1 Introduction
The CDX Tablet Transceiver is a device used to transmit speed commands to the CDX EV Controller. See Chapter 4
(Technical data) for frequency and antenna details. The device is designed for installation at a fixed location with
an overview of the go-karting track. The CDX Tablet Transceiver provides a fixed control interface within the CDX
control system. The product is intended as a supplementary control device and does not replace established track
procedures and supervision.

1.2 Compatible expansion components
- CDX EV Controller
o The CDX Tablet Transceiver controls the CDX EV Controller to limit the speed on a go-kart.
- CDX Phone Transceiver
o The CDX Tablet Transceiver can control the CDX EV Controllers together with CDX Phone
Transceivers. Speed settings are automatically synchronized between the CDX Tablet Transceiver
and the CDX Phone Transceiver such that both are able to control and show the speeds of CDX EV
Controllers.
- Tablet stand
o The CDX Tablet Transceiver can be mounted on a tablet stand to allow you to perform other tasks
at a moment's notice. An example is signaling an accident using a flag, which requires both hands.

2 Operating instructions
The CDX Tablet Transceiver is used to send speed commands to the CDX EV Controller. Track marshals positioned
alongside the go-karting track monitor on-track activity and overall safety. If necessary, they can remotely adjust
the speed of individual go-karts or bring them to a complete stop by transmitting speed commands via the CDX
Tablet Transceiver.

2.2 Group speed control
Group speed control is used to activate a speed setting for all go-karts, within the range of the CDX Tablet
Transceiver. The group speed control buttons are shown in Figure 8, and highlighted with number 2.
2.3 Individual speed control
Individual speed control is used to apply a speed setting for a specific go-kart. The individual speed control
buttons are shown in Figure 8, and highlighted with the number 1. The speed of the individual go-kart will also be
displayed in this area.
For example, if all go-karts are set to speed 4, but kart 22 is individually set to speed 3, the remaining go-karts will
continue to run at speed 4.
2.4 Synchronization between Remote controls
All CDX Control interfaces (Tablet and Handheld) support synchronization functionality. When synchronization is
active, the current speed setting of the assigned group is displayed on each control interface. The displayed speed
setting can be found in the upper-left corner of the screen, next to the CDX Technology logo, referred to as S1 up
to S4 (or S8 if the 8 speed settings are used).
2.5 Charging
Charging starts when the charger is plugged into the USB-C charging connector on the bottom side of the CDX
Tablet Transceiver, which is shown with the number 4 in Figure 7. Please take notice that the CDX Tablet
Transceiver must be turned on in order to negotiate charging. Therefore, never let the charge go under 20 %.
Charging should only take place using the supplied charger and the supplied USB-C cable.

3 System Configuration
The CDX Tablet Transceiver has various features that can be configured. This includes 4 or 8 speed mode, Track ID
and Track PIN.
3.1 Speed restriction
The main function of the CDX Tablet Transceiver is to limit the speed of go-karts using the CDX EV Controller. This
is done using the group speed control buttons are shown in Figure 8, and highlighted with the number 1.
3.2 4 speed or 8 speed mode
When the motor speed controller on the go-kart uses 4 separate speed presets and a stop command, the CDX
Tablet Transceiver should be used in 4 speed mode. This is the default configuration. Optionally, for normal use
speed 1-4 and STOP can be send to the CDX EV Controller. An optional 5-8 speed is available for go-karts that
have a different motor controller. See the corresponding CDX Technology Europe B.V. (2026).
CDX_Remote_App_User_Manual. for further information.
3.3 Track ID and Track PIN
The Track ID and Track PIN feature allows the segmentation of a group of CDX EV controllers. By default the
Track-ID is set to ‘0000’ and Track-PIN is set to ‘0000’. In this mode the CDX EV controller accepts speeds
commands from CDX Tablet Transceivers remotes regardless of track id and track pin settings of the CDX Tablet
Transceiver. This is done to enhance the safety where someone cannot accidentally block their communication
ability.
A Track ID and Track PIN can be used when individual control of two or more groups of go-karts is required. The
Track ID and Track PIN are configured in the settings of the CDX Tablet Transceiver and must correspond to the
settings in the CDX EV Controller.
This function can also be used to prevent misuse of the system by changing these 2 parameters. Preventing
dangerous situations caused by people with malicious intent.
3.4 Region
Every CDX Tablet Transceiver is preconfigured to work with the radio frequencies that are permitted in the
specific region where it is bought. The region code is shown on the label of the CDX Tablet Transceiver, shown in
Figure 7, highlighted with the number 5.
It should be noted that the CDX Tablet Transceiver only works with other CDX devices configured to the same
region (frequency). Additionally, Transceivers are intended for use only in the region for which they are
configured.
