Helios FM 350 W/750 W/1000 W/1500 W/2000 W, user manual– 10/2013
2. DESCRIPTION
2.1.
General description
Combining the very latest technologies with our proven RF experience, our 350 W, 750 W, 1000 W, 1500 W
and 2000 W transmitters have been designed to offer an innovative and highly reliable solution.
Among the first FM transmitters based on 6th Generation MOSFET, these transmitters are not only more
robust, they also deliver efficiency of up to 74%. Top signal quality and performance are achieved thanks to
the “FM Band Direct to Frequency” digital modulator which is at the heart of this range.
The manufacturing quality and the simplicity of use make these truly powerful transmitters to broadcast
analog FM programs.
The Helios FM 350 W, the Helios FM 750 W, the Helios FM 1000 W, the Helios FM 1500 W and the Helios
FM 2000 W are fully protected against overheating, VSWR and lightning.
They also offers a number of built in functions that can eliminate the additional cost and space requirements
of external equipment.
Fully featured for local maintenance and configuration, they also allow full remote control by Web server,
SNMP, RS232 or GPIOs*.
* Options available with the current version are:
Basic RDS: the internal RDS encoder makes it possible to manage basic RDS parameters (PI, PS,
TP, TA, PTY, MS, DI, radiotext, PTYN, group sequence, AF, 1 PSN, 2 DSN, dynamic scrolling PS)
Audio backup: an audio file stored on a µSD card can be played in case of loss of audio.
GPIO: this additional board allows remote control and management of your transmitter.
TCP/IP: this additional board allows remote configuration via a web site and SNMP management
Please refer to Appendix A for more information on option management.
Project co-financed by the European Union, involved in the Aquitaine Area,
through the European Funds for local development.

3U Rack
The choice of stainless steel as material guarantees against corrosion. The rack structure and the structure
of the monoblock front panel reinforce the device. The rectangular outline of the front panel has an LCD
display. The transport handles are mechanically interchangeable and can be removed. The cover is fixed by
a set of M3 POZIDRIV screws and can be easily removed. The user has access to every module to set the
parameters of the device.
2.4.
Protecting the transmitter
To ensure the transmitter will work with no risk of damage, a series of protections has been set.
2.4.1.
Surge Protector
An optional surge protector module can be added to the chassis. The goal of this module is to limit the surge
caused by lightning. It works after the main protector usually located in the electrical board and before the
power supply protector, thus offering an optimal level of protection. The protector principle is to capture the
surge and divert it to the ground so as to protect the transmitter and its power supplies.
The surge protector used by Ecreso includes multi-MOV technology and a gas discharge tube (GDT) giving
a very high protection and very low parasitic capacitance and leakage currents.
Please refer to Appendix B ‘Maintenance’ for the procedure to replace the surge protection module.

Helios FM 350 W/750 W/1000 W/1500 W/2000 W, user manual– 10/2013
2.4.2.
Protection against VSWR
Several systems coexist to offer the optimal protection against VSWR:
Hardware protection:
In case of open circuit or short-circuit, the RF is cut. When the situation returns to normal, it is
automatically reset. The protection is triggered in case of an overshoot of the reflected power over:
Transmitter power
20 W
100 W
350 W
750 W
1000 W
1500 W
2000 W
Threshold
3W
10 W
35 W
45 W
52 W
90 W
90 W
Software protection:
The software protection prevents the transmitter to reach a given reflected power value by blocking
the control or lowering the power.
Transmitter power
20 W
100 W
350 W
750 W
1000 W
1500 W
2000 W
Threshold
2W
8W
30 W
40 W
45 W
80 W
80 W
Software settings for the reflected power security management (see VSWR Trip, section 5.2).
2.4.3.
Protection against high temperature
The Power Supply module includes its own protector against high temperature: the protector cuts off the
power supply output voltage if the temperature is abnormally high. When the situation returns to normal, it is
automatically reset. The temperature threshold value varies depending on the PSU.
The ambient temperature and the radiator temperature are monitored.
The max ambient temperature is set by software (see menu Temp/Fan, section 6.3.18 or serial
command CONF.AMB.MAX, section 7.2.4), default value is 50°C. In case of overshoot, a Warning
alarm is triggered (Alarm Amb).
The max radiator temperature is set by serial command (see serial command CONF.HEAT.MAX,
section 7.2.4), default value is 65°C for transmitters from 350 to 1000 W, 70°C for 1500 W
transmitters and 80°C for 2000 W transmitters. In case of overshoot, a Warning alarm is triggered
(Alarm Heat). This value cannot be set for Helios FM 20/100 W.
The max internal temperature is set at 70°C for transmitters from 20 to 1000 W, 70°C for 1500 W
transmitters and 80°C for 2000 W transmitters. If the temperature exceeds 70°C, the RF is cut off
and a fault alarm is triggered (Alarm Temp).
2.4.4.
Protections incorporated into the PSU
All Helios FM and Goliath FM module from 350 to 2000 W have an auxiliary power block and a power block,
each having its own protections:
Against overloads: protects by limiting the current. For auxiliary power supplies, it is a protection
against shorts circuits.
Against overvoltage.
Against high temperatures (see previous section).
The main power supply voltage and the auxiliary power supply voltage are monitored as follows:
Main power supply:
if the difference between the measured voltage and the expected voltage is greater than 10%, a
Warning alarm is triggered (Alarm Volt1). Expected voltage is automatically computed.

Helios FM 350 W/750 W/1000 W/1500 W/2000 W, user manual– 10/2013
Auxiliary power supply:
Voltage should be either 5, 12 or -12 V. if the difference between the measured voltage and the
nominal voltage is greater than 10%, a Warning alarm is triggered (Alarm Volt Aux).

For both power supplies, we are monitoring the output voltage (DC); the input is not monitored.
The current is also measured and monitored. The threshold varies depending of the power of the Helios FM:
2 A for the Helios FM 20 W, 8.5 A for the Helios FM 100 W, 20 A for the Helios FM 350 W, 23 A for the
Helios FM 750 W, 29 A for the Helios FM 1000 W, 26 A per amplifier pallet for the Helios FM 1500 W, 31 A
per amplifier pallet for the Helios FM 2000 W. In case of overshoot, a Warning alarm is triggered (Alarm Cur)
and the nominal power is reduced.

5. MAIN PARAMETERS DESCRIPTION
5.1.
Overview
Four interfaces are available to set the transmitter:
The front panel menus for local configuration – see section 6
The serial/Telnet commands for local or remote configuration – see section 7
The Engi PC application for local or remote configuration – see section 8
The embedded web site for remote configuration – see section 9
In all cases, the parameters are the same and they are described below.

5.2.
Remote configuration can only be done if the transmitter is fitted with a TCP/IP board.
TX/RF parameters
These parameters are available as:
Front panel *

* Parameters followed by a star (*) are not available on the front panel.
3 DB (TX.3DB)
With this parameter, set the triggering threshold for the 3 dB alarm. Default value is half the transmitter’s
power (also when in auto mode).
From 0 to 9999 dB (depending on the transmitter’s power)
MAX VSWR (TX.VSWR.MAX)
With this parameter, set the triggering threshold for the VSWR alarm.
From 0 to 99.9
INTERNAL REFLECTED LIMIT (STAT.PREFMAX) *
This parameter indicates whether the reflected power went over the maximum limit. Depending on the
configuration of the CONF.VSWR_TRIG command, it may trigger a VSWR fault.
Off/On
VSWR TRIP (TX.VSWRTRIP)
With this parameter, enable or disable the reflected power safety. In case the VSWR is too high (reflected
power greater than the maximum threshold), RF is shut off and automatically starts again. If the fault is still
present, the cut/restart process is repeated 3 times. If the 3rd time, it is still present, the transmitter is cut for
good.
Off/On

Input switch parameters
These parameters are available as:

Front panel
INPUT SWITCH menu

Embedded web site
Transmitter/Input Select pages
see section 9.4.4
Serial commands and the web site are managed differently: the PRIO parameter for each input sets the
selection order for the various audio sources.
MODE
With this parameter, choose whether audio source selection is done manually or automatically. In manual
mode, the user selected audio source is used regardless of the state of the audio source. In auto mode, the
effective audio source depends directly on the switching configuration and on the channels selected as Main
or as Backup (1, 2 or 3).
MANU or AUTO
MAIN
With this parameter, select the main audio source.
LINE1, LINE2, MPX1, MPX2, PLAYER or GENE
BACKUP 1 / BACKUP 2 / BACKUP 3
With this parameters, select the audio sources which the transmitter will switch to in case of issue.
LINE1, LINE2, MPX1, MPX2, PLAYER or GENE
LINE 1 or 2 / MPX / PLAYER parameters
These parameters are specifically available as INPUT.LINE1.SW / INPUT.LINE2.SW / INPUT.MPX.SW /
INPUT.PLAYER.SW serial commands (see section 7.2.5).
THRESHOLD (INPUT.xx.SW.THRESH) – read/write
With this parameter, set the silence threshold level on the selected channel. In dBr when units are in relative
mode; in dBFS or dBu when units are in absolute mode (see definition of modes section 5.14).
From -90 to 0 dBr
SILENCE (INPUT.xx.SW.SILENCE) – read/write
With this parameter, select the channel (L / R / L or R / L and R) on which silence detection must be
performed (not available on the MPX sub-menus).
L, R, ANY or BOTH

DELAY (INPUT.xx.SW.DELAY) – read/write
With this parameters, set the switching delay in seconds when audio loss occurs.
From 1 to 120 s
BACK DELAY (INPUT.xx.SW.BACKDELAY) – read/write
With this parameters, set the delay before returning to the highest priority channel, in seconds.
From 0 to 30 s

PRESENCE (INPUT.LINE1.PRESENCE) – read only
This parameter indicates the presence of audio signal at the input: none, left, right or L&R.
NONE, L, R, L+R
LEVEL (INPUT.LINE1.LEVEL) – read/write
This parameter is the max audio peak in dBu that can come from the transmitter on the LINE1 input. For
example, if the audio peak from the source is +6 dBu, this parameter must be set to +6 dBu for optimal
operation. If you do not know the audio source level, you may use an audio analyzer or display first level
measurements on the front panel to read the LINE1 LEVEL. Be aware that if the level is poorly set the
deviation may become too low or too high. This level is also called nominal level, i.e. the level producing the
deviation as set in the Modulation menu.
From -18 dBu to +18 dBu
DRIVE (INPUT.LINE1.DRIVE) – read/write
With this parameter, you can slightly compensate the input audio level. It directly affects the final deviation. A
negative value decreases the deviation; a positive value can increase the deviation and/or cause the MPX
hard clipper to be used (if enabled) which in turn may lead to audio distortion. We recommend you leave it at
0 dB.
From -6 dB to +6 dB
RIGHT TRIM (INPUT.LINE1.TRIM) – read/write
With this parameter, you can correct the balance between the Left and Right channels. However, it is better
to look for and correct the cause of a lack of balance (before the transmitter) rather than correcting it at this
stage. A positive value increases the Right channel; a negative value decreases the Right channel level. It is
best to leave it at 0 dB.
From -3 dB to +3 dB

Helios FM 350 W/750 W/1000 W/1500 W/2000 W, user manual– 10/2013
FILTER (INPUT.LINE1.FLT) – read/write
This parameter is crucial: it set the low-pass filter applied on the audio input. The FM bandwidth is limited to
15 kHz, so the filter must be set to 15 kHz for the FM. Digital technology and the quality of the internal
stereo encoder make it possible to set the filter at 16 or 17 kHz while maintaining an acceptable pilot
protection. Select 0 kHz to disable the filter: this solution can be used in mono operation (in stereo operation,
the incidence on the MPX signal and its sub-carrier would be too great) or when a 15 kHz filter is already
used upstream as with an FM processor for instance. In this specific situation, you may also use 2 filters, the
standard 15 kHz standard filter with the external processor, plus the 16 kHz transmitter filter. The listeners
will hear the processor’s filter; the internal filter will take the relay in case of issue with the processor.
0, 15, 16 or 17 kHz
PREACC (INPUT.LINE1.PREAC) – read/write
With this parameter, set the pre-emphasis. Select 0 µs is the audio signal is pre-emphasized before getting
to the transmitter. Otherwise, select according to the country: 50 µs in Europe, 75 µs in the USA.
0, 50 or 75 µs

They are identical to LINE1 parameters, except for the level.
LEVEL (INPUT.LINE2.LEVEL) – read/write
This parameter is the max audio peak in dBu that can come from the transmitter on the LINE2 input. For
example, if the audio peak from the source is -4 dBFS, this parameter must be set to -4 dBFS for optimal
operation. If you do not know the audio source level, you may use an audio analyzer or display first level
measurements on the front panel to read the LINE2 LEVEL. Be aware that if the level is poorly set the
deviation may become too low or too high. This level is also called nominal level, i.e. the level producing the
deviation as set in the Modulation menu.
From -20 dBFS to 0 dBFS

This parameter indicates the current value of the transmitted signal’s excursion in kHz.
From -150 to +150 kHz
DEV MPX (CONF.DEV.MPX) – read/write
With this parameter, set the maximum MPX deviation in kHz generated when the audio source is at the
nominal level (the nominal level is set with the LEVEL parameter of the menus: LINE1, LINE2, MPX1 or
MPX2). It is often set at 75 kHz but this value may vary according to the country and relevant regulatory
authorities. To ensure the sub-carrier levels remain stable, this parameter directly changes the audio
deviation.
From 0 to 150.00 kHz
DEV AUDIO (CONF.DEV.AUDIO) – read/write
With this parameter, set the maximum audio deviation in kHz generated when the audio source is at the
nominal level (the nominal level is set with the LEVEL parameter of the menus: LINE1, LINE2, MPX1 or
MPX2). The audio deviation is set automatically when the MPX deviation parameter is set; however, it is
possible to set the audio deviation rather than the MPX deviation. Increasing or decreasing the audio
deviation affects the total deviation and thus automatically adjusts the MPX deviation. Make sure to avoid
overmodulation.
From 0 to 150.00 kHz
DEV PILOT (CONF.DEV.PILOT) – read/write
With this parameter, set the 19 kHz pilot deviation. For countries modulating at 75 kHz, the pilot deviation
should be 10% of the total deviation, i.e. 7.5 kHz without RDS or 7.1 kHz if RDS is used.

Interaction between the various components according to the input type:
In all cases described below, the transmitter configuration is as follows:
Audio = 67.5 kHz
Pilot = 7.5 kHz
RDS = 4.0 kHz.
In the case of audio inputs (analog or AES), the set MPX represents the total of audio, pilot and RDS. If the
RDS is disabled, the audio is automatically adjusted with +4 kHz.
Ex 1: set
MPX = 75 kHz
Pilot = 7.5 kHz
RDS = 4.0 kHz.
If the RDS is enabled:
Audio = 63.5 kHz
Pilot = 7.5 kHz
RDS = 4.0 kHz
If the RDS is disabled:
Audio = 63.5 + 4 = 67.5 kHz
Pilot = 7.5 kHz
In the case of MPX inputs, if the RDS is disabled, the audio cannot be adjusted.
Ex 2: inject stereo MPX + RDS with:
Audio = 63.5 kHz
Pilot = 7.5 kHz
RDS = 4.0 kHz.
If the RDS is disabled:
Audio = 63.5 kHz
Pilot = 7.5 kHz
RDS on the MPX input:
Audio = 63.5 kHz
Pilot = 7.5 kHz
RDS = 4.0 kHz
With internal RDS:
Audio = 63.5 kHz
Pilot = 7.5 kHz
RDS = 4.0 kHz
Ex 3: inject stereo MPX with:
Audio = 67.5 kHz
Pilot = 7.5 kHz
If the RDS is disabled:
Audio = 67.5 kHz
Pilot = 7.5 kHz
With internal RDS:
Audio = 67.5 kHz
Pilot = 7.5 kHz
RDS = 4.0 kHz
!
The total modulation 67,5+7,5+4,0 = 79 kHz is too high!

Without the FM Limiter option, the CLIP parameter is the only available parameter.
CLIP (CONF.DEV.CLIP) – read/write
With this parameter, set the MPX hard clipper to prevent any possibility of overmodulation on the modulator
itself. This process is carried out digitally right before the RF generation, and is therefore enabled on all the
inputs. If the deviation is greater than the configured value (in kHz), the MPX hard clipper is automatically
enabled. Unlike FM limiters/clippers used in audio processing, this clipper cannot be used continuously for it
generates a noticeable audio distortion. It is therefore best to set it at 0, or at the maximum authorized
deviation, plus a few kHz to ensure additional security with the audio processor.
From 0 to 200 kHz

Helios FM 350 W/750 W/1000 W/1500 W/2000 W, user manual– 10/2013
The FM Limiter option includes 3 processing stages:
AGC: The Automatic Gain Control purpose is to compensate level variations applied to the
selected audio input. The algorithm is wide-band for maximum audio fidelity and gated to avoid
noise and unwanted level corrections.
FM LIMITER: The FM Limiter prevents from over-modulation by limiting the audio peaks.
MPX POWER LIMITER: The MPX Power Limiter is based on to the ITU-R 412 standard applied
on some FM markets.
CLIP STATE (CONF.STATE.CLIP) – read/write
This parameter enables or disables the clipper. Default: off.
Off/On
AGC STATE (CONF.AGC.STATE) – read/write
This parameter enables or disables the Automatic Gain Control processing stage. Default: off.
Off/On
AGC DRIVE (CONF.AGC.DRIVE) – read/write
With this parameter, load more or less the AGC input. At 0 dB gain reduction will be applied when the
transmitter is fed by an audio level higher than the input level setting. Increasing the drive will add gain
reductions, while low audio levels will be increased (more processed). Default value: +4 dB.
From 0 to 12 dBu
AGC ATTACK (CONF.AGC.ATT) – read/write
With this parameter, tune in dB/s the AGC reactivity speed to a volume increase. A high setting is
recommended to protect the FM limiter stage against high audio levels and possible audio distortions.
Default value: 8641dB/s
From 0.1 to 10 000 dB/s
AGC RELEASE (CONF.AGC.REL) – read/write
With this parameter, tune in dB/s the AGC correction speed to a volume decrease. A low setting is
recommended to slowly increase the gain in case of low audio level and maintain maximum audio fidelity.
Set this parameter to 1dB/s or lower for more transparency; 2 or 3 dB/s will give a slightly more processed
result. Default value: 1 dB/s
From 0 to 6 dB/s
AGC GATE THRESHOLD (CONF.AGC.THR) – read/write
This threshold will freeze the AGC operation when the audio level is below the user-set limit. This function
limits floor noise and prevents unwanted AGC processing on the audio. Default value: -20 dB
From -100 to 0 dB
LIMITER STATE (CONF.STATE.LIMIT) – read/write
This parameter enables or disables the FM Limiter stage. Default: off.

7. SERIAL & TELNET COMMANDS
7.1.
Working principle
Helios FM and Goliath FM have a serial interface. The physical connection is done using the SUB-D9
(SERIAL MONITOR) on the front panel. A common computer with an RS 232 interface (example: PC+
Windows + Hyper-Terminal) is all you need to send commands. The dialog is in text mode (ASCII) and no
specific software is required.
Like all serial PC connected equipment, a good cable and correct communication settings are essential to
ensure good communication. The cable must be a straight cable (not crossover), with a female plug to
connect to the PC, and male plug to connect to the unit.
To avoid problems during connection, set the same communication speed and identical settings for both
devices. See figure ‘Port parameters”.
-> 9600
bits per second
-> 8
data bits
-> No
Parity
-> 1
Stop bit
-> No
Handshaking
Commands may also be used in Telnet when the transmitter is fitted with an IP interface.
The commands make it possible to read the functional parameters (R) or even to edit some of them (W).
To retrieve the value of a functional parameter, simply enter the command name and press the <Enter> key.
Example:
To display the status of the 3 dB alarm, type:
ALARM.3DB
The answer, ON or OFF will indicate the 3 dB alarm is on or not.
To set a parameter, type the command name, the equal sign, the new value and press the <Enter> key.
Example:
To set the transmitter working mode (local or remote), type:
CONF.MODE=LOCAL
The answer: LOCAL will indicate the command has been implemented. In case it has not, the message
ERROR CMD will appear.
Protection with a password:
By default, there is no protection to send commands.
This can be secured with the command:
SYS.PASSWORD = my_password, where my_password is the password you chose

Helios FM 350 W/750 W/1000 W/1500 W/2000 W, user manual– 10/2013
To connect without a password, enter:
LOGIN
And if a password has been set:
LOGIN = my_password
For Telnet connections, use the embedded website identifiers (see section 9.7.7), IP_user and
my_IP_password in the following exemple:
LOGIN USER=IP_user
LOGIN PASSWORD= my_IP_password
The password set the the SYS.PASSWORD command is not used with remote connections.
To logout, use the LOGOUT command or close the terminal window. When disconnecting from a specific
port (local or remote), all ports are disconnected.

If several users are connected at once, they all can send commands and change parameters. Le last
edit will always be taken into account.

Advanced measurements
Overview
Four graphs are available on this page:
RF spectrum
MPX output
Current input spectrum
Audio level
On each curve, the button
displays the abscissa and ordinate of a
specific point. Click and drag the abscissa’s label to view other points on the
curve.
Curves are displayed in dBr; the reference takes into account the drive and the trim.
For instance, if the actual input level is 12 dBu and the set input level is 12 dBu, the drive is set to -1 dB and
the trim is set to -0.1 dB, the left level will be displayed at +1 dBr and the right at +1.1 dBr.
The RF Spectrum page displays the same curve as on the overview page but on a larger scale.

Date / Time
A couple of Helios FM internal components are fitted with a clock. This page allows you to make sure they
are synchronized. The IP board clock can be set on this page: it can manage time zones and will be used as
reference for the system clock which cannot manage time zone and which is used for RDS.
 Set system time zone:
The user selects the geographical zone from the list. Important to have this set correctly when
using an NTP server.
 Set system date: the user may update both date (year/month/day) and time
(hour/minute/second).
 Network Time Protocol: NTP update
The user can enter a time server address to update the equipment’s internal clock
automatically. Make sure this address can be reached by the unit; specifically, the gateway
must be properly set. Specify whether it should be synchronized continuously or periodically.
For periodic synchronization, indicate what time the daily synchronization should occur
(between 0 and 23).

Set the time zone first! Changes in the time zone affect the time that is displayed in the system time
window, so setting the zone first will eliminate the need to set the system time twice!

SNMP Agent
 SNMP configuration
The equipment enables multiple addresses to be configured for SNMP notifications. However, only
the Main Manager has the authority to acknowledge notifications. With “INFORMS” messages,
automatic answers from secondary managers are ignored by the unit.
 MIB: to download the MIB right click on the link and select “Save link as”
 SNMP Traps configuration


SNMP Notification Type / Trap Community / System Description: trap settings
Life Sign Trap / Minutes between Life Signs: sends life signs every X minutes. This trap makes it
possible to check that the unit is connected to the network.
 Trap sending test: enables the user to carry out a test according to the trap settings.
9.7.8.1
Supported SNMP versions
The unit implements an SNMP agent conforming to SNMPv1 and SNMPv2c versions. GET and SET
commands are supported, as well as GETBULK in SNMPv2c. Notifications can be transmitted in TRAP V1 or
V2c form or with an INFORM V2c type.
9.7.8.2
Notification mode
To make sure traps are received by the main recipient, the unit offers 2 methods. With both methods, traps
are sent until they are acknowledged.
 Automatic acknowledgement for sending with INFORM. These notifications are only available
with the version 2c of the protocol. This protocol checks that the manager sends the notification
to the transmitter. This process is simple and reliable, no specific configuration is required for
the manager.
 Manual acknowledgement for Traps V1 and Traps V2c. A specific OID
(“alarmPendingAlarmsalarmAck”) is extracted and its variables are sent with the trap. The

manager must then execute a SET command. This method is more complex but is the only one
that can work with the version 1 of the protocol.
The acknowledgment mode (Trap V1, Trap V2c or Inform) is identical for all alarms. See the next section
“Notifications” for additional settings.

With “SNMPv2c traps” notifications, it not possible to acknowledge traps.
In the same way, traps which do not require acknowledgment cannot be sent with the “Inform
SNMPv2c” format, even when this format is selected. This is the case with the ‘test’ trap as well as with
equipment information traps such as the ‘Equipment On’ trap.
9.7.9.
Notifications
 SNMP Actions
The user may replay traps that have not been acknowledged yet.
The user may also delete pending traps that have not been acknowledged yet.
Signal suppression in local mode:
If the box is checked, as soon as the transmitter is in local mode, SNMP GET return the
value undefined and SNMP traps are no longer sent. SNMP traps start being sent again
when the transmitter is no longer in local mode.
It is useful to prevent generating traps while in maintenance.
If the box is not checked, SNMP GET return the current value and traps are sent even in
local mode.

If the transmitter is part of an N+1 system with Nephtys, this mode must be disabled to ensure the
system will work properly.

IRT traps are configured like common traps (see previous section), with 2 additional parameters:
To enable the trap, check "Enabled" (replaces the “Do not send option” of the Common traps)
Set the priority; this information which is sent with the traps can be used by an SNMP Manager as
filter criteria for instance.

10. REMOTE CONTROL AND MONITORING WITH THE GPIO BOARD
10.1.
Introduction
This function is available when the optional standard or analog GPIO board is installed on the transmitter.
It provides an interface between ECRESO transmitters and external systems. The modules are remotely
controlled via “RC” inputs using opto isolators. Working state and alarms are sent to “RM” outputs via relays,
or “RM ANA” analog outputs on the analog board.
10.2.
Standard GPIO board
10.2.1. Description of control and monitoring functions
Control commands work when an impulsion longer than 100 ms is sent to the corresponding input.
There are eight control functions:
Power on: turns on the transmitter
Power off: turns off the transmitter
RF on: enables the RF
RF off: disables the RF
TA on: enables the TA (basic RDS)
TA off: disables the TA (basic RDS)
DSN main: enables the main DSN (basic RDS)
DSN alt: enables the alternative DSN (basic RDS)
Control commands can also be used to trigger presets. See section 9.4.2 for more details.
Outputs are relays that include a normally closed or normally open contact. When an event occurs in the
unit, the corresponding relay is activated.
Seven monitoring functions are associated with relays:
Local: indicates if the unit is in local mode
Fault: indicates a transmitter fault
Warning: indicates an alarm linked to the internal working of the transmitter (temperature, voltage…)
RF: indicates if the RF is enabled
On: indicates if the transmitter is not in standby mode
Off: indicates if the transmitter is in standby mode
VSWR: indicates if there is a VSWR error

10.2.5. Management using serial commands
A set of commands makes it possible to override the control board to modify specific RC outputs and read
specific RM inputs.
To do so, set the RC you want to control (SYS.GPIO.IN.MASK) and the RM you want information from
(SYS.GPIO.OUT.MASK).
When these commands are used, the control board cannot monitor nor control them.
NAME

manually (see SYS.GPIO.IN.MASK)
R/W
XX X=[A..F;0..9]
Enables the corresponding RM when
manually (see SYS.GPIO.OUT.MASK)
XX X=[A..F;0..9]
Sets the RC control either by the control board or
manually. Hexadecimal code: each bit corresponds to
an input. Ex: A1 (10100001) indicates the RC 1, 6 and 8
are managed manually
XX X=[A..F;0..9]
Sets the RM control either by the control board or
manually. Hexadecimal code: each bit corresponds to
an input: Ex: 21 (00100001) indicates RM 1 and 6 are
managed manually.

You must convert the hexadecimal value in binary, ie 8A=10001010, which indicates that RC 2, 4 and 8 are
activated.
To control RM 3 and 5, convert the binary value 00010100: you get 14 as per the above table. You must
then send the command:
SYS.GPIO.OUT.MASK=14

APPENDIX E: EMR & SECURITY
E.1. Transmitter Notification Protocol
As soon as the EMR option is activated in the transmitter, or after a restart, the Transmitter’s IP Module will
send a notification packet to the EMR server. Then an update to this notification packet will be sent every 60
minutes (or any configured interval).
The notification packet is a JSON (www.json.org) payload transferred into an HTTP/S POST message,
encrypted with the standard TLS protocol. In case of connection failure the transmitter will not retry until the
next scheduled attempt.
In case of an alarm inside the transmitter, a notification packet will be issued immediately.
JSON packet payload contains only technical information related to the transmitter status and
measurements.
In order to succeed the transmitter needs a route to the Internet (setting the gateway accordingly), and an
unfiltered outbound access to https port. Firewalls are usually not restricting outgoing connections, so no
specific changes have to be done. DNS access is also required to reach the EMR server, but as a common
service, DNS protocol is almost always authorized by firewalls. Note that the transmitter factory settings use
Google’s public DNS servers (see https://developers.google.com/speed/public-dns/), so you don’t have to
provide your own.
Private network
Transmitter
Internet
One-way connection
EMR Server
E.2. EMR Server Security
Sensitive data is stored in the server database in a protected form. All customer private information, and
transmitter nature and localisation are stored encrypted. In case of a theft of the database files or backups,
no useful information will be readily available; the effort that would be required to breach the security would
be disproportionate compared to the value!
User passwords are not stored at all in the server. Authentication is done using the HMAC protocol (see
http://en.wikipedia.org/wiki/Hash-based_message_authentication_code). Stored password hashes are
encrypted
using
PBKDF2
protocol
as
recommended
by
USA
NIST
(see
http://csrc.nist.gov/publications/nistpubs/800-132/nist-sp800-132.pdf).
EMR Web Server automatically uses the secured HTTP/S protocol, and cannot be accessed with an
unsecured connection.
