The Main Cable Features:

• Connectible to PC COM port of 25 pins DSUB connector:
  - This connector include the electronics, which stand the spark arise from electrostatic charge (e.g. You work in synthetic fibre sweater or pullover), because not include IC (Integraded Circuit), than cable of other manufacturer. This electronic circuit convert the level of signal from one unit to another, because the signal of the CASIO units other type (TTL).
  - The supply voltage get in PC, battery not necessary to electronics, and spare the CASIO^® battery.
  - In package to be found the 25/9 pins converter, in case only 9 pins connector exists on PC.
