Uniform DEX Standards For Effective Vending

In the current vending industry, vending operators are ready to blame the equipment manufacturers for not doing enough to standardize their DEX hardware and software. Certain people believe that the manufacturers did not adopt a set of standards and these are too broad.

Amongst others, Planet Antares vending operators want to see NAMA adopt more stringent DEX standards. Even several equipment manufacturers agree that standards can be improved to a certain extent. During their first attempt with utilization of DEX, some of the operators have had problems.

In certain cases, the DEX standards have been too broad. Out of these, the more stringent ones may be able to sort out the problems that are being faced by some Planet Antares vending operators. Manufacturers have indicated that not all machines require that same type of data. There is risk of extra cost in excessive standardization without providing any additional benefits.
Standardization will not always assure Planet Antares vending operators that manufacturers will abide by new protocols. Some manufacturers even claim that competitors have not supported existing DEX standards.

In itself, this is a judgment based on technical interpretation. Further, equipment manufacturers have pointed out that the task of gathering data in a usable form is one that should be handled by the software company only.

Even if additional standards are adopted by NAMA, manufacturers will add to that list for specific equipment needs. Whether minimum standards are essential to begin with is open to question, since many protocols are already being followed for the sake of convenience and simplicity.

Some DEX data tends to be standard in all vending machines including Planet Antares vending machines. These include:

Coin mechanical fields
Coin to tube
Coin to coin box
Coin from tubes
Total coins
Cash from validator
Total vends
Total cash
