CONNECTOR J2 INFORMATION
For the TM-2025
For the TM-2030 it is a standard phone
plug and should present no problems. (see last paragraph previous page)
the plug that mates with the J2 on the Tm2025 requires
several different parts. The connector housing is Digikey stock number
H3785-ND or (Mfr: Hirose Electric) part number DF1B-6S-2.5RC.
Digikey H3828-ND or DF1B-
2022SC.
The pins for wire size 24-28: Digikey H3832-ND or DF1B-
2428SC
To crimp the wires to the pins a tool is necessary: for example: Radio
Shack catalog # 276-1595 works fine with a little care, for $10.
The pins for wire size 20-22: Hirose Electric
