The Protel Keypad Adaptors adapt Protel keypads to Protel circuit boards when the keypad and board have different connectors. Two different DB keypad adapters are available, a 15 pin female to 25 pin male (15F-to-25M), and 25 pin female to 15 pin male (25F-to-15M).

If your keypad connector is a DB15 male and you need to connect it to a DB25 female connector such as a Protel 310 or Protel 7000, select the 15F-to-25M. If your keypad connector is a DB25 male and you need to connect it to a DB15 female connector such a Protel 200BB+/GTEL-1000, select the 25F-to-15M.
