Motorola maxtrac 800 manual

It appears that once you exceed the maximum number of channels for a radio and try to program them in, the firmware will "wrap" the extra data around to the beginning and start programming from channel You will be able to tell if you have exceeded the maximum number of channels by trying to program in one channel at a time until it "wraps", ie.

Another thing that might happen is that if you exceed the number of channels programmed into the radio, the display will show funny things as you scroll through the channels, it depends on the firmware in the radio.

OK, we have finally figured out most of the information contained in a record in the. By knowing this, we are able to do things like enable scan, signalling, etc. However, even if you enable the options by editing the. Now, on to the structure itself. The highlighted area below indicates an individual record for a particular model Maxtrac.

The Radius is essentially the same, just with different model numbers. The breakdown of the record is as follows:. As can be seen elsewhere on this page, the Model Index is what actually tells the RSS what radio you are working with. It figures out the index from the codeplug in the radio or on file and locates the appropriate record in the.

Once the RSS knows the Model Index, it can read all the specific information on what that radio is capable of by reading the rest of the model information in the. This byte determines what model name ie. All the possible model names are stored at the beginning of the. If you change this byte, the model name displayed will change. For example, this radio has a byte of 0x If you read this radio, it will have a name of Maxtrac If you change the byte to 0x06, the name will change to Maxtrac These bytes are the hex representation of the actual model number of the radio in question.

That's about it. That is why there is no model breakdown chart for them. The only way to actually figure out the options in a particular radio is to read it. This byte determines which bandsplit information record is used for this radio.

The bandsplit table is located just under the model names at the beginning of the. More information on the structure of that table is available elsewhere on this page. Not exactly sure on how this one works. It depends on what the bandsplit of the radio is and the power level high or low. This byte is a hex representation of the number of channels in the radio. It is explained further elsewhere on this page. This byte is a hex representation of the power level of the radio. It is used to display the power level on the Radio Wide screen.

By changing this byte, you will change the power field on the Radio Wide screen. It has no other effect. These two bytes are some of the most important. They determine what options are enabled in the radio and are capable of being modified by the RSS. Now, just because you enable the options, it doesn't mean that your radio will support them, that depends on the firmware in the radio, as well as the codeplug in the radio.

It is generally possible to upgrade the firmware in the radio, and usually will involve blanking, re-initializing, and re-tuning the radio in the process, but it is possible. It also appears that some options need to be turned on in the codeplug of the radio, regardless of whether those bits are enabled in the. The bytes in the radio that seem to affect these options are at offset 0x1FE and 0x1FF in a codeplug archive.

Options are determined by whether a specific bit in the option bytes are turned on or off. Each of the two option bytes can be broken down into an upper nibble, and a lower nibble. When each nibble is converted to binary, you get all the possible option bits that can be changed.

Normally both bits 1 and 2 are always set. To determine what to put in the. In general, if you want to enable scan and signalling if supported by your radio , use the option bytes in this example 0x27, 0x1C.

With version R Depending on what the code is, determines the block of data in the codeplug which is corrupted. PayPal is the only accepted form of payment.
