REMOTE CONTROL AND MONITORING WITH THE GPIO BOARD
10.1.
Introduction
This function is available when the standard digital, analog
or digital with “Fault memory”
optional 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.
The GPIO board can also be used with the transmitter presets. See section 8.4.2 Presets for more details.

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) - in simple drive / Preselect1: sets drive 1 as main drive
–
in dual-drive
•
TA off: disables the TA (basic RDS) - in simple drive / Preselect2: sets drive 2 as main drive
–
in dual-drive
•
DSN main: enables the main DSN (basic RDS) - in simple drive / Auto mode: switches to auto mode
–
in dual-
drive
•
DSN alt: enables the alternative DSN (basic RDS) - in simple drive / Manual mode: switches to manual mode
–
in dual-drive
Control commands can also be used to trigger presets. See section 8.4.2 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 - in simple drive / Switchover: indicates if a switchover has occurred
–
in
dual-drive / Reserve OK: indicates if the reserve is ready
–
in dual-drive
•
On: indicates if the transmitter is not in standby mode - in simple drive / Preselect1: indicates if the drive 1 is
set as main drive
–
in dual-drive
•
Off: indicates if the transmitter is in standby mode - in simple drive / Preselect2: indicates if the drive 2 is set
as main drive
–
in dual-drive
•
VSWR: indicates if there is a VSWR error - in simple drive / Auto: indicates if the control unit is in auto mode
–
in dual-drive
