Description
System
Low Lithium Battery Alarm: When LL (low lithium) is displayed, the lithium battery
LL
voltage is below 2.5 Vdc. A new lithium battery measures approximately 3.6 Vdc.
Low Charger: When LC (low charger) is displayed, the XSeries
LC
voltage is (+) 0.4 Vdc, or is less than or equal to the battery voltage.
Communication Protocols
Transmitting Data: Sending a response
Receiving Data: Processing request
Nak: Negative acknowledgement with packet list
+
Ack: Positive acknowledgement of receipt of request
Waiting for Ack: Waiting for response after transmission
Exception Alarm Processing
ID Recognized: Recognized and receiving request
Listen Cycle: Flashes if this remote port is active and running Totalflow Remote
Protocol. Flashes in sync with the listening cycle that occurs at 1, 2 or 4 second
intervals. When the baud rate is faster than 2400, then the flashing symbol may not be
visible. The annunciator will remain on listening cycle if the listen cycle is set to zero.
