Hewlett Packard, 53131A is recommended.
· Digital multi-meter (DMM): it must be able to measure voltage and current.
· Oscilloscope
15.2.1.2. JIG and PC
· EEPROM serial JIG
JIG Cable: PQZZ1CD300E*
· PC which runs in DOS mode
· Batch file for setting: PQZZTCD220SL

Function
Read the data of EEPROM
Read ID (RFPI)
Write ID (RFPI)
Adjust Frequency of RFIC
Off-hook mode on Base
On-hook mode on Base
Read checksum
Write the data of EEPROM
Note:
*: If you have the JIG Cable for TCD500 series
(PQZZ1CD505E), change
resistance. Then you can use it as a JIG Cable for both
TCD300 and TCD500 series. (It is an upper compatible JIG
Cable.)

Example
Type "rdeeprom 00 00 FF", and the data from
address "00 00" to "FF" is read out.
Type "readid", and the registered ID is read out.
Type "writeid 00 18 E0 0E 98", and the ID "0018 E0 0E
98" is written.
Type "setfreq nn".
Type "hookoff".
Type "hookon".
Type "getchk".
Type "wreeprom 01 23 45". "01 23" is address and "45"
is data to be written.
