Introduction
The Pyramid Communications Model 2012 is a microprocessor controlled status reporter capable of signaling the dispatcher with 9 one-key status messages plus request for voice communications. By pressing one of the 9 status keys on the front panel, the vehicle number, console routing information, and new status are automatically sent using high speed MPT-1317 data protocol. When the base equipment responds, the mobile unit will indicate positive acknowledgment by updating the display to the current status request. The Model 2012 will automatically re-send its message if the acknowledgment is not received within 6 seconds. If the mobile is out of range, the 2012 will queue the status calls and append a time stamp to each message. When the mobile is again within range of the base, the queued calls will be sent with the actual time the driver pressed the button.
The 2012 is fully compatible with the Speedcalll 912C format. The 2012 easily integrates into existing DTMF systems and provides expanded capabilities within those systems, such as data messaging, emergency function and time stamping. The 2012 also provides a logical upgrade path to high speed MPT-13177 MSK signaling at 1200/2400 baud without hardware change outs by merely reprogramming the unit using any PC. The MPT-1317 protocol provides expanded capabilities such as GPS Automatic Vehicle Location, credit card readers, in-vehicle printer, expanded display & keyboard operation, vehicle monitoring and general purpose I/O via a high speed data bus.
If the vehicle drives out of range, any status requests by the driver will be queued and a time stamp appended to the message. When the vehicle is again within range, each queued message will be sent in order, along with the time stamp information. The dispatcher will receive each message along with the time the driver actually pressed the status key.
The 2012 is capable of receiving and storing up to 16 alpha messages from the dispatcher in both the MPT-1317 and DTMF modes. Each alpha message is up to 16 characters and includes the date and time sent. All messages are stored in non-volatile EPROM with 100 year data retention.
When the model 2012 is connected to a trunking radio and a status key is pressed, the unit will key the radio for 200mS; it then monitors the radio's transmitter for an on-air transmit at all (system not busy), it will retry every 4 seconds until successful or time out (60 Sec). When it detects that the radio is transmitting, it will continue to monitor the on-air line until the transmitter remains keyed for at least 400 mS to ensure that the radio is not handshaking or retrying. After successful acquisition of a voice channel, it will send its status request ensuring the message is received by the base.
The 2012 is PC programmable for all operating parameters including status tags using the FY-1 programming cable. Parameters include: Signaling mode (MSK/DTMF), 1200/2400 baud, ANI on PTT, sequential status reporting, PTT delay, number of retries, and I/O polarities.
The model 2012 works in conjunction with the model 2016D intelligent modem that connects between a PC or mainframe/mini computer to provide a complete dispatch system. The 2016D will also interface with third party vehicle tracking software for GPS and Automatic Vehicle Location.
The high speed RS-485 data bus provides expanded capabilities such as credit card readers, thermal printers, and vehicle monitoring. The data bus can address up to 256 peripherals and provides seamless upgrade path to future options without hardware change outs.
