off. Follow the procedures of your specific transmitter to bind, the system will connect within a few seconds. NOTICE: Once transmitter and receiver are connected, the red status LED on the receiver is off, indicating the receiver is bound to the transmitter. If the binding process has failed, repeat the whole procedure. • Binding a number of receivers in one model It is possible to bind a number of receivers to a transmitter in one model. Every receiver must be bound to the transmitter individually according to the procedure already described. The last bound receiver is the master receiver when the system is in use. Every telemetry sensors installed in the model must be connected to the master receiver, since the only master receiver transmits the sensor data through the downlink channel. The second and all further receivers are operated as the slave mode which are connected in parallel to the master with the downlink channel switched off. The control signals can be passed to a number of receivers simultaneously and also the different signal can be assigned to each receiver through the channel mapping function of the transmitter or the optional TELEMETRY BOX. The typical example would be the use of two servos for each aileron, etc. Parameter Spec Channel 6 Frequencies 2.400 – 2.483.5 GHz Modulation FHSS spread spectrum Input Voltage 3.6 ~ 8.4V Display Indicator One LED(red) Upgradable Firmware Yes(CH5) SUMD Signal Yes(CH6) Fail Safe Hold/Fail safe Ch mapping Yes
2. Channel Mapping Access Receive CH mapping on transmitter then you may change to the desired channel 3. Range check Before every flying session and especially with a new model, it is important to perform a range check. All SJ aircraft transmitters incorporate a range testing system which, when activated, reduces the output power, allowing a range check. Notice that every flying must not be permitted in the range checking mode and the model is restrained on the ground. After binding the receiver to the transmitter, turn on transmitter‟s power first and then turn on receiver‟s power. Make sure that the system is operating normally through servo movement. • Mount the bound receiver in the target place in the model. • Turn on the RC system so that you could observe the movement of the servos. • Put the model on a flat surface (pavement, closely mown grass or earth), and ensure that the receiver antenna should be at least 15cm above from the ground. • Face the model with the transmitter in your normal flying position, the antenna on the transmitter shouldn‟t be toward the model directly and it keeps stand horizontally during range checking • Enter range check mode of your specific transmitter and follow the procedures of your specific transmitter to check the range. the transmitter repeat a single beep with a regular rhythm, indicating the Range checking is processed normally. • Walk over 50 meters away from the model with controlling the transmitter sticks constantly and check whether the model is operating normally. You should have total control of the model with the trainer switch pulled • If control issues exist within 50 meters, the system should not be used. And contact your local Service Department of SJ INCORPERATED. • Range-check is automatically terminated in 90 seconds and it is also terminated by turning off the range check function of your specific transmitter. the red status LED on receiver turns off when terminated. • Have your helper position the model and check effective radio range before every flight while simulate all the servo movements which will take place when the model is in fight. The ground range must always be at least 50m in order to ensure safe and reliable model control. CAUTION: During normal operations (i. e. when controlling a model) never enter the range check mode ! 4. Fail-Safe function In its default state, the receiver is set to “Hold” mode. If you lose connection, all channels hold last given command and the status LED on the receiver turn solid red. The transmitter also repeats a single warning beep every second. You can use the fail safe option by programming the throttle channel to respond to a fail-safe situation. : the throttle channel of an engine-powered model should be set to idle, the throttle channel of an electric-powered model to “stop”, and the throttle channel of a model helicopter to “Hold”. When a signal is lost the throttle channel, all channels are driven to the failsafe position so that it could prevent the model crashing and the personal injury or property damage.
5. Range warning Since the transmitter‟s output is much higher than that of the receiver, the user tends to be hard to notice the seriousness of the situation and try to keep full control of the model. So when the receiver signal in the down-link channel becomes too weak, the transmitter repeats a single warning beep every second. You should fly back the model towards the safe place until the warning signal ceases. If the beep warning does not cease when you fly back, it is that the transmitter or receiver low voltage warning or temperature warning is activated, you must land the model and cease operations without delay in this situation. RECEIVER 1. Servo connection Plug the servos into the row of sockets on the right end of the receiver. The connector has polarity, note the small chamfer on one edge. The socket polarity is also marked on the case, brown wire (-), red (+) and orange (signal).The servo sockets of the receiver are numbered and one of the sockets, from channel 1 to 6, can be used as the battery socket, and also both of the receiver power supply and the servo can be connected to it in parallel with Y-lead. Especially the channel 6 that is used for the sum signal could be programmed by the TELEMETRY BOX. When using High Power servos, connect the receiver power supply to one of the sockets, from channel 1 to 6, with Y-lead • Receiver socket • Receiver channel 2. Telemetry socket The channel 5 has “T” mark which means Telemetry interface. Telemetry interface with the optional telemetry sensors, the latest firmware updating with the USB interface and the programming with the SMART BOX could be processed. If the telemetry sensors are connected to the socket of the channel 5, a servo is no longer work in this socket. When using receiver GR-12Li (JST ZHR-3 Conn) or GR-12Lm (SHR-03V-S-B Conn), the adapter cable is also needed.
