When no I/O element is enabled, AVL packet comes with GNSS information only. After enabling I/O element(s) AVL packet contains current value(s) of enabled I/O element(s) along with GNSS information.<br/>If the device is connected to configurator all current I/O values are displayed in ''Current Value'' column.<br/>''Priority'' field allows enabling I/O elements and setting them a priority so they are added to the data packet, which is sent to the server. By default 10 I/O elements with low priority are enabled: ''Ignition'', ''Movement'', ''Data Mode'', ''GSM Signal'', ''Sleep Mode'', ''GNSS Status'', ''GNSS PDOP'', ''GNSS HDOP'', ''External Voltage'' and ''Speed''. ''Priority'' level (AVL packet priority) can be <span style=color:#F6A83E>Low</span>, <span style=color:#F6A83E>High</span> or <span style=color:#F6A83E>Panic</span>. All records made by {{{model|FMB640}}} are regular, and regular packets are sent as low priority records. When ''Low priority'' event is triggered, {{{model|FMB640}}} makes an additional record with an indication that the event was caused by an I/O element change (depending on ''Operand'' configuration). When ''High priority'' is selected, module makes an additional record with high priority flag and sends event packet immediately to the server using GPRS. ''Panic priority'' triggers same actions as ''High priority'', but if GPRS fails, it sends an AVL packet using SMS data if SMS data sending is enabled and the number is provided in ''SMS/Call Settings''.<br/>''High'' and ''Low'' levels define I/O value range. If I/O value enters or exits this range, {{{model|FMB640}}} generates an event. ''Operand'' parameter defines when to generate event: ''On Exit'', ''On Entrance'', ''On Both'', ''On Hysteresis'' or ''On Delta Change''.<br/>When ''Event Only'' is selected, I/O element status value will be appended only to eventual records, otherwise I/O element status value will appear in each AVL record.
