TM8200 mobiles MAP27 Implementation Form (Appendix A7) Application Note TN-1075-AN 1 September 2005 This implementation form is based on appendix A7 of the “MAP27 Mobile Access Protocol for MPT 1327 equipment” version 1.5. It describes how the TM8200 implementation complies and varies with that specified by the protocol, and must be read in conjunction with the MAP27 protocol document. Each heading in this document begins with a reference to appendix A7 (for example, A7.1), and other sections of the protocol are referenced throughout this document, usually in parentheses (for example, 5.2.2.4.1). Documentation for integrators, including the MAP27 protocol, is available for download from the Support section of the Tait Electronics Ltd web site. See “Tait Contact Information” on page 11. This form consists of three major parts: 1. General information about the product identification (A7.1.), the physical interface (A7.2.), and the data link layer parameters (A7.3.), and 2. The network layer messages used in the product (A7.4.), and 3. Additional information about network layer messages used in the product (A7.5.). MAP27 is enabled on the radio at programming time, using the Data form > MAP27 tab > MAP27 Enabled field. You cannot enable both MAP27 and the computer controlled data interface (CCDI) at the same time. The radio must be in trunked mode to access MAP27 functionality. A7.1. Product identification Product identification: TM8200 dual-mode (v2.05 or higher) Manufacturer: Tait Electronics Ltd Date: September 2005 Protocol version number: 1.5 A7.2. Physical interface The transmission speed (3.4) is selectable at programming time using the Data form > MAP27 tab > Baud Rate field. 9600 bit/s: ✓ Yes No Page 2 of 11 1200 bit/s: ✓ Yes Others: 19200 bit/s No TN-1075-AN © Tait Electronics Ltd 1 September 2005 There are three ports available for MAP27 asynchronous serial communication with the TM8200. Only one of these ports can be used for MAP27 transmission and reception. The port is selectable at programming time using the Data form > MAP27 tab > MAP27 Port field. The options are: ■ Microphone connector. Select the “Mic” programming option. ■ Auxiliary connector. Select the “Aux” programming option. ■ Internal options connector. Select the “Internal Options” programming option. A7.3. Data link layer The radio supports two modes of data link layer, which are selectable at programming time using the Data form > MAP27 tab > Link Layer Type field. The two modes are: ASCII mode 1. Binary link layer mode. This is the standard mode of operation as prescribed by MAP27. This is enabled by selecting the “Full” programming option. See “Full Mode” on page 5. 2. ASCII link-layer less mode. This is a proprietary mode of operation which is enabled by selecting the “ASCII” programming option. See “ASCII mode” below. In this mode of operation there is no link layer. Messages are sent between the radio and data terminal equipment (DTE) as ASCII representations of the network layer messages. There is no error detection at the link layer level and no acknowledgement of received messages. This allows operation with a terminal program such as HyperTerminal. If the radio receives a network layer message that it cannot process, the radio will reply with a “Protocol Information” message (starting with ASCII value B4hex). When sending messages from the DTE to the radio, the message must be terminated with a carriage return character (ASCII value 0Dhex) or # (ASCII value 23hex). Each of these characters is recognised by the radio as the message terminator and provides the stimulus for the radio to process the received message. Messages sent from the radio to the DTE are terminated with a carriage return character (ASCII value 0Dhex). The maximum message size for ASCII mode (the parameter for the maximum number of octets) is the same as for Full mode. See “Maximum length” on page 5. TN-1075-AN © Tait Electronics Ltd 1 September 2005 Page 3 of 11 The following tables show examples of messages to and from the radio while using ASCII mode. A reference with “A7” refers to a section in this document, and other references refer to the MAP27 protocol document v1.5. Alpha characters may be in upper or lower case.

Additional Network layer Information A mark in a box in front of a row indicates that the radio does not comply with that option or complies in a different way to that specified. A7.5.6. SETUP VOICE / SETUP MODEM (5.2.2.4.1.) As per the MAP27 protocol, except for the proprietary “conference data call request” option. CALL DETAILS: 8 7 6 • 5 4 3 2 1 0 Non-include call 1 Include call 0 0 Individual or group call, called user(s) may reply 1 Group call, called users are not allowed to reply 0 0 Voice call 1 Modem (data) call 0 High priority call 1 Non-priority call 1 0 0 0 Standard call 0 0 1 Conference data call request (proprietary) The “conference data call request” option is used to instruct the radio to not expect acknowledgements to transmitted Tait data protocol (TDP) data packets for a group conference data call. If this is not used for a group conference data call, the call will be cleared prematurely due to lack of receipt of acknowledgement of the transmitted data packet. A7.5.20. OPERATING CONDITION (5.2.2.8.5.) Details of the relationship between field strength value and dBm value are given below. FIELD STRENGTH: 0 0 0 0 0 0 0 0 Field strength not available • 0 0 0 0 0 0 0 1 -254dBm • 1 1 1 1 1 1 1 1 0dBm Others TN-1075-AN © Tait Electronics Ltd 1 September 2005 Range between -253dBm and -1dBm Page 7 of 11 A7.5.24. VOLUME CONTROL (5.2.2.8.10.) The radio supports changing of speech audio volume fully, and indicator level to high or low. Modem audio level is automatically derived in the radio, and manual variation of it via MAP27 is not supported.

DIAGNOSTIC MODE MESSAGES (proprietary) Message types 02, 03, 04 and 05 (hex). These proprietary messages carry data between the radio and DTE when the radio is operating in a diagnostic mode. These modes are intended for factory use only and hence details of the messages are not published. A7.5.26. SITE SELECT MESSAGE (proprietary) The data terminal equipment (DTE) sends this message to the radio to instruct it to perform a site select operation. This causes the radio to select a single channel as a control channel and attempt to acquire it. This form of the message is equivalent to *50 operation from the keypad. When a control channel has been successfully acquired in this way calls may be made as normal. The radio will obey “go to channel” (GTC) commands and participate in traffic channel calls normally, but will always return to the selected control channel at the end of the call. It will not attempt to acquire any other control channel even if service is lost. Page 8 of 11 TN-1075-AN © Tait Electronics Ltd 1 September 2005 If acquisition is unsuccessful, the radio stays on this channel and normal hunting processes are suspended. In this case the radio will indicate “no service”. The message can also be used to instruct the radio to return to normal hunting processes. This also has the effect of clearing out the registration records and forcing the radio to re-hunt. This form of the message is equivalent to #50 operation from the keypad. 8 7 6 5 4 3 2 1 1 1 0 1 1 0 2 R 0 0 0 0 1 0 1 0 CHa 3 CHb Message type R bit 1 = Resume hunting processes. CHa = 2 most-significant bits (MSB) of channel number 8 least-significant bits (LSB) of channel number “R bit” is set to resume the normal hunting processes. In this case the rest of the data is ignored. If “R bit” is clear, the radio will attempt to acquire the channel number contained in CHa and CHb. A7.5.27. TAIT DATA PROTOCOL STATUS MESSAGE (proprietary) The radio sends this message to the data terminal equipment (DTE) to acknowledge that the receiving radio has received the previous Tait data protocol (TDP) packet, or indicate the reason for an unsuccessful attempt. 8 7 6 5 4 3 2 1 1 1 1 * * 0 0 0 1 2 CAUSE Message type Reason for sending this message CAUSE for Message type C1h: 8 7 6 5 4 3 2 1 0 0 0 0 0 0 0 0 Successful transaction CAUSE for Message type D1h: 0 0 0 0 0 0 1 0 Data packet queued CAUSE for Message type E1h: 0 0 0 0 0 0 0 1 TDP format mismatch 0 0 0 0 0 0 1 0 Internal modem failure 0 0 0 0 0 1 0 0 Data channel failure 0 0 0 0 1 0 0 0 Invalid data packet size 0 0 0 1 0 0 0 0 Data channel timeout 0 0 1 0 0 0 0 0 Modem busy 0 1 0 0 0 0 0 0 Transaction aborted 1 0 0 0 0 0 0 0 MAP27 link layer failure TN-1075-AN © Tait Electronics Ltd 1 September 2005 Page 9 of 11 A7.5.28.

USER DATA Message type Free format user data A7.5.30. DIALLED STRING The data terminal equipment (DTE) sends this message to the radio to initiate dialled actions according to MPT 1343. Any function that can be accessed by dialling BCD numeric values (plus hex representations of * and #) using the keypad can be accessed by this message, including call-setups. This differs from the MAP27 protocol, which prescribes that call set-ups shall not be supported by using this message. In this message * is represented by the hex value B, and # is represented by the hex value C. An unused location in the last octet must be padded with the hex value F. For example to dial *49, the dialled string message is B7B49F (letters may be upper or lower case). 1 8 7 6 5 4 3 2 1 1 0 1 1 0 1 1 1 2..
