Deltang Rx60 DSM2/DSMX Receiver for Land-Based Vehicles

Please take a look at this notice on Rx60 availability.

Rx60 DSM2/DSMX 13V 6 Channel Receiver with Bi-Directional ESC

Rx60 is a 6 channel (1.3A ESC, 5 aux chan) DSM2/DSMX compatible micro receiver designed for use in surface vehicle: cars, boats and train locomotives. The receiver is designed to operate from 3-13v DC. This allows it to be used with many battery combinations. 1S, 2S and 3S lipos are common choices (3S = 3 cells in series), 3-8 NiMH or a PP3. The motor output (H1) can supply up to 1.3A when the motor is stalled at 100% throttle.

The receiver is available as a bare board with 2.54mm pad space for ease of soldering and as a wired version. The latter has lead-out wires installed for battery and motor (H1).

Voltage Range:3V - 13V

Rx6x Receiver Features

Rx60 is intended for surface vehicles which require forward and reverse motor control. The H-Bridge bidirectional motor output is abbreviated H1. The H1 ESC (Electronic Speed Controller) has 256 step resolution in both directions (512 total). It controls speed with PWM which by default is set to its fastest (quietest) 16kHz setting.

The H1 configuration is determined by the selected receiver variant - see the Variants tab for details of each variant. The default for variants -2 and -22 is to control both speed and direction using channel 1, which is the throttle knob on Tx20, Tx21 and Tx22. If you prefer a full-range throttle control on channel 1 with separate direction switch on channel 3, then select the 'full-range and dir switch' option when specifying your receiver.

The H1 output can handle up to 1.3A current without heat sinking at voltages between 3 and 13V. Current is measured with motor stalled. The main constraint with current is heat in the receiver. Higher currents may be possible if a heatsink is added and is helped with the 120Hz PWM frequency. It should be possible to use it a little above 13V but this would require lower motor currents and/or heat-sinking. Induced voltages may be higher than the power source so it would not be wise to try to use it anywhere close to 20v.

P outputs are 'pads' with 'logic' or type outputs. Pads are simply solder points for controlling external things. Logic outputs are either on or off (also known as high/low and 3.3v/0v in voltage terms). The action can be inverted so 'On' can mean 0v or 3.3v. P outputs may also used to provide servo signals direct to the white/yellow lead on a servo.

P outputs can be used to directly control triggers on external sound cards. They may also used to drive LEDs with a series resistor to limit current to no more than 20mA. The behaviour of a P output can be configured by programming the receiver.

The Rx60 receiver is available in 7 variants to suit model usage and type of transmitter. 'Variants' are simply 'configurations' or combinations of receiver settings to match common needs. Although these are described as 'car/train/boat', any variant can be used for anything. All receiver settings can be changed in a process called 'programming'.

All versions of the Rx60 are the same hardware, the only difference is the program settings. The Rx60 settings can be changed in the usual fashion via waggling the sticks of a stick-type Tx or the PROG3 / PROG4 programmer may be used. A guide to Rx60 programming using a stick-type Tx is available here.

The 'Direction' feature in the table above indicates whether the receiver ESC uses the throttle (chan 1) as a centre-off or full-range control. Centre-off is the default setting for most variants. When configured for full-range (by programming), a seperate channel is used to set the ESC direction - this is channel 3 for the Tx2x controllers.

The default receiver setting is for the Low Voltage Cutoff (LVC) threshold to be determined from the voltage seen on initialisation - basically, the receiver firmware makes a 'guess' at the battery type. The algorithm used for this calculation means that a 9V Alkaline or NIMH battery can often be interpreted as an almost discharged 3S LiPo. The solution is to either disable LVC, or set it to the correct value for your battery; this is done by programming the receiver.

Instructions for programming receivers using your DT transmitter are at the bottom of the information leaflet that came with the transmitter.

The receiver programming steps for LVC are:

disable LVC: 7 2 1
set LVC: 7 2 3 units tenths

e.g. to set the LVC to 6.5V, the programming steps are: 7 2 3 6 5

The basic form of the the Deltang receivers is a bare board with solder pads for you to add your own wiring. As not all modellers are able to attach wires to the tiny circuit board pads, several wiring options are available to simplify the installation. Please contact us to discuss your needs if one of the options, described below, is not ideal.

If you select one of the wiring options, and that is all you need for connecting the receiver into your vehicle, you should also select the heat shrink tube to be applied to the receiver. Otherwise, a length of heat shrink tube is provided for you to apply yourself.

Power & Motor Lead-Outs
100mm bare-end lead-out wires on the battery input and motor output using appropriately sized flexible wire, red/black for the battery input and yellow for the motor output.
Power, Motor & L Lead-Outs
Same as above plus grey lead-out wire for the 'L' pad. This option must be selected if you are using a single LiPo cell with voltage booster. The 'L' input allows the receiver to monitor the LiPo cell voltage and implement motor-cutoff when the cell is discharged.
