1. Checking the Delivered Product
Before using the MB2144-227-01, confirm that the following components are included in the product
package:
*1: Manufactured by Tokyo Eletech Corporation
*2: Include with 4 screws for securing HQPACK (M2 × 6 mm, 0.4 mm pitch).
*3: Screws for securing prove header can be interchangeable with screws of M2×8 mm, 0.4 mm
pitch.
2. Handling Precautions
• The MB2144-227-01 is 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 4 "Using the Products" and Section 5 "Connection".
• The bypass capacitor for the microcontroller (MCU) and power supply, 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 4 "Using the Products" and Section 5
"Connection", before using the probe header to prevent incorrect cable connection, which could
cause incorrect operation or product failure..
• 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.
