MW-520 Product Information

This forum is dedicated to the general computer related issues we all come across on a daily basis, such as e-mail/Internet/Operating System/virus/spyware, etc questions & problems.

As we are primarily a radio discussion group, your mileage may vary on the responses.

MW-520 Product Information

Post by Pj »

This information has been compiled from several sources. Model specific information will be added as it is discovered. As of this writing, the MW-520 series has been discontinued. They can usually be found on eBay time to time. The most common internal option with the radios are the internal data modems. Not all MW-520s had the data modems or the optional GPS. All appear to have the video input.

The 5203 series does support USB booting by a USB floppy drive but seems not boot from a CD based on several tests. The floppy boot support is questionable as several disks will boot, but the machine may stop reading the data after a few minutes. The 5205 has excellent USB floppy and USB CD-ROM support.

A side note, the display unit buttons are designed to work with software written to support them. They are mapped as extended Fxx keys. The red emergency key is mapped differently. If you do have applications that actually support these keys, you need to have a program installed for them to be used. Its called HWDRIVER. This "run once" program installs the proper hardware drivers unqiue to the display and MW-520 to allow the monitor buttons to work. Motorola programs that utilized these buttons are Tx Messenger and Virtural Radio Control Head (vRch). There is a program floating around called "ExtraKeyApp" to allow the buttons to be assigned to other tasks. There are two versions floating around the internet. One is for the MW520, the other is for the MW800. When you run the program it will be obvious if you have the correct one. The file name for both is "extrakey". The MW520 version can be found on the MW520 Yahoo Groups.

The scan/BIOS codes for the display buttons:

Going from left to right they are:

Emergency button: Unknown
Key 1: Windows (124 or 0x7c) / BIOS (100 or 0x64)
Key 2: Windows (125 or 0x7d) / BIOS (101 or 0x65)
Key 3: Windows (126 or 0x7e) / BIOS (102 or 0x66)
Key 4: Windows (127 or 0x7f) / BIOS (102 or 0x66)
Key 5: Windows (128 or 0x80) / BIOS (103 or 0x67)
Key 6: Windows (129 or 0x81) / BIOS (104 or 0x68)

Thanks siigna!

Most 520 displays are 640x480. There are some 800x600 displays out there, but appear to be rare or still in service. Displays came in the following flavors:

VGA Monochrome (amber)
VGA Color
VGA Color Touchscreen
VGA Color Touchscreen 1000NIT (Most common) (FLN2877B)
SVGA Color Touchscreen 350NIT (FLN3020A)
SVGA Color Touchscreen 1200NIT

The high bright/NIT displays can be recongized by the metal "fin" heatsinks on the rear of the displays. These displays also require its own power cable that uses the standard Motorola/spectra style plug.

If there is an IMAGE file on the hard drive, BACK IT UP SOMEWHERE SAFE. There are not too many CD's with factory image files out there. The image file requires Norton Ghost to extract, and that software is not included on the CD's that I have seen.

The touchscreens were made by ELO Touchsystems. If you cannot find the driver packaged with your MW-520, the older generic ELO driver on the ELO site will work with the unit.

The GPS option, if installed, is a Trimble SKII or SK8, and should occupy one of the internal COM ports. If you cannot communicate with the GPS, go to the Trimble website and find TISP Monitor and Trimble Studio. This program will let you configure the GPS. Its a bit tricky, and may require some time to get it to work if its out of wack, but once its setup, you shouldn't have to play with it again. The GPS is installed using a flex cable that is NLA from motorola and mounts top hard drive mount. If you have a GPS equipped MW, you must unscrew the retaining nut on the outside of the unit first or you will not be able to remove the hard drive unit thus preventing you to get to the motherboard.

With the exception of the HWDRIVER for the six display buttons, just about everything else can be downloaded driver wise from the internet once you figure out what hardware is on the main board. Again, the MW520 Yahoo group has most of the Windows 98/2000/XP drivers there.

Windows 95 will work on the F5201 series MW's. Windows 98se, Windows 2000, Windows XP will work on the 5203 and 5205 series MW's. A WORD OF WARNING - You must use the CPU mount (spectra radio mount will also work) if you are going to use Windows XP. As there are no fans on the MW520, Windows XP heats up the unit quite a bit, and if the unit is not elevated to allow the CPU heatsink on the bottom of the unit to have airflow, the CPU WILL fail. You have been warned.

There are two different keyboards that will work with the MW-520. The orginal and most common keyboard features two lights that display over the keyboard. The second, and last release has a slightly smaller form factor, and has red backlit keys. Both connect to the DB connector on the back of the unit. A USB keyboard has also worked with both models running Win98se and better.

The max memory in the 5203 is 128MB. 256MB for the 5205. The 5205 came in both 500MHz and 700MHz and was the last model 520 sold. To my knowledge, there are no "B" models. PC100 is the memory type.

The 5205 out of the box supports the SVGA displays. Recent firmware 5203 also will, older BIOS's on the 5203 will not unless the firmware is bumped up.

For those units that have the data modems, the parameters can only be changed by MW-520 RSS that configures them. WinRSS will program the modem - but is pretty much useless (as in the modem) unless you own your own data network that is supported by the data modem. Pretty much, if you have a supported data network, then you don't need to worry about finding the software. The internal modem supports RD-LAP 9.6, RD-LAP 19.2, MDC4800.

The hard drives are standard 2.5" IDE.

A note on PC Cards: Running anything BUT Windows XP, both cardslots can be used. For whatever reason, under Windows XP, only one card slot seems to work (the bottom one). I have tried all sorts of driver updates, but nothing seems to enable the 2nd slot. You will hear the speaker "clicks" when a card is inserted, but the card will not operate.

When opening the MW-520 CPU, lift the cover from the connector side of the box. If you open from the front (PC Card side), you may damage the hard drive flex. Lift the connect side towards the PC card side to that the cover is vertical, unhook the flex, then it can be completely removed. If you have the internal GPS, you must remove the lock nut on the outside connector to remove caddy.

The 5200/5201 appear to have an internal CF card slot standard on the motherboard. I have heard that some 5203's do as well, but I have never seen one and may have been an early option.

Looking for hardware drivers? Well, there are some files and CD floating around with them, but can be hard to track down. The entire MW520 series appears to have fairly standard hardware thoughout the entire line, with the exception of CPUs. These are the common hardware componets, and can usually be downloaded from the vendor's websites:

Audio: ESS1868
Video: Chips And Technologies / Chips Video Accelerator(64300/10 65535/40/45/48/50/54/55)
Touch screen: ELO Technologies Serial Controllers (IntelliTouch(R) 2310, 2300, AccuTouch(R) 2210)

Most of the rest should be standard windows drivers.

Try the following Yahoo group:

I hate arguing with stupid people. They just bring you down to their level and beat you with experience.
