- Whats up?
- I found an article in a back issue of 2600 (Spring 1996) on how to
- change the capacity of a CIDCO caller ID box. This file recaps
- some of that article and gives my own experiences.
-
- The Background...
- CIDCO is the primary brand of caller ID boxes around the country.
- Many other companies market CIDCO boxes under their own name.
- CIDCO boxes come in many different capacities ranging from 10 to 85
- callers. Most units have about 25 or 30. Since CIDCO is into mass
- production, its cheaper to produce one circuit board and just
- jumper (solder) what capacity they want. All the owner has to do
- is open the unit up and change the solder point. =]
-
- What Tools You Need...
- - A Cidco Caller ID Box Revision 1.2A to 4.1**
- To check the rev pop out the batteries, wait until the
- screen fades out and put them back in. It should say C-NAM
- 1.2A or C-NAM 4.1 or whatever. It should then display the
- capacity. If your capacity is 85 you probably can't
- increase the capacity any.
- ** This may work on other revisions. 2600 sez 1.2A or 1.4. It worked
- for me on 4.1. I'll bet they haven't changed much.
- - A soldering iron and basic soldering skills.
- - Optional: Multitester...helpful for testing the circuit before you put the thing
- back together.
-
- How to hack it...
- Turn the unit upside down and unscrew the two visible screws. Take
- off the battery cover. You'll see too more screws. Unscrew these
- (duh). There may be some more screws...you know what to do.
- Eventually you'll get to the circuit board. There should be a big
- chip in the middle. On one of the sides (left on rev 4.1) You'll
- see four sets of solder points labeled A - D. The functions depend
- on the Caller ID version.
-
- REV 1.2A
- This has a blue wire from the center chip to one of the
- following.
- A 10 numbers
- B 85 numbers
- C 10 numbers
- D 10 numbers
- Don't forget to put the wire on the same side of the solder pad you found it on
-
- REV 1.4
- Solder/Unsolder the points for the capacity you want
- (make sure only one pair is soldered)
-
- X2 C 10 numbers
- B 30 numbers
- A 60 numbers
- (none) 85 numbers
-
- R17 D French/English
- E Spanish/English
- F English only
-
- REV 4.1
- A 30 Numbers
- B 60 Numbers
- C 25 Numbers
- D 30 Numbers
- (none) 85 numbers {I think. I had to stop before it was tested I'll
- update this when I get a chance}
-
-
- In Conclusion...
- If anyone finds different combinations for different boxes, I'd be
- interested.
