Detnet TDS-00021 Commander System Technical Data Sheet
COMMANDER SYSTEM TECHNICAL DATA SHEET
Product Description
This 4th generation Control Equipment (CE4) designed and developed by DetNet South Africa consists of two principal devices, namely the CE4 Commander and CE4 Tagger, as well as various other system components interacting to facilitate safe testing and blasting of electronic detonators.
Technical Data
CE4 TAGGER
The CE4 Tagger is an inherently safe multi-functional device that can be used for on-bench operations such as assigning detonator times, testing communication, testing leakage of detonator installation, and verification of desired blast layout. The CE4 Tagger is inherently safe as its battery and output voltage are below minimum firing voltage of the detonator and the Tagger cannot issue the encrypted blasting commands (i.e. ARM and FIRE commands).
The CE4 Tagger interfaces via an encrypted Wi-Fi communication link with the Bench and Base Commander. The Base Commander will then instruct all connected and enabled Commanders with the blast instruction via the BlastCards (NFC Card).

CE4 COMMANDER
The CE4 Commander is a 4-channel multi-functional device intended for use across all surface blasting platforms in the DetNet portfolio and can be configured to function as a Base Commander, Bench Commander, RF Repeater as well as a D-GPS Base Station if the GPS Receiver hardware within the Commander is activated. The CE4 Bench Commander can be used directly for Local blasting or via the CE4 Base Commander for Remote blasting.

OTHER
Commander System control equipment batteries should be kept in a charged state. It is recommended that the Commander be charged to 50% when placed into long-term storage, and thereafter the unit should be charged at least every six months to 50%, to maintain the expected lifetime of the battery. All equipment in the field must be returned to DetNet or its approved repair centres for service at the following intervals:
