Modem
DT8xM models only
This page contains settings for the integrated modem. The page is divided into four tabs:
• The General tab contains basic connectivity settings. If the SIM has a PIN set then it must be entered here.
• This is also where the Access Point Name (APN) is set. The DT80 includes a list of APNs used by certain
mobile carriers. If one of the "set by SIM" options is selected then the DT80 will attempt to locate the correct
APN settings based on the inserted SIM card. If this doesn't work (an "APN not set" error is returned when the
DT80 first attempts to connect to the Internet) then you will need to select Manual and obtain the correct APN
settings from your mobile carrier. See Manual Configuration (P211) for more details.
• The Power tab is used to configure communications session timing parameters – such as when a session
should start and how long it should persist for – as described in Session Timing Settings (P223)
• The Session connection tab deals with communications session error handling. See Session Failures (P224)
for more information.
• Finally, the Network capabilities tab allows you to restrict the modem to either 3G or GSM operation, or restrict
it to particular frequency bands. These settings are seldom required as the DT80 will automatically connect to
the best available network that has adequate signal level. However, if you wish to force the DT80 to connect to
a particular mobile network, and you know its frequency band, then these settings can provide a way of doing
this. See also Network Selection (P220).
For regular models (no integrated modem), this page contains selected settings for an external modem. These
correspond to profile settings in the
HOST_MODEM section.
Modem DDNS
DT8xM models only
This page contains settings for the DT80's Dynamic DNS client, which allows you to access the logger from the Internet
using a custom domain name. These settings are described in Dynamic DNS (P213
).
Startup
The settings on this page control the DT80's behaviour following a hard reset (HRESET command, power failure,
hardware reset switch, or abnormal reset).
By default, the current job will be reloaded following reset, but this can be disabled by unticking the Automatically
activate checkbox.
You can also make the DT80 restore all digital outputs (including the latching relay output) to their previous state
following reset (by default they will be reset to the "off" state), using the Maintain digital outputs checkbox.
Keypad Functions
This page allows up to ten commands to be added to the function menu that is displayed when the Func key is pressed.
To add or edit a label or command click on the appropriate table cell, enter the new text then press Enter or click on
another cell. See also User Defined Functions (P121).
LCD
The options on this page are mostly intended for applications where the display is visible but the keypad is not
accessible. The Auto-scroll option will cycle through all defined channels on the display at the specified rate, while the
Auto-dismiss option will automatically acknowledge any warning messages that may be shown on the LCD after they
have been displayed for the specified time. See also Display (P118).
Calibration
This page contains a control to set the voltage drift threshold (in microvolts) for triggering an automatic recalibration of
the DT80's analog system. Automatic recalibration reduces the effect of temperature changes on analog measurements.
See Calibration and Characterisation (P371).
WiFi
DT8xW models only
This page contains WiFi setting for both operating mode (Access Point or Client). In Access Point mode, SSID name and
password could be set. It is also possible to set automatic IP assignment though DHCP setting.
While in Client mode, you may select the available network from the list and supply the password. Then setup a fixed IP
address or follow DHCP assignment from the network where this logger connected.
