2 INTRODUCTION

AutoHoot
User Manual

Thank you for choosing AutoHoot Mk3.
AutoHoot is an electronic control unit which can be connected to a suitable horn or sounder to produce a sequence of sound signals with reliable timing removing unnecessary human error. Primary designed for the use in starting sailing races it’s basic operation is simple and intuitive. During the starting sequence AutoHoot’s display shows the countdown time to the start. It comes with a number of pre-programed sequences, and it is possible for the user to write and add their own custom sequences.
It has been designed for simple operation when a particular sound signal sequence is required to be emitted. It is not envisaged that the user would switch frequently between the standard sequences, but this is possible to do. AutoHoot is supplied with over 30 standard sequences pre-programmed into the memory. It is also possible for the user to write and add custom sequences using a C-type USB data cable to a PC or tablet/smartphone with a serial terminal program or app.
In addition to providing a preprogrammed start sequence sound signals for recalls, postponements and for finishing boats can be made. AutoHoot is fully programmable so it’s use is not limited to just stating sailing races. It can be used for many other applications from signals for circuit training and other interval training sessions, foghorn signals and even an alarm clock.

User Manual
7.2 Horn / Sounder A 12V horn or sounder needs to be connected to produce a high decibel output. The choice of horn or sounder will depend on the application.
For starting dinghy races on restricted water, the type of low-cost car horn that can be purchased from a local car accessory shop is suitable. For starting large fleet sailing races on open water, a large truck horn or marine horn would be better.
Car & marine horns can require high peak currents so long cable runs should be avoided. For indoor use, a fire alarm type sounder may produce sufficient decibels as a sound signal. The horn is connected via terminals 1 (-ve) and 3 (+ve) on the green connector blocks.
7.3 Power Supply 12V DC power is supplied via terminals 2 (-ve) and 4 (+ve) on the green connector blocks. The power supply needs to be capable of supplying sufficient current to the particular horn/sounder that is connected. Typically, power will be supplied via a 12V car battery or the committee boat’s main battery.
7.4 USB Configuration Cable The AutoHoot may be operated with any of the standard pre-programmed sequences without connection to a PC. If other sequences are required, it is necessary to connect the AutoHoot to a PC/tablet/smart phone using a standard C-type USB cable.
7.5 Installation Cable entry to the AutoHoot enclosure should be via the fitted cable gland. The cable gland is suitable for cable diameters 5 to 13mm. It includes 2 sizes of grommet; select the most appropriate for the cable size used. The cable gland should be tightened to ensure watertight integrity. Cable connection is to rising clamp style terminals. If the wire used is multi-strand, ensure that all strands are inserted in the terminal hole. Please note that interconnection of all components should be completed prior to applying power. When mounting the unit, it is best if the display is viewed from the 6 o’clock direction.
7.6 Additional Note on Wiring the AutoHoot As the cables can carry high currents which could interfere with AutoHoot’s electronics, the cable within the AutoHoot enclosure should not encroach on the area beyond the terminal blocks as in Figure A but should be arranged to be as in Figure B. If the AutoHoot is being used in a hand-held application a cable tie should be put round the cable to provide extra protection from the cable being pulled though the cable gland. Figure C shows the suggested lengths to strip the cable.

8.7 Running a Sequence To start the selected sequence running, rotate the Auto Switch to the ON position. The green LED will turn on:
Auto Switch in ON position
When the sequence has completed, or in the case of a continuously repeating sequence has run sufficient cycles, rotate the Auto Switch to the OFF position. At any stage it is required to abandon the active sequence (e.g. after a sailing race general recall or postponement) the sequence may be terminated by rotating the Auto Switch to OFF position. Note: It is not possible to pause the active sequence; when the Auto Switch is subsequently rotated to the ON position, the sequence will re-start from the beginning. If at any time, an additional sound signal is required (e.g. on a sailing race individual or general recall or when finishing a competitor) pressing the Hoot Button will produce a sound signal for the duration the Hoot Button is held down.
Hoot Button press & hold for additional sound signal
Using the Hoot Button does not interrupt any sequence that is currently running.

9 ADVANCED OPERATION
AutoHoot is supplied pre-programmed with a number of standard sequences but if one of these does not fulfil the requirements of an application, any possible combination of sound signals may be programmed by the user. For this `advanced’ operation, a C-Type USB Cable is required. Power to AutoHoot can be supplied from the computes USB port for programming and setup but to operate the relay and horn the 12v supply is required. If connecting the AutoHoot to a PC serial emulation software is required for example Hyper Terminal, Tera Term or PUTTY to communicate via the PC’s serial COM ports. If connecting to an android phone or tablet, then the app `Serial USB Terminal’ from the Google Play store can be used. Using the USB connection cable enables the following advanced features to be accessed:
· Output list of all programmed sequences · Output details of each programmed sequence · Programme custom sequences · Adjust settings current sequence, time, led brightness · Output a log giving the times of up to the last 300 hoots
9.1 Setting Up Communication between AutoHoot and a PC 1. Unscrew AutoHoot enclosure to access the PCB. 2. Plug a C-type USB cable into AutoHoot. 3. Plug the other end of the USB cable into a USB port on the PC. 4. Start the terminal emulation software. 5. In the terminal emulation programme select the COM port and set it for baud rate 9600, Data 8 bits, parity none, stop bit 1 and flow control hardware. The COM port number will vary depending on what serial devices have been connected to the computer. In this example it just happens to be COM8

1 SEQUENCE = 41 2 NAME = “Demo Start” -> 3 4. Starting from line 3, with one instruction per line, the sequence instructions may then be typed in. Sequences are stored in AutoHoot in terms of actions and delays between actions. A number of parameters, such as the length of the sound signal, may be set.
5. It is recommended that new sequences are drafted in Notepad or other text editor and copied into HyperTerminal using the `Edit’ `Paste to host’ function. More than one line or even the whole sequence may be copied at a time.
6. Whilst in editing mode, typing `?’ after the User Prompt lists all available instructions that may be used to program the AutoHoot:

7. At any time after the User Prompt typing `L’ lists the sequence code currently being edited up to the current line:
-> 6 L 1 SEQUENCE = 41 2 NAME = “Demo Start” 3 HOOT 4 DELAY 01:00.0 5 HOOT -> 6
8. At any time whilst inputting a sequence it is possible to make a change to an earlier instruction line if needed. This is done by pre-fixing the current instruction line with the line number of the line to change. This new line will overwrite the original line of the same number and all subsequent lines entered. Entry of instructions will continue from the edited line.
1 SEQUENCE = 41 2 NAME = “Demo Start” 3 HOOT 4 DELAY 01:00.0 5 HOOT -> 6 3 SET HootLength = 2.5 3 SET HootLength = 2.5 -> 4 HOOT 4 HOOT -> 5
9. When the list of instructions is complete, instruction END must be used to exit the sequence. There is a user prompt `save sequence? Y/N’ before the new sequence is saved.
10. Once the END instruction is input the sequence may not be edited (only deleted in whole).
1 SEQUENCE = 41 2 NAME = “Demo Start” 3 SET HootLength = 2.5 -> 4 HOOT 4 HOOT -> 5 DELAY = 01:00 5 DELAY 01:00.0 -> 6 HOOT 6 HOOT -> 7 END 7 END

9.8 SET Beeps Function A series of warning Beeps may be output by the AutoHoot internal buzzer before the end of a DELAY. The time at which this Beep series starts before the end of the DELAY is defined by SET Beeps (in seconds). The full series of Beeps that may be output is as follows:
Time before end of Warning Beep Signal DELAY 2 min 2 long 1 min 1 long 30 sec 3 short 20 sec 2 short 10 sec 1 short 5 sec 1 short 4 sec 1 short 3 sec 1 short 2 sec 1 short 1 sec 1 short 0 sec Beep equal in duration to HootLength
The proportion of the Beep series that is used will depend on the number of seconds set by SET Beeps. It is also limited by the DELAY. For example, if SET Beeps = 40 and DELAY = 02:00, the Beeps will commence 30 secs to go before end of the delay with 3 short Beeps followed by 2 short at 20 sec to go etc. If the SET Beeps = 40 and DELAY = 00:15, the Beeps will just start with 10 sec to go before the end of the delay. If a warning Beep is required when the sequence is first started or an individual Beep is useful at any stage during the sequence, an additional instruction line of DELAY = 0 may be inserted. Beeps may be switched off by using instruction SET Beeps with no value, i.e. “SET Beeps =”.
