E-EQ-RX2RG-B RX2 Reference Guide
Power Supply Options
There are several options available for powering the RX2.
• An internal battery is optional. The internal battery is designed to provide a
minimum of 9 hours operating time for the RX2. The internal battery pack recharges
in less than 6 hours using the specified battery charger.
• The RX2 can be hooked directly to 12VDC power. DC power DOES NOT recharge
the RX2’s optional internal battery.
• An optional DC to DC power supply can be used to convert 24 to 60 VDC input
power to 12 VDC output power for the RX2. DC power DOES NOT recharge the
RX2’s optional internal battery.
Battery Status
If an RX2 is operating on battery power, the battery status can be monitored in several ways:
• Power LED – The power LED is flashing green (or solid green while booting) when
battery power is good. When battery power is low, the LED is flashing red (or solid
red while booting).
• Buzzer – By default, the low battery buzzer sounds when battery power is low.
• SNMP – The SNMP agent can be queried by an SNMP manager to determine the
status of the battery (please see Chapter 4, “Application Development” for details).
• API – An API is provided to monitor battery life. Applications can call this API to
monitor battery status (please see Chapter 4, “Application Development” for details).
Note: The buzzer can be turned off using the Volume and Sounds option in the Control Panel.
See Chapter 3, “System Configuration” for details.
When the battery status is good:
• The Power LED is flashing (booted) or solid (booting) green.
• The low battery buzzer is off.
• The SNMP agent returns Good (1) for battery status.
• The API returns BATTLIFE_GOOD = 1 for battery status.
When the battery status is low:
• The Power LED is flashing (booted) or solid (booting) red.
• The buzzer sounds in approximate one second on, one second off intervals (see Note,
above).
• The SNMP agent returns Low (2)
• The API returns BATTLIFE_LOW = 2 for battery status.
When the battery status switches from good to low, there is approximately 30 minutes of power
left in the RX2 battery. Until the point the battery is exhausted the RX2 and its RFID reader
function normally. If the battery is not recharged before it is depleted, the RX2 automatically
shuts down.
If time does not permit the recharging of the internal battery pack, a DC power connection must be
provided.
