1. General Description
The telemetry option, whether internal or external, 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 /TLC version (option with
external telemetry without modem) and the necessary steps for their proper
conguration.
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 connection.
Remote controlling through an RS232 connection to the “TELECON” software
or through certain predetermined SMS messages if an external GSM modem
is connected.
Telemetry on internet across 10Base-T LAN/Ethernet network through TCP-IP
-INT/TEX external interface connection.
1.1 Remote alarm monitoring
Alarm generation parameters are listed below:
Exciter output power (forward power good “PgD”);
Reected power at the exciter (reected power good “PgR”);
Temperature state (OVER TEMPERATURE);
Audio Signal Level;
Mains voltage state (present or missing).
Factory default settings are as follows:
ALARM TIME THRESHOLD
Forward Power (Fwd Pwr) 25 Sec. Power Good (PgD)
Reflected Power (Rfl Pwr) 25 Sec. Power Good (PgR)
Audio 325 Sec. 20 kHz
Over Temperature 25 Sec. 72°C
Mains Power (Mains) 25 Sec.
Table 1.1
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 gure 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 1.1. When appropriate, a new line is added
to the alarm log stored in /TLC, up to six lines maximum.
