Abstract
A device outputs a first low voltage to a first terminal at a first timing in a period in which a voltage input to a second terminal is a high voltage. After outputting the first low voltage, the device outputs a second high voltage to the first terminal at a second timing in a period in which the voltage input to the second terminal is a low voltage. After outputting the second high voltage, the device outputs a second low voltage to the first terminal at a third timing in a period in which the voltage input to the second terminal is a high voltage.

A printing system comprising:
- a printing apparatus;
- and
- a liquid accommodation container that is configured to be mounted in an accommodation section of the printing apparatus, wherein
- the printing apparatus includes
- a printing head, and
- the accommodation section, the accommodation section including:
- (i) a liquid introduction portion that introduces a liquid to the printing head, and (ii) a plurality of apparatus-side terminals,
- the liquid accommodation container includes
- a liquid accommodation body configured to accommodate a liquid,
- a liquid supply portion that is mounted at the liquid introduction portion of the printing apparatus and includes a liquid supply port for supplying a liquid to the liquid introduction portion from the liquid accommodation body,
- a device configured with a processing unit, and
- a plurality of terminals electrically coupled to the device and configured to contact the plurality of apparatus-side terminals;
- wherein, when the liquid accommodation container is mounted in the accommodation section and a data terminal of the plurality of terminals does not have a short circuit with other terminals of the plurality of terminals, the processing unit is configured to:
- receive from a clock terminal of the plurality of terminals a clock signal that alternates between a low clock voltage and a high clock voltage at the clock terminal;
- and
- set a combination of data voltages at the data terminal at a first time, a second time, and a third time associated with the clock signal;
- wherein the first time is during a period in which the clock signal at the clock terminal is the high clock voltage, the second time is later than the first time and is during a period in which the clock signal at the clock terminal is the low clock voltage, and the third time is later than the second time and is during a period in which the clock signal at the clock terminal is the high clock voltage;
- wherein the combination of data voltages includes a first data voltage lower than a reference data voltage at the first time, a second data voltage higher than the reference data voltage at the second time, and a third data voltage lower than the reference data voltage at the third time;
- and
- wherein the combination of data voltages indicates to the printing apparatus that the liquid accommodation container is mounted in the accommodation section and that the data terminal does not have a short circuit with the other terminals.
