The formats for the above parameters are as follows:

•rf_in and rf_out as a decimal

•date as dd/mm/yyyy

•time as hh:mm:ss

•ver as x.x

•clk, stack, and cop as decimal; they represent internal housekeeping parameters and are implementation dependent (the A720 uses cop to number watchdog occurrences, but clk and stack are currently undeﬁned for the A720; for the A723 clk returns the SST – Sensor Sampling Time value, default 2)

•batt as battery level using the standard voltage conversion equation (0 is 0 volts, 255 is 20 volts)

•temp as internal temperature in the A720 housing, which is device dependent. The precision of the sensing element is very low (±4°C), but it is sufﬁcient for battery power management (charge/discharge). To compute the actual value (in °C), the following equation must be used:

1087

Temp = internalTem p • ----------- – 275

255

•days_uptime in days; together with min:sec_uptime, it represents the amount of time the device is up without a reset or watchdog

•min:sec_uptime in minutes:seconds format

•rssi as decimal; it is the programmed value with the RSSI command

•pmp_low and pmp_high are the programmed values with the PMP command

•type is used to represent the device type; following types are assigned currently:

—0 for A730MD

—1 for A720

—2 for A730SD

—3 for A720B
