This chapter explains the measuring equipment, the JIG connection, and the PC setting method necessary for the measurement in 
 Troubleshooting Guide (P.24)

• Digital multi-meter (DMM): it must be able to measure voltage and current.
• Oscilloscope.
• Frequency counter: It must be precise enough to measure intervals of 1 Hz (precision; ±4 ppm)

Hewlett Packard, 53131A is recommended.

• DECT tester: Rohde & Schwarz, CMD 60 is recommended.

This equipment may be useful in order to precisely adjust like a mass production.

This section explains the PC setting to use command required in Check Point (Base Unit)(P.36).

<Preparation>

• Serial JIG cable: PQZZ1CD300E*
• PC which runs in DOS mode
• Batch file CD-ROM for setting: PNZZTG6481UA

*: If you have the JIG cable for TCD500 series
(PQZZ1CD505E), change the following values of resis-
tance. Then you can use it as a JIG cable for both TCD300
and TCD500 series. (It is an upper compatible JIG cable.)

 Connect the AC adaptor to DC-JACK (base unit).

 Connect the JIG cable GND (black) to GND.

 Connect the JIG cable RX (red) to URX and TX (yellow) to UTX.

*: COM port names may vary depending on what your PC calls it.
