Motorola AP-7131 power and console connectors

Motorola isn’t very helpful in documenting various connectors on their business units, such as the AP-7131 wi-fi access point. So here you go…

The Power Connector

The power requirement of a AP-7131 is 48V DC, 0.7A (thus a minimum of 35W). The socket is a 4-pin male socket. It is exactly the same as the auxiliary 12V connector on an ATX board. A connector salvaged from a burnt out power supply will fit perfectly.

As it turns out the pinout of the AP-7131 power socket is exact opposite of the ATX one. Learned it the hard way (more on that later).

The pinout is:

  1. Two at the top:  GND
  2. Two at the bottom: +48Vdc

The Console Connector

The Console connector is similar to that of Cisco, with just a minor difference. Ground, Rx and Rx are the same, so a Cisco cable will work, if hardware flow control is disabled.

The pinout is:

  1. ?
  2. – not connected –
  3. Tx
  4. Gnd
  5. Gnd
  6. Rx
  7. – not connected –
  8. ?

Note: I didn’t bother figuring out the hardware flow pins.
