CHAPTER 3

Using terminal commands

RETURNS A list of a device’s internal variables:

ID INFO rf_in rf_out date time ver clk stack cop

batt temp days_uptime min:sec_uptime rssi pmp_low

pmp_high type slot samples err_level

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.

• 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:

• 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

— 4 for A733
