UPTIME

Returns the amount of time the A440 Wireless Modem connected to the gateway has been operational.

None.

The amount of time the wireless modem has been in operation.

None.

uptime

Up 230 day(s), 10 hour(s), 14 minute(s)

OK

NOP

This command is deprecated in emu3ap. It has been included for compatibility purposes, but always returns OK. The A840 Telemetry Gateway’s software is stored in its internal Flash EEPROM.

HELP

Returns all the available commands in the emu3ap software.

None.

A list of commands.

QUIT

Exits the emu3ap software. If you were logged in as the user adv , you will be returned to the Linux login prompt. Otherwise, you will be returned to a Linux shell.

None.

Nothing.

You can use the EXIT command with the same result.

Direct Radio Commands

This category describes several commands that allow the host to communicate directly with the remote stations or other base stations. These commands take a longer time to complete. The exact amount of time depends on how the end-station is routed and how much time it takes the frames to travel from one station to another.

Operations at the Application Level

33

The direct radio commands return by default results such as OK or a specific error number. Complete details about the direct radio commands can be found in the user manuals for the respective devices (A730MD, A720, A723, and A733).

PING

Returns information about the specified device such as the RF levels, the date and time of the internal real-time clock of the station, the software version in the station, and the number of reserved bytes.

The RTU’s ID.

A string or an error message (for example, ERROR 35 means timeout). The strings and parameters returned depend on the remote device type. Following is an explanation of the information returned:

• Incoming RF is the level recorded by the receiving station.

• Outgoing RF is the level at which the sending station received the requesting station.

• Pout represents the output power of the transmitter while it is sending the answer to the ping frame.

• The date/time represents the actual value of the local realtime clock.

• Ver is the software version of the RTU.

• Clk, stk, and cop contain Adcon-specific information.

• The uptime represents the time the device has operated since the last reset or internal watchdog reset.

• The battery and internal temperature are self-explanatory.

• RSSI (relative signal strength), PMP (power management parameters), and Slot are the current settings of the device.

None.
