It really depends on what signals are on the RJ-45 connector. I doubt
that it's ethernet, but it might be. My guess(tm) is that it's
RS-232, RS-422, or RS-485 serial. Since you apparently don't want to
reveal the manufacturer or model number, I can't tell from here.

If it's ethernet, it's highly likely that any "wireless client bridge"
will do the trick. Here's a list or probable culprits.

If it's serial, it can still be done, but will require some
specialized software on whatever computah is controlling this device.
See the wireless to serial module at:
<http://www.lantronix.com/device-networking/external-device-servers/wibox.html>
There are others. Depending on peformance requirements, you may find
it easier and cheaper to get a Bluetooth to serial adapter, or a
non-802.11 wireless to serial box. If you need references, please
ask.

>The machine have it's own ip.

Ummmm... not exactly. Machines do not have IP addresses. Each
interfaces will have its own IP addresses. For example, if you have a
machine (computer) with 3 network devices (Wi-Fi, ethernet, and PPP
serial), each interface will have a different IP address.
