1. A device for use with a liquid accommodation container that is configured to be mounted in an accommodation section of a printing apparatus having a printing head, the device configured to electrically couple to a plurality of terminals associated with the liquid accommodation container, the device comprising:
a processing unit;
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.
