Motorola Unit ID Conversions

[mrb188]

I am trying to figure out what to do about unit ID conversions. I used the " (ID # - 800000)16 " formula to get the TG ID since they were 800000 numbers but am not sure how to input individual radio id's. If I use the formula, since the radio ID's are 700000 numbers, obviously I end up with a VERY large negative number. I want the radio ID to show up but not sure how to make this happen.

Thanks

While this topic is not directly related to GRE radios. The shop that programs the radio id usually has the radio set to agency/department, and sometimes radios can be transferred, lost, stolen, and even replaced with a different radio with a new id number all together. The best way I've found is to monitor rid's is with UniTrunker to capture a group of rid's associated with a specific TGID.

Just drop the 7. 712345 would become 12345.

I'm a bit uncertain as to the question, but let's see if this helps any:

1) I assume you are talking about UserID in a Motorola trunked radio system (vs. MDC IDs in a conventional system).

2) For SmartNet/SmartZone radios, the UserID is programmed into the radio as a 4-digit hexadecimal number, in the range 0001h through FFFFh. For Astro 25 trunked systems (a/k/a 9600-baud systems), the User ID is programmed as a 9-digit decimal number in the range 1 - 9999999 (leading zeros not required).

3) If a subscriber radio is programmed for CallerID and the decoded ID does not correspond to an entry in an alias table, most SmartNet/SmartZone subscribers will translate the ID into a decimal number. The decimal equivalents of 0001h - FFFFh are 1 through 65,535. However, these subscriber radios add the decoded decimal value to 700000 in order to pad out the display. Thus, for instance, assume a given user's radio has the UserID of 000Ah. The decimal equivalent is 10. The decoded ID as displayed would be 700010.

4) To further complicate matters, some departments create SmartNet/SmartZone IDs by starting with some decimal value, padding it for some reason (such as to distinguish between a cruiser's fender number in the case of a mobile (MSP, for instance, adds 40,000) or an officer's badge number in the case of a take-home issued portable (MSP adds 50,000) -- and then the resulting decimal value is converted into a hex number for purposes of programming the radio.

For example:

Cruiser fender number = 1203.

Add 40,000 = 41203.

Convert to hex = A0F3h.

5) Working backwards with a decimal decoded SmartNet/SmartZone ID:

Example:

Decoded ID = 741203.

Substract 700,000 = 41203.

Convert to hex = A0F3. This is the UserID programmed in the radio.

Does this help?
