NOTE 6/28/96: CCS has written requesting that this information be removed as it is old and out of date. I have requested that they send new info. In the meantime, this is presented here for historical purposes only. DIGITAL DATA INTERPRETER TEST SET The Digital Data Interpreter (DDI) decodes digital computer transmissions encoded on an audio signal and interprets the digital data as cellular commands. The input to the DDI is an audio signal like that from a radio. The output from the DDI is plain text over a standard serial data stream at 9600 baud. The DDI will work with a PC, simple dumb terminal, or will communicate directly to some radios. EXAMPLES: CONTROL VOICE 旼컴컴컴컴컴컴컴컴컴컴컴컴컴커 旼컴컴컴컴컴컴컴컴컴컴컴컴컴커 � NAC=15 � � Ring Phone � � 555-4540 (312) Registration� � Stop Ringing � � 555-4540 (312) GoTo 869.880� � Disconnect � � 555-4540 (312) GoTo 869.880� � � � 555-3238 (312) Paging � � Ring Phone � � 555-0186 (312) Paging � � Change Power to .25 W � � 555-8252 (312) Paging � � Change Power to 1.6 W � � 555-0186 (312) GoTo 891.090� � GoTo 890.220 � � 555-0186 (312) GoTo 891.090� � � � � � � 읕컴컴컴컴컴컴컴컴컴컴컴컴컴켸 읕컴컴컴컴컴컴컴컴컴컴컴컴컴켸 The left display shows a control message came in indicating the number of access channels in the system is 15. The GoTo command shows a request for 312-555-4540 to switch to voice channel 869.880. The interaction following on the voice channel, might be like that in the right box. This example shows the system is paging three people. Upon answering a page the respondent would be asked to GoTo a voice channel as is shown with 312-555-0186. The above display has a number of filter options selected to avoid numerous more mundane commands. The right display shows the system requesting a phone to ring, then to stop ringing and to disconnect. Another session follows showing the person in fact answered and is engaged in conversation. During the conversation the system requests the phone to change the power level twice. Eventually the voice channel is changed to 890.220 as the mobile moves into another cell. Once again this display had some filtering options selected to reduce the types of commands displayed. DDI SPECIFICATIONS The DDI requires audio input (3.55mm jack) from a radio or other source of audio containing digital data. The serial output will connect to any standard RS-232 device. The DDI transmits on pin 2 of a 9 pin male jack. The output from the DDI is plain text. The DDI requires 12 VDC at 250ma using a 3.55mm jack (tip +). Many radios however do not provide a good signal from the speaker. For these radios a connection may be required inside the radio. In some cases a part change is also required to slightly increase the NFM bandwidth. As an alternative for better quality and for radios where a part change is not possible CCS offers a small unit to fit into the radio to provide a good signal for the DDI without interfering with the radio. Three wires need to be soldered and the jack on the unit usually can be mounted in the rear of the radio. CCS can provide connection information for many radios. Ask for specific information and prices for your radio. SOFTWARE When the DDI is connected to a PC, standard communications software (like PROCOMM) may be used with the DDI. The DDI comes with software for a PC that may be used to perform advanced tasks. For example, it can be used to wait for only specific commands or phone numbers and take an action on those commands. The PC can be configured to keep a log of specific events. A radio that is controlled over a serial link may be connected to the PC and the software will issue frequency change commands to the radio. A level converter and squelch detect for the ICOM radios is built into the DDI. Only one serial port is required for both the DDI and the ICOM radio. The following is a list of key software features: Two column display to maximize the data displayed. Select desired commands and numbers for display and logging separately. Select criteria for following frequency changes. Scans channels based on user criteria. Automatically tunes and analyses data quality on each control channel. Presents detailed information on cellular system parameters. General purpose scanning module included for non-cellular use. ORDERING INFORMATION DDI PACKAGES The DDI Kit of parts comes with a PCB and all PCB parts. A case, cables and AC adaptor are not included. The kit includes surface mount parts that must be soldered. The DDI subassembly is an assembled PCB. This PCB may be used in a customers custom test equipment. The DDI commercial test equipment set is an assembled DDI installed in a case with an AC adaptor and a 9 pin serial cable for a PC. All three packages include the CCS IBM compatible PC software. CONNECTION KITS Kits are available with instructions and parts for connecting the DDI to some radios. Soldering is required and prices vary from $8 to $18 depending on the radio. A generic kit is available that will work with almost any radio but will require a review of the radio schematic. CCS will quickly respond to your questions about interfacing to the DDI before and after a purchase. Ask for a quote if you would like CCS to modify your radio. RETURN POLICY The assembled DDI may be returned within 14 days for a refund (minus S&H). ======================================================================= ORDER FORM !!!!!!!! DO NOT USE!
