2. Handling Precautions
• • • •
The bypass capacitor for the microcontroller (MCU) and power supply, the jumper plug
for switching the subclock, the jumper plug for switching the C terminal, and two
connectors for connection with the universal cable assembly are mounted on the probe
header. Be sure to read Section 3, "Using the Products," before using the probe header to
prevent incorrect cable connection, which could cause incorrect operation or product
failure.
• • • •
The MB2144-222 and MB2144-222-01 are precision-manufactured to improve
dimensional accuracy and to ensure reliable contact. These products are therefore
sensitive to mechanical shock, and must be handled carefully. To ensure correct use in the
appropriate environment, use the products only as instructed in Section 3, "Using the
Products".
• • • •
Because ports 0 and 1 of the MCU are connected with cables, they are susceptible to
noise. If ports 0 and 1 are used as input ports, drive the element connected to the ports
with a current of 1 to 2 mA when the port outputs an L level voltage. Be careful not to
read ports only with a pull-down resistor connected, because the values may not be
correctly read.
