New firmware and CPS

Budapest, the capital of Hungary [Pasztilla aka Attila Terb├│cs (Own work CC-BY SA 3.0 source:Wikimedia Commons)]

This week, Motorola introduced system release R2.3B. Included in this release are firmware packages R02.30.31 for the DP/DM4000/2000/3441 series;  R02.30.13 for the SL4000 series and R01.00.30 for the DP/DM1000 series. For this release a new version of CPS (10.7); Radio Management (1.7) and Tuner (10.9) has been introduced.

There are a few enhancements in this release, which include an Input Method Editor support for Hungarian (hence the reason for the picture).

There is also an improvement to the Enhanced Codeplug Password Protection. The Read/Write codeplug password protection option is now being removed in this release as it presented some problems when programming large fleets of radios. The Read Only codeplug password protection remains unaffected. (Note that this may not apply to models sold in the Americas).

The Enhanced Codeplug Password feature in R2.3A prevented the radio password from being retrieved by means of packet sniffing. The entered password is verified by the radio rather than the CPS. This enhancement is also available in R01.12.13 (see below).

Further details can be found in the R2.3B release notes.

For the DP/DM3000 series, firmware R01.12.13 is now available with some minor fixes - details of which can be found in the release notes.

Where can I download the MOTOTRBO CPS?

The Customer Programming Software required to configure a MOTOTRBO radio is only available to Motorola Channel Partners, who in terms of their agreement with Motorola Solutions, have access to Motorola Online. This is the case for all customers in Europe and Africa.

I understand that in the USA and Canada, it is possible for end-customers to gain access to Motorola Online by purchasing a software subscription licence - this is not available in Europe and Africa. I don't know about Latin America or Asia.

End customers in Europe and Africa can obtain the CPS from the same source as their radios. The radio supplier can, as a service, provide periodic updates for purchased CPS via their website or via Motorola Online. If you need to get the CPS and, for whatever reason, are unable to contact the company who supplied you the radios, then please click here.

If you came here via a Google search, I'm sorry to disappoint you, but it is not possible to download the CPS from this site. Please click here to obtain a legal copy.

Viewing the GPS data on a MOTOTRBO radio

MOTOTRBO GPS model radios allow the user to view the GPS receiver data. The information that can be viewed includes:
- Latitude
- Longitude
- Altitude
- Direction
- Velocity
- Horizontal Dilution of Precision (HDOP)**
- Satellites**
- Version

To access this information on the DP4x01 series, press OK to access the menu. Scroll to Utilities and press OK to select. Scroll Radio Info and press OK to select. Then scroll to GPS Info and press OK to select. Once you are in this menu, you will be able to see the items listed above - press OK to view the data.
Note that this menu option will not be available if GPS is disabled in the CPS. In the DP4x01 series, it is possible to turn the GPS on via the menu.

To access this information on a DP3601 series radios, press #123#.

From a technical point of view, the two values of interest are HDOP and number of satellites. These two values are interrelated in that a low number of satellites will provide a higher HDOP.
HDOP is a measurement of GPS receiver accuracy - the closer to 1, the better. generally, anything below 3 will provide a accurate enough fix.

TX Preamble Duration

Setting the TX Preamble Duration to a value greater than zero causes the radio to insert a string of bits in front of a data or control message (e.g. Text Messaging, Location Messaging, Registration, Radio Check, Private Call, etc.). This preamble prolongs the message in order to reduce the chances of the message being missed by a receiving radio. 

This duration may need to be increased if the radios on the system use scan and there are a number of channels in the scan list. This value can be increased in all the transmitting radios if scanning radios are often missing data messages. However, a larger preamble occupies the channel longer. Therefore, increasing the TX Preamble Duration will increase the success rate of data received while other radios are scanning, but will decrease the amount of data that can be transmitted on the channel (channel loading).

For nearly all applications, the default value of 960 ms is sufficient. Further details about TX Preamble Duration and scan can be found in the MOTOTRBO System Planner.
