Introduction To Servicing M2000-00 3.1.5 3.3 Caution: Screw Head Types Pozidriv screws are the preferred standard on all T2000 series equipment. Pozidriv No. 1 and 2 screwdrivers will fit all pozidriv screws used in the T2000: Philips cross-head screwdrivers are not satisfactory for use on these screws. The following diagram identifies the differences between Philips and Pozidriv screwdrivers.

Introduction To Servicing 3.8 M2000-00 The screws used in the control head are No. 4 Plastites, and should not be confused with the M3 screws used elsewhere. When being replaced, the No. 4 Plastite screws must be tightened to a torque of 8in.lb (0.9Nm). With the control head face down, gently remove the PCB (13), along with the keypad (8) and lightspreader (7). Do not disturb the positioning or height of the LEDs, as this is critical for reassembly.

Tuning & Adjustment M2000-00 6 6.1 Tuning & Adjustment This Section details procedures for tuning and adjustment of T2000 series II radios. This is normally only required during product manufacture or after major servicing. The following topics are covered in this Section: Section Title Page 6.1 Tuning Precautions 6.2 6.2 Tuning & Adjustment Points 6.3 6.3 Trunked Radios 6.5 6.4 Transmitter Adjustments 6.
PAGE 44
6.2 Tuning & Adjustment 6.1 Tuning Precautions M2000-00 Refer to Section 4.1 for a list of test equipment required and a suggested test set-up. The following precautions must be observed when carrying out the alignment procedures in this Section. • The microprocessor shield must remain in place throughout the alignment procedure, with its 3 retaining screws torqued down to 8in.lbf (0.9Nm).

Tuning & Adjustment M2000-00 6.3 6.5 Trunked Radios The ‘test’ facility enables T2000 trunked radios to emulate a multichannel radio, using the frequencies reserved for trunking. For a description of how to put the radio in test mode, refer to Section 5.8 “Trunked Radios: Test Mode”. Once the radio is in test mode, tuning and adjustment can be carried out as described in Section 6.4 and Section 6.5.
PAGE 48
6.6 Tuning & Adjustment 6.4.2 TCXO Alignment M2000-00 Close the PTT switch and monitor the transmit frequency with a frequency counter. Adjust RV923 on the TCXO/Tx audio PCB for a channel frequency within ±100Hz at ambient temperature. 6.4.3 Dual Point Modulation Adjustment DC isolate the audio generator from TSP901 using a capacitor (10µF is sufficient). Set the audio generator to 7kHz and inject the audio into the dual point modulation input TSP901 on the TCXO/Tx audio PCB.

Tuning & Adjustment M2000-00 6.4.4 6.7 CTCSS Modulation Adjustment The following instructions apply only to those radios with CTCSS activated and must be carried out before any further modulation adjustment can proceed. Refer to the T2000 Programming Manual for the CTCSS channel programming instructions. The frequency range of the CTCSS tone is 67 to 250.3Hz. Switch to any channel with CTCSS activated. Close the PTT switch.

7.2 PCB Information M2000-00 PCB Identification All PCBs are identified by a unique 10 digit ‘internal part number’ (IPN), e.g. 220-01330-02, which is screen printed onto the PCB (usually the top side). The last 2 digits of this number define the issue status, which starts at 00 and increments through 01, 02, 03, etc. as the PCB is updated. Some issue PCBs never reach full production status, and are therefore not included in this manual.

T2000-A70 Data Modem Kit M2000-00 8.15.1 8.15 T2000-A70 Data Modem Kit The T2000-A70 conventional data modem allows a T2010 or T2015 radio to be used in data applications, and also provides remote channel control via six BCD lines. The command protocol and some test procedures are provided for those wanting to write their own software. The protocol definition is based on the T2000 CCI protocol, with specific extensions to support binary transmission and reception.

T2000-A70 Data Modem Kit M2000-00 8.15.7 Message Format All message packets take the general form: [IDENT][SIZE][PARAMETERS][CHECKSUM] The following table explains each component of the message packet. Message Component Description [IDENT] The message identifier. Identifiers are single ASCII characters (lower-case alphabetical) which categorise the message type. [SIZE] The number of characters which make up the [PARAMETERS] field.

8.15.8 T2000-A70 Data Modem Kit M2000-00 Messages To The RU If the RU receives a command without error, and all parameters are valid, then the command will be executed and an acknowledge will be returned to the DTE. If an error arises, the DTE will be notified with an appropriate response. The following Table describes the commands available to the DTE to control operation of the RU.
PAGE 133
T2000-A70 Data Modem Kit M2000-00 8.15.9 Messages From The RU Messages may be sent to the DTE by the radio as part of a transaction (i.e. in response to a command issued by the DTE) or unsolicited. In the case of solicited commands, the prompt character will be issued after the RU response to terminate the transaction and signify that another may begin.
PAGE 134
8.15.10 T2000-A70 Data Modem Kit M2000-00 Message Command Description Comments [IDENT] Error Solicited response to a transaction error. This advises the DTE that the RU has detected an error condition and cannot proceed with the current transaction. Unsolicited response to a system error. In some cases, an exception condition in the RU may cause an ‘Error’ message to be sent to the DTE independently of any control transactions.

T2000-A70 Data Modem Kit M2000-00 8.15.11 Software Tests The following Table explains the commands that may be sent to test the software. Command Go To Channel Transmit Test Procedure Expected Result 1. Send command “g01206” Radio changes channel to 2, then returns the command prompt. 2. Send command “g0203D4” Radio changes channel to 3, then returns the command prompt. 3. Send command “g03004A2” Radio changes channel to 4, then returns the command prompt. 4.

8.15.12 T2000-A70 Data Modem Kit M2000-00 8.15.6 Circuit Description The T2000-A70 data modem PCB is based on a CML FX469LS 1200/2400 baud FFSK modem IC (IC1) and the baud rate is selectable by PCB links. Receive audio is recovered and fed into IC1 via a buffer amplifier, with filtering (IC5), to attenuate all but the FFSK tones. The signal is demodulated in IC1 and the data fed into the microprocessor, IC2.

Discard the ground lead, and use this screw to secure the remote loom drain wire solder tag to the control head PCB. Note: 3 Ensure that the tag does not make contact with any devices in the control head. Fit the 2 captive M4 nuts (4) into the slots on the remote back panel (2), and mount the remote back panel onto the control head front assembly (1).

Remove the radio dummy front panel (1) by removing the 4 dummy front panel screws (4). Note: In later T2000 radios, the radio dummy front panel is fitted with a remoting connector cover (3). This is unclipped to access the remote loom connector. When fitting a remote loom, it is therefore unnecessary to remove the dummy front panel.

Secure in place using the 4 remote back panel screws, and push the 4 ESD plugs (7) over the screw heads (T2000-A16 only). Refit the remoting connector cover, pushing the slot in the cover onto the remote loom cable.
