Assembling the DB-25/RJ12 Adapter and the Cable
Use the following procedure to wire the adapter and assemble the cable:
1 Obtain a male DB25 to female RJ12 adapter, such as the Voltrex
MAK206F (manufactured by SPC Technology) or equivalent, and either a
6-conductor male-to-male RJ12 cable of a suitable length or a similar
length of 6-conductor, flat telephone cable and two RJ12 plugs. RJ12
modular plugs (SPC part number TA30-6) and 6-conductor, flat telephone
cable (SPC part number TXW6151) are also available from SPC
Technology (and other manufacturers).
2 Adapter kits like the Voltrex MAK206F usually include a pre-wired RJ12
modular receptacle, a DB25F connector, and the adapter body, or wiring
shroud. Wire the RJ12 receptacle to the DB25F connector according to the
diagrams in Figure 3-3, and then assemble the adapter according to the
instructions included in the kit.
