This chapter explains the measuring equipment, the JIG connection, and the PC setting method necessary for the measurement in 
 Troubleshooting Guide (P.29)

• 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.

<Preparation>

• Serial JIG cable: PQZZ1CD300E*
• PC which runs in DOS mode
• Batch file CD-ROM for setting: Refer to parts list of Fixtures 

*: If you have the JIG Cable for TCD500 series
(PQZZ1CD505E), change the following values of
resistance. 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.

 Connect the JIG Cable GND (black).
 Connect the JIG Cable RX (red) and TX (yellow).

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

Command name

Function

Example

rdeeprom

Read the data of EEPROM

Type “rdeeprom 00 00 FF”, and the data from address 
“00 00” to “FF” is read out.

readid

Read ID (RFPI)

Type “readid”, and the registered ID is read out.

writeid

Write ID (RFPI)

Type “writeid 00 18 E0 0E 98”, and the ID “0018 E0 0E 
98” is written.

hookoff

Off-hook mode on Base

hookon

On-hook mode on Base

Type “hookon”.

getchk

Read checksum

Type “getchk”.

wreeprom

Write the data of EEPROM

Type “wreeprom 01 23 45”. “01 23” is address and “45” 
is data to be written.

epc

Write memory size

Type “epc”. 

idwrite

Write ID

Type “idwrite”. Then enter ID code. 

 Insert the Batch file CD-ROM into CD-ROM drive and 

   copy PNZZTG**** folder to your PC (example: D drive). 

 Open an MS-DOS mode window.

 At the DOS prompt, type "D:" (for example) to select the

    drive, then press the Enter key.
  

 Type "CD 

㪳PNZZTG****", then press the Enter key.

 Type "SET_COM=X", then press the Enter key 

(X: COM port number used for the serial connection on your PC).

 Type "READID", then press the Enter key.  

   

䊶If any error messages appear, change the port number or 

  

䇭check the cable connection.

   

䊶If any value appear, go to next step.

 Type "DOSKEY", then press the Enter key.
