This manual details the operation of the DigiShot®Plus 4G Commander System.
Only trained personnel, and personnel found competent, are allowed to operate the system.
Users of the system shall be aware of the recommended procedures for using the DigiShot®Plus 4G
Commander System as per manufacturer’s recommendations.
These recommendations do not supersede the method as required by local mine, explosives or statutory
regulations/procedures/codes of practise regarding the use of detonators. In such cases, the MOST
STRINGENT set of rules between the mine, explosives or local regulations/procedures/codes of practise and
the manufacturer must be followed.
Training and software upgrades shall only be performed by a DetNet SA subject matter expert.
Contact the DetNet head office for additional information.
ALL USERS OPERATING THE DIGISHOT®PLUS 4G COMMANDER SYSTEM SHALL HAVE SUCCESSFULLY
COMPLETED THE SPECIFIC TRAINING BEFORE PERFORMING ANY WORK WITH THE DEVICE(S).
This manual is only to be used for the DigiShot®Plus 4G Commander System and the
applicable software version as displayed.

DetNet safety philosophy is to design, manufacturer and provide control equipment, detonators and accessories to
the highest safety standards.
•Energy management in control equipment will be regulated by providing two separate circuits managing
test voltage and blast voltage, through software and hardware safety interlocks.
•BlastCards remain in possession of the accountable person and should only be used to authorize the blast
process at such a time as stipulated by the Mine after completion of the required Risk Assessment.
•All products must conform to local and international standards before it is sold for use.
•DetNet complies to ISO 9001, SANS 551:2009, CEN/TS 13763-27 which is acceptable to countries we
operate in; in countries not subscribing to the above marks, we advise users to engage with DetNet to
ensure that all equipment comply to local regulations.
Safety is ensured when the user supplements the product’s in-built safety systems through adequate training in the
safe use of the product:
•Induction training
•Refresher training
DetNet continuously upgrades software to make the products more user friendly and to ensure that users stay
abreast on latest developments, it is important that users get trained on the relevant changes before their
equipment is updated.
Inherent Safety
•CE4 Taggers are “Inherently Safe” because they cannot produce the necessary minimum required firing
voltage or encoded “Fire” command to initiate the electronic DigiShot®Plus 4G Detonator.
•In addition, the CE4 Tagger firmware does not contain the procedures or commands necessary to calibrate,
arm or fire the detonator.

The purpose of this section is to indicate the recommended care and handling of the Commander System’s control
equipment considering the environment in which it is used. Proper care and maintenance of the equipment will
preserve the integrity and ensure its proper functionality. Poor handling and abuse of the equipment could result in
errors and potential blast delays.
The Commander System equipment must be transported, stored, handled and
used in conformity with all federal, state, provincial, local laws and regulations.
Control equipment and accessories should be handled with due care and not
dropped, mishandled, subjected to excessive vibration or exposed to harsh
chemical agents, including solvents.
The Commander should always be stored in the provided suitcase when not in
use, and especially during transportation.
Connectors should be kept clean and the equipment must be kept in a safe
environment to avoid misappropriation or misuse.
The Commander (Bench and Base) should be mounted on the supplied foot or
a tripod for reliable RF connectivity
All equipment in the field will need to be returned to DetNet South Africa, or an authorised repair centre, for
service at the following intervals:
Handheld Equipment (Tagger, etc.) –18 Months.
Other equipment (Commander, etc., Excluding accessories) –24 Months.
Any unauthorised repairs, modification or tampering of the device may comprise the safe operation of CE4
Commander system and is prohibited.
The CE4 Commanders are installed with a ShockWatch which will be activated if the equipment is
mishandled. In the event the ShockWatch is activated, it must be returned to DetNet SA or an authorised
repair centre for assessment.
Keep USB ports sealed, using the provided rubber door, to ensure no moisture or dust ingress. Inspect the
USB ports on an ongoing basis to ensure that moisture or dust / grit does not accumulate behind the rubber
door as that could lead to corrosion of the connector. Should any signs of damage or poor sealing be
observed, the equipment must be returned for repairs. An Air Duster can be used to remove dust from the
USB charging socket.
Periodically check the battery Cell Status indicator displayed on the System Information screen. ‘Good’
indicates a healthy battery state. Should the status indicate ‘Low’ the unit should be serviced to have the
battery replaced.
General cleaning of equipment will be required when exposed to the mining environment. Use a damp cloth
or preferably baby wipes and a brush to remove dust and any residues.
Use of cleaning solvent is not advised as this can cause degradation and permanent damage to the
equipment. Refer to solvent manufacturer’s TDS for compatibility information.
Inspect the Terminals on the Tagger and Commanders ensure that the spring contacts are functional and
free from dirt and residue. Excessive corrosion on the terminals can result in poor electrical connections. If
damaged, the equipment must be returned for repairs.
As the Tagger contains a Li battery, industry standards and precautions should be followed during charging
of the equipment. Disposal of the equipment and battery is not permitted, and the equipment must be
returned to the supplier in the country for recycling and proper disposal.

The system description details a full system lay-out and also the individual component name, function and interaction
between the components. The picture below shows the system components.
This 4th generation Control Equipment (CE4) that is designed and developed by DetNet South Africa consists of two
main devices, namely the DigiShot®Plus 4G Commander and CE4 Tagger. The DigiShot®Plus 4G Commander unit
may be set-up either as a Bench Commander (for connection to detonators) or as a Base Commander that is used
to remotely communicate with a Bench Commander to initiate the blast (see illustration below). The Commander
may also be used as a RF Repeater to increase remote blasting range and maintain line of sight.
The CE4 Tagger is an inherently safe device that is used on the bench to test detonators and assign delays to them.
The CE4 Tagger has a dual role and may also be used to wirelessly connect to a DigiShot®Plus 4G Commander
thereby acting as an interface unit for the DigiShot®Plus 4G Commander.
This unique design simplifies the design of the DigiShot®Plus 4G Commander –which comprises of a screen and
two buttons allowing the user to control the DigiShot®Plus 4G Commander remotely from the comfort of a CE4
Tagger.
Peripheral devices such as a Laptop or Tablet will be COTS (Commercial Off-The-Shelf) equipment loaded with
DetNet software to interact with the system.
Figure 1 (below) depicts a scaled system as would be required to perform a 1600 detonator blast (Using 10
Commanders each connected to 1600 detonators the blast size can be increased to capacity of 16 000 detonators)

Multiple Bench Commanders can be used if they are within the 3000m range of the Repeater (5). Every Bench
Commander (4) adds a 1600 detonator capability. A maximum of 10 Bench Commanders may be used for the
current iteration of the DigiShot®Plus 4G Commander System.
