This telemeter's onboard computer collects data from vending machines, such as remote DEX, sales information, alerts, and alarms. It can create a wireless network, if necessary, and replace the machine's DEX port so that a handheld device can interface with the system. When a radio unit is installed, along with its antennas, the unit uses two-way communications to transmit and receive data to verify and complete cashless sales. It also transmits and receives data about the vending machine’s current sales and service condition.
