WARNINGS
IMPORTANT NOTE For correct operation, please, read this instruction manual carefully, before operating the equipment.
HIGH VOLTAGES
Radar equipment includes high voltage that can cause injury or loss of life. Danger exists only when the units are opened exposing internal circuits, as when servicing the equipment. You do not face any danger during normal operation. The SRT Adapter Box has been carefully designed to protect personnel from possible injury from high voltages at normal operation.
When inspecting or servicing the equipment it is nevertheless recommended that the Line Switch is left open, as an added protection.
Although every effort has been made to eliminate danger to personnel, no responsibility is accepted for any injury or loss of life suffered in connection with the equipment.
SAFETY SWITCH
The Radar Unit is provided with a safety switch, which disables the Antenna rotation during maintenance and avoids high voltage damage. Always turn the safety switch off, whenever advised in this manual (for instance, before performing any maintenance or installation procedure). Ignoring safety switch operation may produce hazard of electrocution as well as other severe injuries.

Warning Information The following warnings appear in the text of this technical manual, and are repeated here for emphasis:
WARNING USE EXTREME CARE WHEN WORKING ON THE UNIT ONCE THE COVER HAS BEEN OPENED. THE MAGNETRON ASSEMBLY OPERATES AT HIGH VOLTAGES THAT MAY CAUSE FATAL INJURIES
WARNING BEWARE OF HIGH VOLTAGE CAPACITORS. IT IS NECESSARY TO SHORT-CIRCUIT THEIR LEADS BEFORE PERFORMING ANY MAINTENANCE ACTION.
WARNING ON THE ELECTRIC SWITCHBOARD, SET THE POWER BREAKER DEDICATED TO THE PRESENT EQUIPMENT TO “OFF” AND AFFIX A SIGN, READING: “WORK IN PROGRESS - DO NOT SWITCH ON! ”
WARNING USE EXTREME CARE, WHEN WORKING ON THE EQUIPMENT ONCE THE FRONT COVER HAS BEEN OPENED. THE MAGNETRON ASSEMBLY OPERATES AT HIGH VOLTAGES THAT MAY CAUSE FATAL INJURIES!
WARNING SET THE MAIN LINE BREAKER TO OFF BEFORE REPLACING A FUSE. FUSES ARE UNDER VOLTAGE LEVELS WHICH MAY CAUSE FATAL INJURIES!

CHAPTER 1 DESCRIPTION AND MAIN
CHARACTERISTICS 1.1 Introduction
This technical manual provides information, data, and procedures relevant to general description, operation, functional description, scheduled maintenance, troubleshooting, corrective maintenance and replacement parts list of the SRT Adapter Box.
For brevity of description, reference to the equipment in this manual, can also be made by means of the Manufacturer code name:
SRT Adapter Box SRTAB001.
The SRT Adapter Box controls both combined video and standard communication modes.
Combined video is communication in which the video start synchronisation (trigger) antenna signals (Azimuth, heading line) and communication priority (see para.3.2.3) are transmitted on the same RG59 cable (75 ohm).
Standard communication is where the video signal is received on an RG59 coaxial cable (75 ohm), the trigger on another RG59 coaxial cable (75 ohm), and the antenna signals (Azimuth, heading line) are transmitted on the TB1/TB2 terminal strips.

FUNCTIONAL DESCRIPTION
988-10610-001 3-1
CHAPTER 3 FUNCTIONAL DESCRIPTION
3.1 Introduction This chapter provides a functional and detailed description of the main functions and operations performed by the SRT Adapter Box.
3.2 Functional Description The SRT Adapter Box (Chapter 9, Figure 9.1) performs the following functions:
• Ensures adequate power supply level (of 50 V) for the TRTX even with long cable lengths. A 480W AC/DC power supply with universal input from 85 VDC to 250 VDC is located on the right part of the box.
• Safety switch location to interrupt the antenna rotation during maintenance.
• SRT adapter board serving as a decoder to interface with the SRT (TXRX) with a console and standard communication or as a buffer box unit (buffer and signal repeater).
3.2.1 Buffer Box Unit (Figure 3.2)
If used as a Buffer Box Unit, all input signals are buffered while for outputs, more specifically, if the J11 jumper is set to TR-EXT, the external trigger signal is buffered and will exit on the female coax connector J4
In the same way, this configuration also applies to antenna signals (HL,ACP) setting the jumpers J1 and J2 to EXT.
In case of serial transmission, it is necessary to set the jumpers J7 or J8 to receive the TXRX and J3 or J6 in case of reception from the radar console, depending whether these are 232 or 422.
SRT ADAPTER BOX
FUNCTIONAL DESCRIPTION
988-10610-001 3-2
3.2.2 Decoder (Figure 3.2)
In the case of the Decoder, the combined video signal is buffered, amplitude and adjusted, using the Gain Adj (R31) potentiometer, sampled inside the FPGA (U16) .
In this case, the combined video (see parag.3.2.3) from the SRT (TXRX) is decoded into standard communication for the console. In fact, the sole inputs will be the coax video connector on J13 and the TB2 terminal strip (with the serials, power on and safety switch) given that the antenna signals HL and ACP pass through the combined video signal. The FPGA (U16) then samples and quantize the data of the whole signal. The trigger is generated inside the FPGA (U16) and the HL and ACP jumpers need to be set to VCOMB.
Test (only decoder)
In case of malfunction or error on Heading line, azimuth, trigger and serials, it is possible to close the jumper J19. The FPGA will simulate these signals, generating them from the inside.
In case of a positive system response, this means that the error is generated by the TXRX (in case the board is being used as a Decoder).
If the problem persists, contact the nearest service department, refer to the website: pro.simrad-yachting.com and look up support.
N.B.: In case several consoles are connected to one another, it is necessary to place the Adapter box at the end of the chain, since the termination of the video is present on this box by default.

CHAPTER 4 PREVENTIVE MAINTENANCE
4.1 Introduction Normally this Chapter provides the necessary information to execute the preventive maintenance operations which must be carried out in order to ensure the equipment full efficiency. In the case of the SRT Adapter Box, these particular procedures are not scheduled.
What is required from the operator is to inspect the equipment carefully and notice every possible anomaly, such as the integrity of the equipment, the presence of rust, removal of the paintwork, partial loosening of the screws. The operator is also required to clean the equipment and remove any dust, ash and grease, if necessary, using soft cotton and alcohol. Caution must be taken not to use solvent to clean plastic parts.
Take special care to ensure the cooling fans near the vents (10) (Chapter 9, Figure 9.4) are not blocked by dust. Clean them by blowing through with compressed air.

INFO ABOUT LEDS:
1. D9 - TX Green LED
It switches on when the serial data has been received from TXRX/Decoder.
2. D9 - RX Red LED
It switches on when the serial data has been received from the RADAR Console.
