• Check local RTU port is correctly configured. Eg.
Type=PSTN, Baud Rate=9600, Pre Tx=0, Post Tx=0
(PSTN modem or GSM) or Post Tx=400 ms (for 3G
modem). Ensure correct Init String is being used for the
PSTN port (select the Configure button).

Timeout=2000ms (or greater) and that the correct port
number (as configured above) is being used to dial the

added for the Target (remote) RTU address.
• Create a test site - create a Network List entry for Target
RTU 100. Then add a phone number of a local phone
(eg. a mobile phone) for Target RTU 100 in the Phone
Directory.
• Test if the local phone will ring, use Utilities, Dial Site to
dial site 100.
•
Manually dial the phone number of the remote RTU using
a local phone to check that the remote modem will
answer.
• Check if the local RTU will connect to the remote RTU by
using Utilities, Dial Site to dial the remote RTU. Ensure
the configuration for the remote RTU is loaded in
Toolbox. Once connected, select the configuration
window of the remote RTU and then select View, RTU
