11.4. The Setting Method of JIG (Handset)
11.4.1. Preparation
11.4.1.1. Equipment Required
• DECT tester: Rohde & Schwarz, CMD 60 is recommended.
• Frequency counter: it must be precise to be able to measure 1 Hz (precision; ±4 ppm).
• Frequency counter: it must be precise to be able to measure 1 Hz (precision; ±4 ppm).
Hewlett Packard, 53131A is recommended.
• DC power: it must be able to output at least 1 A current under 2.4 V for Handset.
• Digital multi-meter (DMM): it must be able to measure voltage and current.
• Oscilloscope
• Digital multi-meter (DMM): it must be able to measure voltage and current.
• Oscilloscope
11.4.1.2. JIG and PC
• EEPROM serial JIG
JIG Cable: PQZZ1CD300E*
• PC which runs in DOS mode.
• Batch file CD-ROM for setting: PQZZTG7125RU
• Batch file CD-ROM for setting: PQZZTG7125RU
Note:
*: 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
(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.)
11.4.2. PC Setting
11.4.2.1. Connections
Connect the DC Power or Battery to J1 and J2 (Handset).
Connect the JIG cable GND (black).
Connect the JIG cable UTX (yellow) and URX (red).
Note:
*: Com port names may vary depending on what your PC calls it.
