  • Page 5: Section One : Introduction

    SECTION ONE : INTRODUCTION ! CAUTION ! These Amplifiers operate at high RF power levels, internal supply energy levels and mains supply current levels. They also incorporate devices containing toxic BeO. Installation, operation and maintenance of this unit must therefore, only be carried out by suitably qualified personnel, familiar with and fully utilising the safety procedures such equipment demands.

    The microprocessor on the Main Board provides all control and monitoring of the hardware on the board, including analogue to digital conversion of power supply levels. It also interfaces, via serial data links, with other hardware control microprocessors on the Amplifier Control Board and on the Front Panel module (separate dedicated bus –...

  • Page 7: 12V Supply And Fan Control Board

    1.1.4 : 12V Supply and Fan Control Board This board contains a 20W DC-DC converter, which provides a regulated +12V dc supply from the main 36V (XA150) or 48-50V (XA300) Power Supply. The +12V supply is further processed and regulated to provide +5V and - 12V at point of delivery. The board also provides accurately tapped outputs from the input 36/48V line and output 12V line to feed the A-D converter on the Main Board, thus enabling a display of these voltage levels on the Front Panel or remotely.

  • Page 11: Section Two : Installation

    SECTION TWO : INSTALLATION ! CAUTION ! These Amplifiers operate at high RF power levels, internal supply energy levels and mains supply current levels. They also incorporate devices containing toxic BeO. Before commencing installation, it is recommended that the complete INSTALLATION section is read and understood. The instructions should then be strictly followed, by suitably qualified personnel, otherwise sub- standard or even dangerous operation may result.

  • Page 12: Rack Mounting

    2.1.2 Rack Mounting If the Amplifier is not supplied ready mounted in a 19 inch rack, this will be required to be done at time of installation. The 19 inch rack should ideally be of standard 600mm depth and requires at least 2U for the XA150/300.

  • Page 13: External Conections

    2.2 EXTERNAL CONECTIONS All permanent external connections are made at the rear of the unit in accordance with system requirements. The connections required are made as described in the following sub sections. 2.2.1 Mains Supply Connector This is a standard IEC connector PL02, at the right rear of the unit, intended for connection to a single phase (plus protective earth) supply.

  • Page 14: Tcp/Ip Connector

    2.2.4 TCP/IP Connector This is an RJ45 connector SK03 fitted at the rear of the unit. This enables all the control and monitoring detailed in Section 2.4 to be performed using TCP/IP (Transmission Control/Internet Protocol). This arrangement requires the unit to be assigned a unique Internet Protocol address. When first connected to the network via its RJ-45 connector, the Amplifier’s TCP/IP adapter will attempt to acquire an IP address automatically (it’s quite common to have networks configured to use ‘DHCP’, which provides these addresses on demand).

    The lead terminates in a 25 Way free D plug at the Amplifier end which is wired as follows :- Pins Not Used 1-6 1 -6 Pin 7 Forward Power Low (approx. –2dB rel. set o/p - pulled to ground when good) Pin 8 Forward Power Fail (approx.

  • Page 16: Setting Up Procedures

    2.3 SETTING UP PROCEDURES 2.3.1 Fuses If any problems occur after the Amplifier has been installed and switched on, fuses may need to be checked and possibly replaced. However, a blown or high impedance fuse would generally indicate the presence of a fault, which would need correcting. The type, function and access to fuses is as follows : Type Function...

  • Page 18 9) Slowly increase the source power level until 150W (XA150) or 300W (XA300) is obtained. To ensure complete accuracy, an external calibrated meter should be used to measure this output power. On the XA300 only, increase the input level by a further 1dB (approximately 20%).

  • Page 19: Serial Remote Control And Monitoring

    2.4 SERIAL REMOTE CONTROL AND MONITORING 2.4.1 Introduction Serial control via the rear panel COM PORT connector (section 2.2.6) uses asynchronous data (1 start, 8 data, 1 stop bit, no parity) at 2400, 4800, 9600 or 19200 Baud. Control commands and status monitor requests are detailed in section 2.4.2.

  • Page 20: Reverted Status Monitor Information

    2.4.3 Reverted Status Monitor Information The status of the Amplifier is reverted in response to the ? command (see section 2.4.2). After the third byte is echoed back to the remote control unit, a further fifteen bytes are sent immediately from the Amplifier, with no delays between individual bytes (each 1 start, 8 data, 1stop, no parity).
  • Page 21 The following four tables detail the contents of the various strings of reverted status information. The final column in each defines which ASCII values a particular byte can have. The table above defines the meanings of these values. The first byte in each table is the echo of the third byte sent from the remote control unit.
  • Page 22 Reverted Analogue#2 Data Block (15 extra bytes reverted in response to # ? X sequence) Title Status Possible Values (ASCII) Ana2_Data1 Analogue#2 request byte third byte echo fixed at X Ana2_Data2 High voltage MSB (Volts) Ana2_Data3 High voltage MSB-1 (Volts) Null (blank) Ana2_Data4 High voltage LSB+1 (Volts)

Potentiometer LED Display Red indicates fan off Green indicates fan on SYSTEM LED Display Red indicates one or more system conditions are abnormal. NORMAL Green indicates all significant system conditions are normal.
  • Page 24 3.2 STATUS, PERFORMANCE AND LEVEL MONITORING Once installed as described in Section 2, most operations only involve monitoring Amplifier status, performance and levels etc. Note however, that for output power to be generated, the Amplifier’s rear panel Interlock pins (pins 1 and 2 of PL07) must be short circuited, either directly, or by closing of all connected Interlock circuits (see section 2.2.13).
