Online Diagnostics
If enabled, diagnostics information is sent at the beginning of each transmission. Diagnostics information is invisible to
user data except for the increase in RTS/CTS delay of 11ms (at 9600 bits per second). The default value is Enabled
(checked).
Note: All units in a network must use the same setting.
Diagnostics from the last 15 stations heard are stored in each unit. These values are read using the Offline or Online
Diagnostics window.
Transmitted information includes:
• Short ID
• Supply Voltage (in Volts)
• Internal Temperature (in Celsius)
• Forward and Reverse Power (in Watts)
• Received Signal Strength (in dBm)
Output Online Diagnostic Data to Setup Port
Allows the user to configure the Guardian Modem to output online diagnostics through the Setup Port. The default
value is Disabled (unchecked).
Repeater Mode (Extended T1 RTS-CTS)
The Repeater Mode option extends transmitter turn-on time to allow use in a repeater network. The default value is
Disabled (unchecked).
Extended Turn-off (T2)
The Extended Turn-off option extends transmitter turn-off time to enforce a quiet period at the end of each
transmission. Select "Enabled" if data equipment does not clearly terminate each data frame and is susceptible to
extraneous bits (dribble bits) at the end of data transmission. The default value is Disabled (unchecked).
Values are: 4800 bits per second = 16 ms; 9600 bits per second = 8 ms; or 19200 bits per second = 4 ms
