FAQ#051 – Which communication interfaces are possible to use with miniOMNIAlog?
Only the internal GPRS module is supported.
FAQ#050 – Are SMTPS (SSL) and SFTP supported by miniOMNIAlog?
miniOMNIAlog can be configured to send readings files via e-mail or on FTP server, using simple SMTP authentication protocol or FTP simple protocol. The protocols SFTP and SMTPS (SSL) are not supported. miniOMNIAlog does not support security layer. miniOMNIAlog also does not support encrypted authentication (eg. NTLM, MD5 etc.). However, SISGEO supplies the datalogger carrying […]
FAQ#049 – Does miniOMNIAlog support remote connection?
No, to manage (i.e. to configure) a miniOMNIAlog it is necessary to connect a PC directly through an USB cable.
FAQ#048 – Is it possible to use an Apple Mac to manage a miniOMNIAlog?
No software is necessary to be installed: simply connect the PC to the USB port and establish a dial-up PPP connection.Last Apple Mac Operating System seems not support anymore dial-up PPP connection.
FAQ#047 – Is it possible to change channels configuration of miniOMNIAlog?
Power supply type (internal batteries or external power supply), the measure type of each analog channel (current, voltage, NTC, Wheatstone bridge) and the presence of the GPRS module are configured at the factory. The user is not able to modify these settings.
FAQ#046 – OMNIAlog: something to know to communicate with optical fiber technology
The optical fiber interface you can find in SISGEO catalogue is an ethernet switch with 4 10/100Base-TX ports (to link other LAN devices, in addition to OMNIAlog) and 2 100Base-FX ports (store and forward architecture). This interface is suitable for multi-mode fibres (50/125µm and 62.5/125µm) that allow lengths of maximum 2 km; for longer sections, you […]
FAQ#045 – Using the OMNIAlog system, is it necessary the grounding system?
To make efficient and effective the protections of miniOMNIAlog, it is INDISPENSABLE to have a grounding system. The ground is no longer necessary to guarantee quality-measurements (“measurement ground”), but it is considered only as “functional ground”.
FAQ#043 – Can OMNIAlog acquire 8 or 16 instruments, without any multiplexer boards?
OMNIAlog is nominally a datalogger with 8 differential channels. For every one of the 8 differential channels it is possible to connect up to: * channels with power supply shared on the same channel
FAQ#042 – Is it possible to connect a rain gauge to OMNIAlog datalogger?
Yes, the rain-gauge is connected to one of the two digital input placed in the posterior side of OMNIAlog. For the system autonomy, it is necessary to bear in mind that OMNIAlog connected to a rain-gauge it is always in measurement mode. Therefore, it will never go in “sleep-mode”. OMNIAlog takes a sample of the […]
FAQ#041 – 3G/2G modem or 4G/3G router: which technology should be chosen?
The use of 3G/2G modem is allowed only in these events: With 3G/2G modem, the remote connection has to be considered an emergency connection. Pages uploading is extremely slow in case of inadequate signal quality. The remote connection requires a pc equipped with a GSM modem or an analogic modem connected to the phone network (not digital […]
FAQ#040 – Does the management of 4G/3G router change according to the power supply of OMNIAlog?
There are two communication alternatives, varying according to the power sources available on site:
FAQ#039 – 4G/3G Router: which to choose?
In order to connecting to OMNIAlog using the Internet, it is necessary to install a 3G router inside the OMNIAlog box and to insert a SIM card (with APN) into the router. This card should be Internet enabled (SIM card not included). DUTIES: 1 – Dynamic IP traceability 2 – Incoming traffic block (it depends from the […]
