FAQs

Following are the answers to the most frequently asked questions regarding the Automatic Numeric Identification product line.

What Is ANI?

ANI is short for Automatic Numerical Identification. Its basic function is to send a short data burst every time the user pushes the PTT on a two-way radio. The data burst contains a unique number. The number may be from 1 to 8 digits in length. The number tells the receiving end who keyed the radio. ANI's expanded functions allow short messages to be sent and received. Emergency, Man-Down, Select Calls, Status, and Radio Disable are a few of the popular uses. There are countless variations for how to use ANI to improve the operation of a radio system or business. For some specific examples please visit our ANI Applications page.

Are Cimarron's decoders GE-STAR, MDC-1200, FleetSync, and DTMF compatible?

Yes. As shipped, the customer can enable any one of the 4 ANI formats in the decoder.

How do the Dual and Triple Format Options work?

For customers who have a mix of ANI formats in their fleet, the C Plus Decoders are able to decode and display 2 different or 3 different ANI types using the same decoder. There is no need to purchase 2 or 3 separate decoders when 1 will do the job.

In the Dual Format Option, any C Plus Decoder may be ordered to decode any 2 formats in the same unit. With the Triple Format Option, any C Plus Decoder may be ordered to decode any 3 formats in the same unit. Dual and Triple format options are user selectable to any of the ANI formats. You can change the formats at any time.

For example, suppose your radio system has mostly GE-STAR radios but you would like to add a few MDC-1200 radios on the same frequency. You only need a single C Plus decoder to do the job, just order the "Dual Format" option.

Can the C Plus Decoders be upgraded in the field?

Yes. In fact upgrades are really easy because all C Plus units are Flash based. Any software upgrades are performed in minutes by uploading from a PC. Upgrades are normally sent to the customer by email. There is no need to un-wire or disconnect the Decoder. Simply connect a PC to the Decoder's serial port and away you go. The Decoder will be out of service for 3 or 4 minutes at the most.

Do the C Plus decoders acknowledge Emergency?

Yes. As a standard feature C Plus decoders will acknowledge Emergency and ManDown messages. The acknowledgement will occur in the same format it was received in.

What kind of warranty do you offer on your ANI products?

All of the ANI products are guaranteed to be free from defects in material and workmanship for a period of three years from date of shipment.

Do you provide training?

Training is available on a "as needed" basis. Our technical support is free and available M-F 7:30am to 4:30pm PST to answer and assist you with your questions.

Will you install the encoders for me?

Yes. We can install our encoders in your radio. However if you plan to purchase our encoders on a regular basis then you may want to purchase the QPF-2 Windows based PC-programmer to program them yourself. Please call the Sales Department for turnkey installation pricing.

Will your encoders fit in any radio?

Our encoders fit in most any radio. We keep installation notes for many radio models. Contact our technical help department to see if we carry your specific model. If we don't have instructions for your radio, we recommend that you send in your radio and we will do a model install.
