7. REMOTE CONTROL AND MONITORING WITH THE GPIO BOARD
7.1.
Introduction
This function is available when the 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.
7.2.
Description of control and monitoring functions
Control commands work when an impulsion longer than 100 ms is sent to the corresponding input.
There are 8 control functions:
•
Power on: turns on the transmitter
•
Power off: turns off the transmitter
•
RF on: enables the RF
•
RF off: disables the RF
•
Config 1 to 4 : retrieves the configuration in memory (from 1 to 4) (future version)
Outputs are relays that include a normally closed or normally open contact. When an event occurs in the
unit, the corresponding relay is activated.
Six monitoring functions are associated with relays:
•
Local: indicates if the unit is in local mode
•
Default: indicates a transmitter default
•
Warning: indicates an alarm linked to the internal working of the transmitter (temperature, voltage…)
•
RF: indicates if the RF is enabled and/or if there is a 3 dB error
•
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
