All that is required is for the connection of suitable cables. 2.2Power Supply If a power supply other than an appropriate Tait model is used, ensure that it is capable of providing enough current to drive the T800 system and is also free from excessive ripple or noise. The system should be protected by the use of appropriately rated fuses in the power supply. Note:It is particularly important when the prime power source is a battery that fuses be employed in all supply lines. 2.3Reverse Polarity & Overvoltage Protection A crowbar diode is fitted to all T854 transmitters exciters for protection against connec- tion to a power supply of incorrect polarity. It also provides overvoltage protection from voltage transients caused by lightning strikes. Note:A fuse must be fitted in the power supply line for the diode to provide effec- tive protection. M800 SL2FIII Copyright TEL01/03/02 2.4Wiring The D-range input and output connections are shown in Figure 2.1 and Figure 2.2. Ensure that the cables are not subjected to any stresses due to tight bends or incorrect lengths. Make sure the RF coax cable to the N-type connector is free from sharp bends or twists. If access to the rear of the rack frame is restricted, the cable should be long enough to allow the chassis to be fully withdrawn from the guide.

The RF section of the transmitter comprises a fre- quency synthesiser which provides 100mW of frequency modulated RF drive to a two stage, wide band output driver followed by a 25W power supply. A thermal shutdown feature is provided in the T854 in case operating temperatures exceed acceptable levels. The T854 is rated for continuous operation. The T854 is rated for a continuous output power of 25W at +60°C. This is achieved via a high capacity heatsink, electric fan and shroud. The fan draws air across the heatsink to dissipate the heat. The heatsink replaces one of the usual T800 covers. A wide selection of audio characteristics may be obtained from the audio processor. Optional circuit blocks are an audio compressor and a pre-emphasis stage. They can be bypassed or linked to one or both audio inputs, and then back into the remaining audio circuitry in almost any combination. All audio processor options are link selectable. The synthesiser frequency is programmed via the serial communications port. Eight channel select lines are accessible via an optional D-range connector (D-range 2 - T800-03-0000) at the rear of the set. All components except those of the VCO are mounted on a single PCB. This is secured to a die-cast chassis which is divided into compartments to individually shield each sec- tion of circuitry. Access to the PCB is primarily through the top cover of the radio, as all components are mounted on the top side of the PCB. There is provision within the chas- sis to mount small option PCBs. The front panel controls include line sensitivity, microphone socket and carrier switch. This switch turns on the carrier (unmodulated) as an aid to servicing. The T854 is designed to be part of the slimline frame. 1. Although capable of operating over the 400-520MHz frequency range, the T854 and T857 have an 8MHz switching range (see Section 1.2.3 and Section 3.1).

Where applicable, the test methods used to obtain the following performance figures are those described in the EIA and ETS specifications. However, there are several parameters for which performance according to the CEPT specification is given. Refer to Section 1.2.6 for details of test standards.

Thereshould be adequate airflow over the fins at all times. Extra airflow canbe provided by fitting an auxiliary fan kit such as the T800-19-0010(refer to the T800 Ancillary Equipment Service Manual or your nearestTait Dealer or Customer Service Organisation for more details). The T858 and T859 PAs are designedfor use in a standard 483mm rack frameusing Tait M800 SL2 guide rails. Theguide rails are securely mounted to therack frame with front and rear retainingscrews, and the PA is secured into theguide with two (T858) or four (T859)front panel mounting screws. Figure3.1 shows the standard, double widthguide designed for use with the T859,while Figure 3.3 shows how the PA canbe latched in the extended position.For more information on availableguide kits, refer to the T800 AncillaryEquipment Service Manual or yournearest Tait Dealer or Customer ServiceOrganisation. Figure 3.1 T800-45-0001 PA Guide Kit The PA rear panel has three connectors: a BNC for RF input (from an adjacent T857exciter), an N-type for RF output and a D-range for all DC, audio and control connec-tions (refer to Figure 3.2). Figure 3.2 T858/859 Chassis Connectors Figure 3.3 T858/859 PA In Latched Position Note: You will need appropriate extension leads if you wish to carry out anyadjustment procedures with the PA withdrawn from the rack in the latchedposition. Alternatively, disconnect and withdraw the PA and reconnect itbehind the rack. 3.2 Rack Wiring The D-range input and output connections are shown in Figure 3.4. Ensure that thecables are not subjected to any stresses due to tight bends or incorrect lengths.Make sure the RF coax cables to the N-type and BNC connectors are free from sharpbends or twists. If access to the rear of the rack frame is restricted, the cables should belong enough to allow the chassis to be fully withdrawn from the guide.

Caution: Connect the power supply directly to the PA, and not via connector blocks. This will avoid overheating of connector blocks that are not ofthe correct current rating. 3.4 Reverse Polarity & Overvoltage Protection A crowbar diode is fitted to all T858/859 PAs for protection against connection to apower supply of incorrect polarity. It also provides overvoltage protection from voltagetransients caused by lightning strikes.Note: A fuse must be fitted in the power supply line for the diode to provide effec-tive protection.
