Frequently Asked Questions

What is a microterminal?

We can say that a microterminal is a device that streamlines processes at the point of sale, like a programmable keypad.

How do I configure the IP and serial ports of the MT 720?

To configure the microterminal, connect an external keyboard to the device’s AT port. Turn on the device and press the P key on the external keyboard during startup. Make the necessary modifications and don’t forget to save the new configuration
