OPERATION Power Jack - Connection point for a nominal 12-volt, negative ground power source. Microphone Jack - Connection point for the microphone and also the RPI programming interface when programming the transceiver. Microphone Push-To-Talk (PTT) Switch - Keys the transmitter. Speaker Jack - Connection point for an external 4.7-ohm, 5-watt speaker. The internal speaker is disabled when a speaker is connected to this jack. Speaker - A speaker is located behind the grille.
PAGE 31
OPERATION Upper Decimal Point - Indicates that the function controlled by the AUX1 switch is enabled. - Indicates that a call has been received on a group programmed for a call indicator (see Section 3.5.3). To turn this indication off, press any key. Lower Decimal Point - Indicates that the function controlled by the AUX2 switch is enabled. - Indicates that the monitor mode is enabled.
PAGE 32
OPERATION (high tier models only). It may also be possible to enable a reference tone or audio for setting the volume level using one of the following methods: • If key press tones have been enabled as described in Section 3.5.17, a short tone can be enabled by rotating the select switch (high tier models) or pressing an option switch. • If a conventional system is selected, take the microphone off-hook to enable the monitor mode. If someone is talking, audio is then heard.
PAGE 33
OPERATION After the highest programmed number is displayed, wrap-around to the lowest programmed number occurs and vice versa. The wrap-around tone sounds when this occurs (if tones are enabled). Programming of the “Select Knob Default” parameter determines if the transceiver reverts to the system or group select mode. For example, if it is programmed for the group select mode, it is in the group select mode when power is turned on and returns to that mode when the programmed delay timer expires.

OPERATION “SQUELCH” on the top line of the display, and the relative squelch level is indicated by a bar graph on the bottom line. mation on LTR features, refer to Section 3.8 and LTR Application Note, Part No. 009-0001-020, rev. 8 or later. 4. To select the current level and exit the mode, press the AUX1/AUX2 (low tier) or Select (high tier) switch again. This also occurs automatically 2 seconds after a change is made or 8 seconds after no activity.
PAGE 35
OPERATION If the transceiver is programmed to not detect an off-hook condition, taking the microphone off-hook does not disable scanning or enable the monitor mode. The option switch or the Transmit Disable On Busy feature must then be used to perform monitoring. 3.4.8 PLACING AND RECEIVING STANDARD (DISPATCH) CALLS • If an out-of-range condition exists, the intercept tone sounds and “OUT-RNGE” is indicated on the lower line of the display (high tier only).
PAGE 36
OPERATION placed in the conventional mode, the procedure used depends on the specific interconnect equipment being used. Select switch to change the bank. The alpha tag of the current bank is displayed on the bottom line. Any programmed system can be assigned to a bank, and the system numbering can be different for each bank. Only the systems in the currently selected bank are selected or scanned, and at least one bank is always programmed.
PAGE 37
OPERATION 3.5.4 COMPANDING or last selected voice group is selected. Refer to Appendix A.4 for more information on operation with a modem. The companding feature is optional with this transceiver. It is a separate module that installs in Option Slot 2 (or 1) on the audio/logic board. Companding improves audio quality by decreasing the amount of noise present in the audio signal. It does this by providing a 2:1 compression of the audio signal on the transmit end and a 1:2 expansion on the receive end.
PAGE 38
OPERATION 3.5.9 HOME SYSTEM/GROUP SELECT shown below. With low tier models, if one of the auxiliary switches is programmed for encryption (see next paragraph), the display decimal point associated with that switch is the encryption indicator. The Home Select feature quickly selects the preprogrammed home system/group. With low tier models, this is done by pressing the AUX1 or AUX2 switch programmed for this feature.
PAGE 39
OPERATION by programming the horn alert default to “ON”. Operation in each mode is then as follows: for .25, .50, .75 or 1.0 second, and the cycles are programmable for 1-8. Horn alert installation is described in Section 2.4. Mode A - If the horn alert is to be always enabled, this mode could be used. Operation in Modes A and B The horn alert is programmed to operate in Mode A or Mode B (descriptions follow).
PAGE 40
OPERATION 3.5.14 PROGRAMMABLE POWER OUTPUT A turn-off delay allows features such as the horn alert and call indicator to remain active for the programmed delay time after the ignition switch is turned off. At the same time, advantages of ignition switch control can be utilized such as preventing battery discharge that may occur if the transceiver is accidentally left on for an extended period. With low tier models, one of two power output levels can be PC programmed for each LTR and conventional system.
PAGE 41
OPERATION occurs, the return time warning tone sounds to indicate that time-out is approaching. If temperature continues to increase at the low power setting to the point where more serious damage could occur (this should seldom happen), the transmitter is disabled, a warning tone sounds, and “NO POWER” is displayed (high tier models only). The transmitter remains disabled until temperature decreases to the first temperature limit. Power output is then produced at the preset low setting.

OPERATION the tones, tri-color indicator, and backlight. Refer to Section 3.5.15 for more information. System/group scanning is turned on and off by the Scan option switch. When system/group scanning is enabled, the green scan indicator is lighted, and when scanning is actually occurring, the “+” indicator is lighted (see following illustration). 3.6.23 SQUELCH ADJUST Refer to Section 3.4.6 for information on setting the conventional mode squelch level. Scan Occurring 3.6.
PAGE 46
OPERATION Other Scan Information With low tier models, if the Scan option switch is disabled, scanning is fixed in the programmed default condition. With high tier models, the following configurations can also be programmed: With all models, calls on the priority and block ID codes are detected regardless of group scan programming. All that is required is that the system with those codes be selected or scanned.
PAGE 47
OPERATION High Tier Models saved and the scan list returns to the same state when power is turned back on. Conversely, if “OFF” is programmed, they are not saved and it reverts to the programmed default status. The system and group scan lists are user programmable using the A/D (add/delete) option switch. If this switch is not programmed or disabled, scan list programming is not available. The displayed system is in the scan list and scanned normally when is displayed.
PAGE 48
OPERATION that a call is received before scanning resumes. This prevents scanning from being delayed for long periods by lengthy calls. This time can be programmed for 0-60 seconds in 1-second steps. If “0” is programmed, there is no time limit and the entire message is always received. If the menu SCN CONT parameter is available, this feature can be turned on and off by the user (see Section 3.6.20). Last Received - The selected system/group changes to the system/group of a call.
PAGE 49
OPERATION with the same system number, system information is loaded only once. Therefore, there is no delay with to change systems which results in very efficient scanning of those positions. The group select and group scan functions are not available with this transceiver.

OPERATION priority calls. The priority order of the decode ID codes is as follows: 1. 2. 3. 4. Transmit Disable On Block IDs Each bank can now be programmed so that transmitting is inhibited while a call is being received on a block ID code. This operation is selected on the Create/Edit Bank screen by programming “Inhibit Transmit During Block Decode = Yes”. The transmitter can be keyed immediately after the call is complete (there is no 5-second delay as with the transmit inhibit feature).
PAGE 51
OPERATION Placing an LTR Telephone Call pressed to talk and released to listen, the same as with a standard calls. 1. Turn transceiver power on and set the volume as described in Sections 3.4.1 and 3.4.2. 6. When the call is finished, press the # key to terminate the call. Three beeps indicate that the call has been terminated. Terminating the call in this manner prevents extra billing that may occur for the time required for the system to automatically detect the end of the call. 2.
PAGE 52
OPERATION 3. Ringing is then heard by the landside caller while the mobile is being rung. random delay minimizes the chance of collisions with other transceivers in queue. 3.8.6 TRANSMIT INHIBIT If an access attempt is unsuccessful, another attempt is made after another random delay. This continues until an attempt is successful. A beep then sounds and the dial tone is heard. The number can then be dialed if desired.
PAGE 53
OPERATION group is selected and a dial tone sounds. The number must then be sent by the user within a few seconds or normal operation resumes. This mode can be canceled at any time by pressing any option switch. system selected, NOT CONV is displayed (high tier only) and monitoring is not selected. If the microphone is taken off-hook with an LTR system selected, scanning halts (unless off-hook detection is disabled) but monitoring is not selected. 3.8.
PAGE 54
OPERATION 3.9.4 TALK-AROUND The Call Guard squelch feature eliminates distracting messages intended for others using the channel. This is done by using a subaudible tone or digital code to control the squelch. This tone or code is unique to a user or a group on that channel. This tone or code is transmitted with the voice signal but is not heard because it is in the subaudible range and is attenuated by a filter.
PAGE 55
OPERATION used. When the push-to-talk switch is released, a turnoff code is transmitted which eliminates the squelch tail similar to the reverse burst. • Although there are thousands of possible code combinations with 23 bits, only 83 are unique with the data scheme used. The number specified when the code is programmed is actually a seed for a special algorithm used to generate the 23-bit data word. The data is transmitted at a rate of 134.4 bits per second.
PAGE 56
OPERATION pressed, program the applicable conventional group for AND EXT = “Yes” (TX CCG category). As in the receive mode, the Call Guard and external decoder functions are “ANDed”. Therefore, if transmit Call Guard squelch is programmed, it is also transmitted. squelch control output from the decoder is the IN2/IN3 wire-outs of the option slots on the audio/logic board. Outputs which may control a decoder or encoder are the OUTPUT A and B wire-outs.
PAGE 57
OPERATION Repeated access attempts are made while the PTT switch is pressed with this tone sounding. Therefore, it is not necessary to release the PTT switch to access the system. Proceed (Clear-To-Talk) Tone - This is a short (700 Hz, 50 ms) tone which sounds after the push-to-talk switch is pressed to indicate when talking can begin (see Section 3.5.13).
PAGE 58
OPERATION release the PTT switch, and you may partially hear this tone. BLK CALL - Indicates that the call is being received on an LTR block ID code (see Section 3.8.3). Proceed Tone - This tone consists of two beeps and it tells the landside caller when to enter the five-digit number specifying the mobile being called. Dialing of this number must be started within 5 seconds of hearing this tone, and a tone-type telephone must be used.
PAGE 59
OPERATION NO TALK - Indicates that talk-around has been disabled on the selected conventional system by programming (see Section 3.9.4). TX INHIB - Indicates that the transmitter has been disabled by the Transmit Inhibit feature (see Section 3.8.6). NOT CONV - Indicates that an attempt was made to enable a conventional mode feature on an LTR system. 3.10.4 MENU MODE MESSAGES (HIGH TIER ONLY) The following messages are displayed in the menu mode that is described starting on page 15.

DATA INTERFACE DESCRIPTION Table A-1 Data Interface Line Electrical Specifications (Continued) Name Output E Output F Option 1 Transmit Origin Description U112-14 Not programmable and always the “Rx Data Call” function and active high (not available with data and low tier models). U112-13 Not programmable and always the “Data CTS” function and active high (not available w/low tier). J301-9 Programmable as either an input or output.

DATA INTERFACE DESCRIPTION EMERGENCY - Asserting this signal causes the radio to act as if the “Emergency” switch has been pressed. BUSY - When transmitting, the asserted condition indicates that an attempt to transmit failed because the channel or system was busy. When receiving, it indicates that the current channel or system/group is busy. EXT SERV REQ - Normally, all input lines are polled on a regular basis (approximately every 40 ms) to detect changes.
PAGE 225
DATA INTERFACE DESCRIPTION RX CALL - The asserted condition indicates that a call is being received (either voice or data). TX FAIL - The asserted condition indicates that an attempted PTT or DATA PTT channel access has failed. Possible reasons for this failure on a trunking system are an out of range or system busy condition. On a conventional channel it usually means the channel is busy. This signal is also asserted when a transmitter time-out occurs or an over voltage condition exists.

DATA INTERFACE DESCRIPTION A.4 DATA MODEM OPERATION 3. If the last user selected system and group are a data group, the radio sounds the error tone and displays “U” (low tier) or “DATA GRP” (mid/high tier). A.4.1 DATA GROUP SUPPORT The 9800-series radio includes support for data groups. A group programmed as a data group has the following properties: A.4.
PAGE 229
DATA INTERFACE DESCRIPTION 2. The modem must assert the DATA PTT line for transmission of any ACKs or NACKs. During this time the radio does not encode any subaudible data. 5. For all subsequent assert to release transitions on the DATA PTT line, the radio receives and decodes subaudible data. 3. The modem must release the DATA PTT line for the reception of any more data. During this time the radio decodes subaudible data. 6. The data session is completed by the release of the DATA ARQ line. 4.

EXTERNAL SERIAL CONTROL PROTOCOL Formatted data string: Command frames are always responded to by an ACK or NAK message from the receiver and they cannot contain a broadcast destination address. 0xba, 0x01, 0x02, 0x37, 0x10, 0x02, 0x33, 0xFF, 0x10, 0x00,0x10, 0x00, 0x10, 0x02, 0x7e Event Frames NOTE: The checksum is 0x10 and it is also followed by an ESC character. Event frames are used to indicate that certain events or conditions have occurred. The subscriber unit is the arbitrator of events.
PAGE 235
EXTERNAL SERIAL CONTROL PROTOCOL There are conditions under which a Command or Event message cannot be properly processed. In these cases, all devices must do one of the following: • If the destination address was broadcast or was not the device’s address, ignore the message. • If the frame is an Information frame, ignore the message. • If the frame is undefined or unsupported and the destination is the subscriber unit, respond with a NAK message containing the proper error code.
