Table 1: Description of LED Status Indicators
NOTE: In addition to the LEDs above, the Ethernet connector
has two embedded LEDs. A flashing green indicates
Ethernet data activity. A yellow indicates 100 Mbps oper-
ation.
All units must meet the basic requirements listed below for proper
operation. Check these items first when troubleshooting a system
problem:
• Adequate and stable primary power
• Secure connections (antennas, data and power)
• A clear transmission path between associated units
• An efficient, properly installed antenna system
• Proper configuration of unit settings
• Correct interface between the unit and other equipment
The unit’s LED indicator panel can provide useful information when
troubleshooting. Refer to Table 1 for LED indications.
3.1 Event Codes
When an alarm condition exists, the unit creates a message read-
able on a connected PC. Consult the Technical Manual for details.
The COM port (Figure 7) is commonly used to connect an external
DTE telemetry device to the unit, supporting either the RS-232 or
RS-485 (balanced) format, depending on how the device is config-
ured. The unit supports data rates of 1200, 2400, 4800, 9600,
19200, 38400, 57600, and 115200 bps (asynchronous data only).
This connector mates with a standard RJ-45 plug available from
many electronics parts distributors.
4.0.1 Pin Descriptions—RS-232 Mode
Table 2 provides pin descriptions for the COM connector when
operating in RS-232 mode. Refer to the Technical Manual for
RS-422/485 descriptions.
