Harris mobile programming cables

[GeoFenceFound]

Hey guys I got a friend that went from a portable to a mobile, M7300, and needs a programming cable for it. I would prefer a USB cable that would work since both him and I do not have any computers with serial ports anymore. I have heard that a Serial to USB cable can work at times depending on the brand. I bought one from best buy today that I will try tomorrow with a windows 10 surface pro. If this doesnt work I need to figure out other options. I have not located a usb programming cable online that is made for this radio, all I see are serial cables. I emailed my local radio shop that does harris stuff and havent heard back yet.

suggestions?
thanks!

As long as the serial to usb adapter has the ftdi chipset it should work if the software is windows 10 compatible...

M7300's program with your garden variety 9 pin serial cable. How you connect to your PC is up to you. There is no USB programming cable for M7300. You can get a programming cable that connects to the mic connector on the CH721 if you wanna drop $120, but its still a serial connector.

The one I have uses a a prolific chipset. I will get a FTDI one and try both and report back. Thank you for the heads up!

Programming via the CH721 is also much slower. The Harris sold/recommend Serial/USB adapter is made by SeaLevel Systems.

So a cheap $25 cable from best buy I have worked great!!

This. The SeaLevel adapter just works. Other USB to serial adapters have been more miss than hit.

Plus, you cant do firmware updates from the CH721. only the serial port in the rear.

Concur on what the others are telling you; Harris still seems to love RS232 ports for some reason even though USB-Serial adapters can sometimes be hit or miss. Their newest portable line (XL) uses USB cables, but everything before (XG, M7100, P7100, etc) uses 9-pin serial.

Firmware updates of the XG-series radios are also hit or miss (mostly miss) when using a USB-Serial adapter; I've tried various flavors of them. I keep an older Toshiba laptop with a 9-pin serial port in the office for those times where I need to do a firmware update on an XG-series radio. I've got a Panasonic Toughbook at home which also works well.

If you have to go with a USB-Serial adapter, definitely go with the FTDI chipset.

Do yourself a favor if you have to maintain radios like this; scare up a computer with a comm port for stuff like this. Panasonic CF-30 Toughbooks are an excellent choice; I've seen decent ones on eBay for $200 or less in good condition.

Wise advice. There's a reason that we use Panasonic Toughbooks in the radio shop (currently CF-53s) due to the native serial interface. With that said, I have never had an issue loading code with a SeaLevel systems adapter. In fact, when we are doing mass code updates, we use a SeaLevel systems SeaLink+8 to drive 8 serial programming cables at once.

So if I'm understanding correctly... the Orion/M7100 serial cable will work to program the M7300/XG75M as well?

No, the Orion/M7100 use a specialty cable (DB9 on one end) that plugs into either the 37-pin accessory port on the back, or the 15-pin pigtail lead coming off the 37-pin accessory connector (an option when the radio was purchased).

The M7300/XG75M uses a standard, off-the-shelf 9-pin serial cable (DB9 female on one end, DB9 male on the other end).

Thanks for the clarification.. so just a straight-through serial cable?
