= +11.4 ∼ +12.6V
= +4.75 ∼ +5.25V (Note 2)
= +4.75∼ +5.25V (Note 3)
= +4.75∼ VVD2 (Note 4)
= VDD1∼ +5.25V (Note 4)
= 0V
= 0V
= 0V
Note: 1. Each supply line should be distributed from the power supply unit.
2. JP9 (REG) should be open when the “+5V” jack is used.
3. JP8 (D-A) should be open when the “D5V” jack is used.
4. JP10 (VDD1) / JP11 (VDD2) should be open when the “VDD1” jack / “VDD2” jack are used
respectively.
2) Set-up the evaluation modes, jumper pins and DIP-switches. (Refer following sections.)
3) Connect the PORT3 (=µP-I/F) with PC by the enclosed 10-wire flat cable.
4) Set up the PC and execute the enclosed control software. (See “CONTROL SOFTWARE MANUAL”.)
