B Test the text message configuration
1. Reconnect the GSM modem to the Modem System cable,
and ensure it’s powered up.
2. Briefly connect together the two DIN rail terminals (green and yellow wires)
e.g. with a piece of bent wire. This simulates a contact closure in the logger relay.
Within a minute or two you should receive a text message at your mobile number.
C Program the logger’s relay
Refer to the GP1 or DL6 Quick Start Guide and DeltaLINK online Help for information
about programming the logger.
In a
