LOS Radio/ SSP / RS-485 Settings
This is the LOS Radio settings screen. There are only three settings here. The Tx Normal Rate is
the rate at which alarms are transmitted when no sensors are in alarm, and the Tx Alarm Rate
which is the rate used when a sensor is in alarm. They can be set to 00:00:00 to inhibit timed
alarm transmissions. Disable Alerts may be checked to prevent messages to be sent out the port
when the system enters the alert state.
The LOS Radio only supports sending alarms to PC Base Stations using SSP (Sutron Standard
Protocol).
The SSP and RS-485 options are very similar to the LOS Radio option. The primary difference
being that SSP assumes a direct (SSP Only) serial connection between two devices, and RS-485
assumes there is an RS-485 connection. The difference is in how the control lines are used, but
the options are the same.
Data Modem Settings
This is the Data Modem settings screen. When a alert occurs each phone number is tried in
sequence starting with Phone #1, until an acknowledgement occurs. Or until the # Redials has
been attempted on each number. The redial delay causes a pause between each redial attempt.
The Data Modem connection support two types of alarm messages. If a PC Base station is
detected, an SSP alarm is sent, otherwise a simple text message is sent and a prompt is made
asking for the alarm to be acknowledged.
