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 enough to measure intervals of 1 Hz (precision; ±4 ppm).
• Frequency counter: It must be precise enough to measure intervals of 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
• Serial JIG
JIG Cable: PQZZ1CD300E*
• PC which runs in DOS mode.
• Batch file CD-ROM for setting: PNZZTG7321UA
• Batch file CD-ROM for setting: PNZZTG7321UA
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
and TCD500 series. (It is an upper compatible JIG Cable.)
(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 BATT+ and BATT-.
Connect the JIG cable GND (black) to GND.
Connect the JIG cable UTX (yellow) to UTX and URX (red) to URX.
Note:
*: Com port names may vary depending on what your PC calls it.
