15 Measurements and Adjustments
15.1. Cordless Base Section (Digital Board) Adjustment
When you have replaced EEPROM or BBIC or X’tal, adjustment is necessary.
This supplement will explain further details for adjustment.
15.1.1. Equipment Required
1. PQZZ1CD300E*
3 wire cable: It connect the Digital Board and PC.
2. PFZZFC265GR
Batch Files: it’s executed on PC.
Please copy “Base” folder in PFZZFC265GR (CD-ROM)
folder including Batch files to your PC.
3. PC
Input a command for adjustment.
4. Frequency Counter
It’s to adjust frequncy(10.368000MHz) of BBIC.
It requires an accuracy that can measure 1Hz. (precise;
±1ppm)
5. Digital multimeter
It’s to adjust voltage (1.8V) of BBIC.
Note:
*: If you have the JIG Cable for FC245 series (TCD500
series) [PQZZ1CD505E], change the following values of
resistance. Then you can use it as a JIG Cable for both
FC962 and FC245 series (TCD300 and TCD500 series). (It
is an upper compatible JIG Cable.)
15.1.2. PC Setting
15.1.2.1. Connections
At pins of CN2 on the back side of the digital board
Please connect the component and the cable as follows:
Refer to Adjustment Standard (Base Unit) (P.179).
*1: 10k resistor : Please put it between 1pin and 2pin and connect TX cable from PC. (ERDS2TJ103T or ERDS1TJ103T)
*2: 1k resistor : Please put it between 9pin and 2pin and connect RX cable from PC. (ERDS2TJ102T or ERDS1TJ102T)
*3: wire : Please put it between 11pin and 14pin (shorted) and connect GND cable from PC. (This makes a board 3 wire mode.)
*4: 2 wires : Please put it 12pin and 14pin. Please connect 2 wires after turning power on. (this makes reset)
