I am running my RFXCOM compatible equipment using a modified RFXtrx433 transceiver that runs directly from a com port, has a metal enclosure, and dedicated filtered power.
It has occurred to me that others might be interested in such a setup, and I will construct a handful more.
If using virtualization (VMWare, etc.), the transceiver can be hung off of a network based serial server. This works really well when using something like vSphere to run HS. I also find pure serial interfaces more stable with HS than introducing USB to the mix.
Note that RFXCOM (meaning the company) will NOT warranty these modified units in any way. However, the chance for damage to the unit is actually during construction, so I see no real risk once they are built. I will warranty any problems for 30 days assuming one doesn't make further modification to the unit.
The transceiver works that same as the normal USB one, except that it has a native serial port. Flashing the firmware, transmitting, and receiving all work that same.
The device is easy to mount with the included metal case (for example in structured wiring cabinets) and the case adds RF shielding (theoretically this should improve receive performance or at the minimum reduces chances for localized electrical interference to the receiver).
Power must be provided for the transceiver, and it can be any voltage between 5 and 30 volts DC. I will supply a 2.1mm power cord pigtail, a 2.1mm power cord connector with screw terminals, and a 2.1mm power to USB connector. With the pigtail or connector with screw terminals you can provide your own power, anything from 5 to 30 volts DC to power the unit. With the USB connector power cord, you can plug the unit into a computer USB port for power only (the data is handled via the rs232 port, the whole point of this custom transceiver). I will also include a 5 volt wall adapter. If you would prefer a 12 volt wall adapter (4 amp), then the price will increase 10 dollars. This option is mainly for those that might have other nearby devices to power with the same power adapter, and would prefer 12 volts.
Contact me via email through the board. Let me know which case you want (see below and post #30).
Included:
-RFXtrx433 in custom metal case (regular case included by default. If you prefer the G106 case, then please specify. See below and post 30 for comparative pictures of the two cases)
-2.1mm power connector with screw terminals and 2.1mm power connector pigtail (for using your own source of DC power)
-5volt wall adapter (upgrade to 12v, 4amp adapter available for 10 dollars extra)
-USB to 2.1mm power connector, in case you want to power it from a USB port (data still goes over native serial port)
-Serial connection cable (DB9 to jack)
-Right angle SMA adapter (for using the stock antenna, with the device sitting flat, or for using to help route the cable off the side of the unit if wall or cabinet mounting)
-1 set of rubber feet (in case you will place it on a shelf or the like)
Bonus while supplies last (I did get a bit more of this stuff, so I still have a few)
-Antenna mounting bracket with SMA connector (for attic, wall, or etc. mounting of an antenna)
-Choice of extra antenna (bigger than stock antenna, see post 30 for various pictures)
-6 foot SMA to SMA jumper
Price:
-275 USD shipped
I have a supply of various SMA coax assemblies and adapters. Please let me know if you also need something in particular (like a 2.1mm connector power splitter for two for four devices, longer coax, or etc).
