ELETTRONICA
2. Connection via Modem
The telemetry option supports connectivity to the whole range of
units of RVR’s TEX-LCD and TEX-LIGHT family of products.
This section describes the features introduced with version /TLW-TEX2HE &
/TLW-TEX3HE and the necessary steps for their proper configuration.
The telemetry option supports:
• Remote alarm reporting by sending SMS messages through a GSM modem or through
a PSTN modem (dial-up) by sending an alarm message string to a connected PC.
• Telemetry, with all equipment parameters sent to the “TELECON” software through
an (RS232);
• Remote controlling through an (RS232) connection to the “TELECON” software or
through certain predetermined SMS messages if connected to an external GSM
modem.
• Telemetry via internet through 10Base-T LAN/Ethernet network.
2.1 Remote alarm monitoring
The list of parameters monitored for the alarm management are:
• Exciter output power (forward power good “PgD”);
• Reflected power at the exciter (reflected power good “PgR”);
• Temperature state (OVER TEMPERATURE);
• Audio Signal Level;
• Mains voltage state (present or missing).
Factory default settings are as follows:
ALLARMI TEMPI SOGLIE
Potenza Diretta (Fwd Pwr) 25 Sec. Power Good (PgD)
Potenza Riflessa (Rfl Pwr) 25 Sec. Power Good (PgR)
Audio 325 Sec. 20 kHz
Sovratemperatura 25 Sec. 72°C
Alimentazione di rete (Mains) 25 Sec.
Table 2.1
An inhibit time (start time) after power-on is provided to ensure false alarm
prevention. When this inhibit time times out, the thresholds of alarm generation
parameters are checked and remote alarms are sent if needed.
Alarm generation technique is outlined in the figure below; remote alarm delay,
i.e. the amount of time the system waits before issuing a remote alarm after an
alarm condition occurs is indicated in table 2.1. When appropriate, a new line is
added to the alarm log stored in /TLW-TEX2HE & /TLW-TEX3HE , up to six lines
maximum.
