ProMark 3, MobileMapper CE, MobileMapper CX Batteries

The factory batteries are all gone. I checked with the manufacturer in China and the outer mold that was used to build batteries for Thales and Magellan Professional is unusable, thus original equipment batteries are far too expensive to build.


However, there are a number of replacement batteries available on eBay. Search for “ProMark 3 Battery” or “111141 battery” and you should get a fairly large list of them. This [ item ] is available for $18.45 including shipping. They are shipped from a location in the United States.

Batteries are also available with free shipping from Hong Kong [ here ] for a slightly higher price.

I suspect that the cell life is not as good as the original batteries, however what choice do you have?

Windows 8 and USB to Serial Convertors

A couple of months ago I purchased a new laptop computer. It is a screamer. Came with Windows 8 which was updated  automatically to Windows 8.1. I also upgraded from Microsoft Office ’98 to the very latest version.

The first surprise is I love Windows 8.1. I get what it is doing, and I have had no problems with the OS. I like the latest version of Office too.

One of the things that did not work was my old USB to Serial converter. There is something wrong with the USB to Serial converter’s chip-set and the Prolific driver claims it is an unauthorized clone chip (or some such thing.)

I found some work-around’s online, but they look like a pain in the butt. Instead, I purchased a new USB to Serial converter from Amazon. It works PERFECTLY and even works with the Pacific Crest ADL Dealer Program, which I have never been able to get to fully work on any 64-bit machine.

So I can personally recommend this device: [ Tera Grand ] they are $11.25 each delivered with Prime.

I also purchased a [ HDMI to DVI cable ] $3.08 and a [ HDMI to VGA cable ] $4.22. (Again, delivered with Prime.) Both cables work perfectly.

It is an amazing cable word!

WiFi on ProMark 120, 220, 100, 200 and MobileMapper 100, 120

These devices:

ProMark 120, 220 (legacy ProMark 100, 200)

MobileMapper 120 (legacy MobileMapper 100)

can all benefit by connecting to an external source of corrections. Each of these devices have an internal GSM modem, which can be activated by installing a GSM Sim card. An alternative method is to make a Bluetooth connection to a cell phone, however this is extremely difficult.

In the United States, Mexico and Canada many areas are better served by CDMA cellular service (Verizon in the USA.) These devices do not have a CDMA modem. So generally they connect to the internet by WiFi.

But the devices do not have built in WiFi so a SDIO card is used. And the card sticks out the side of the receiver:



You can easily remove the flap:

But this is not weatherproof.

Generally we make it weatherproof with electrical tape:


5CloseUpTapeWhich is not horrible.

If you live and work in an area with EXCELLENT GSM coverage, then you probably don’t care about any of this because you can use the internal GSM radio. However if you plan on using a MiFi (wireless hotspot) which [ I think is the way to go ] then you need to consider this as you think about purchasing a ProMark 220.

In spite of the stupid tape solution, which definitively sucks, the ProMark 220 is still an excellent network rover. It’s performance is nearly equal to the ProMark 800, at a fraction of the price.

ButtonOff Revisted

The previous post Turning Off MM and PM Receivers  generated a firestorm of activity.

Clearly my method for short-cutting the OFF buttons on these devices:

MobileMapper 100, MobileMapper 120

ProMark 100, ProMark 120, ProMark 200, ProMark 220

is popular.

However, it is a lot of work to copy and paste the shortcut. So I am now providing an automated tool to build the shortcut.

This link [ ButtonOff.exe ] will download a short windows program. If your receiver is ActiveSync’ed or connected with Windows Mobile Device Center this program will automatically build the link for you.

Here is what my tool looks like when you run it:





Clicking button 1 will display some basic information about your device (assuming it is connected):

2Finally clicking button 2 will build the ButtonOff link under the Start Menu on your device.

You can now turn the device off (without worrying about the Standby Mode) from the touchscreen:
