With the telemetry system, the running status can be displayed at the transmitter and
also recorded as a data log by mounting various sensor units to the chassis.
The telemetry related screens are only displayed when the T4GRS power switch is in the
PWR ON position. When the power switch is in the DISP position, the telemetry related
screens are not displayed.
The T4GRS displays four kinds of information on the HOME screen;
receiver power source (battery) voltage, external power supply (drive bat-
tery) voltage, speed, and temperature.
*The telemetry function is compatible with only the T-FHSS system.
*The telemetry function requires a corresponding receiver (R304SB,R304SB-E).
*Only T4GRS with R304SB(-E) ID registered have a telemetry display.
*Multiple sensors of the same type cannot be used.
The sensor data can be checked at the transmitter by connecting
the telemetry sensor sold separately to the S.BUS2 connector of
the R304SB(-E) receiver.
The figure is an example of connection of a telemetry sensor. The data of up to the fol-
lowing 3 types of sensors and the receiver power supply voltage can be transmitted by
using the 3-way extension cord or double extension cord sold separately.
The receiver power supply can also be connected to the S-BUS2 connector or each of
CH1-4. A receiver power supply voltage sensor is unnecessary.
*The S-BUS2 system exerts control by connecting multiple gyros, servos and other devices corresponding to one S-BUS2
connector. Each device is separately controlled by setting the channel No. or slot No. individually for each device.
A slot No. is also set for telemetry sensors. With the T4GRS system, each slot No. of a telemetry sensor must be set to its ini-
tial value. Since the slot No. can be changed for other aircraft type transmitters (T18MZ, etc.), sensors with changed slot No.
will not operate if not returned to their initial slot No. When using a sensor that is used with transmitters other than a T4GRS,
whether or not the slot No. is set to the initial value given in the sensor instruction manual must be checked at the changed
transmitter (T18MZ, etc.). With the T4GRS, the set slot No. cannot be checked or changed. So, essentially, if a sensor has
been used in an 18MZ, and you want to use the same sensor with your T4GRS, you must first change the slot number through
the 18MZ or it will not work in your T4GRS.
