Relay On Time
The duration that the relay remains on when switched.
For example, if the first communication for each day is at 06:00h, then every 1 hour until 23:00h, and the
relay is to be on for a period of 15 minutes (900 seconds), the entries would be:
Enable Sleep
If this option is enabled, the logger will return to its ‘Sleep’ mode when the keypad has not been used, or
external communications have not taken place, for a period of 1 minute.
This option should always be enabled under normal circumstances to conserve
power consumption. It is recommended that this option be only disabled if the
logger is operating from a permanent power supply and it is desired that the
display is always visible.
6.3.2.2 Radio Cfg
These settings only apply to radio communications using the internal FSK modem, and enable certain
parameters to be set.
Baud Rate
{1200, 600, 300}
This setting specifies the rate at which data will be transferred across the radio link. The default setting of
1200 should not be changed unless necessitated by failed communications due to a poor signal etc.
Lead-In
{1.5 secs, 2.0 secs, 2.5 secs, 3.0 secs}
There is provision here to increase the lead-in time. This should only be necessary under normal
circumstances if the transmission is passing through a repeater network, or the logger itself is acting as a
gateway/repeater.
