- PK232SAT.5
- All you need do is wire in 3 double throw switches with the center pins of
- JP4, JP5 and JP6 connected to the center lugs of your double throw switches.
- Then wire the inside and outside pins of JP4, JP5 and JP6 to these switches
- so that the JP center pins are switched to the inside pins for the internal
- PK-232 modem or to the outside pins for your external modem. These
- switches can be mounted on the front panel where space permits (like the
- upper right corner under "model PK-232"). To ease future servicing I
- recommend not soldering directly to the pins on JP4, JP5 and JP6. Check
- your catalogs (or local electronic supply store) for DIP connectors that
- are .100 center/.040 square hole size and wire your switches to them. Be
- sure to mark each connector so you'll always reconnect them to the correct
- pins in the future. A look at the PK-232 schematic will clearly show
- you what you are doing. A triple pole double throw switch would be nice
- if you can find one. I made do by ganging a SPDT and DPDT together.
