Problem 1: 68HC16MOD-16WIDE not found (see
Figure 5).
• Is LED1 on the 68HC16MOD-16WIDE lit?
• Is the power supply connected?
• Is SW1 turned to ON position?
• Is the DB9 serial-communications cable connected?
• Could another application be using the COM port
Problem 2: Cannot read data from MAX1308 EV kit.
• Are JU5–JU12 set for buffered or unbuffered inputs?
• Are the buffer power supplies (HVAVCC and
• Are the MAX1308 EV kit power supplies (AVDD and
• Are JU4 and JU14 set for internal or external clock?
• Is the part in shutdown mode?
Problem 3: Data being read from the MAX1308 seems
incorrect.
• Are JU1 and JU13 set for bipolar or unipolar inputs?
• Is the reference voltage entered correctly in the
• Is the midscale voltage entered correctly in the
• Is the correct part selected in the MAX1308 evalua-
• Is the source impedance less than 100Ω?
