CAUTION! -Contact your telephone service provider for GSM and GPRS service costs especially when using RTU-LP with a sim issued by a country other than the one in which it is used (international roaming). -It is best to estimate telephone costs before setting up LP-RTU. - Page 7 (from 5 to 30 seconds) and the time due to any server login attempts. -Check the data quantity sent via internet and SMS before using RTU-LP. Please remember that mobile phone service providers also consider the entire communication that permits file transmission (and thus data transmission overhead, the number of connection attempts, etc.) and not just the dimensions as data traffic in each transaction.

Page 14: Power Control For External Sensors
Seneca recommends to use an external battery (rechargeable) for power up external sensors, the power is connected to the sensor 1 through the DO1 and to the sensor2 through DO2. There is no need to command the DO because the firmware can power up autonomously the sensors before reading. -

Page 16: Device Overview
USER MANUAL – RTU-LP-ST 4. DEVICE OVERVIEW The RTU-LP-ST is an ultra low power device, the RTU is always sleeping (with the modem OFF) but when an event is registered the RTU can Wake-up and send data. It’s also possible to configure the device to send data at a time interval or wake up the board at fixed time leaving the modem ON for minutes (for receiving commands). -
Page 17: Wake Up Window
USER MANUAL – RTU-LP-ST 5. WAKE UP WINDOW When the RTU is in sleep mode the SMS cannot be reached because the modem is switched off for energy saving purpose. For sending command SMS to the RTU it’s possible to configure a wake-up window where the RTU can switch ON the modem and read/execute the command SMS. - Page 18 USER MANUAL – RTU-LP-ST T: totalizers values: dddddddddd = Totalizer 1 value eeeeeeeeeee = Totalizer 2 value ffffffffff = Totalizer 3 value gggggggggg= Totalizer 4 value BAT: Battery Voltage xx.xV battery Voltage measured with modem in ON state TEMP: Temperature xx.xC Temperature in °C...

Page 31: Setting The Telephone Sms Character Alphabet
Setting the Telephone SMS Character Alphabet Some Smartphones send SMS with UNICODE characters instead of using the GSM alphabet. RTU-LP only runs SMS commands with GSM alphabet. In most cases, SMS characters are set to AUTO alphabet by default. If the RTU does not recognise any SMS command, check the alphabet used by the phone. -

FIRMWARE UPDATE In order to include new functions, the system includes a firmware update option. For updating the firmware use the Easy RTU-LP software and the “UPDATE” cable (supplied). For updating the firmware the firmware update cable must be used. - Page 38 USER MANUAL – RTU-LP-ST 0.525 mAh + (0.375mA*24h)=9.525 mAh And so, sending one SMS every day the total consumption is : 10400 mAh/9.525mAh for day= more than 1091 days = about 3 years CAUTION! If the GSM field is low the RTU can try up to 3 times to send a SMS or a file in FTP.
