BackGeode GNS3 / GNS2 battery gauge commands
28 Aug 2020
You can use the Geode Connect's terminal screen to send messages relating to the battery. The messages detailed below are valid for the Geode GNS2 and GNS3 models.
The messages below are specific to the Geode devices, which is noted by the initial elements $JRELAY and $PJSI (JRELAY= relays a custom message to other internal components, such as the battery controller, P=proprietary, and JSI=Juniper Systems).
To check battery status and charge, use this command:
$JRELAY,A,$PJSI,BAT
To check battery reporting interval, use the command:
$JRELAY,A,$PJSI,CFG,BAT
Battery Charge Level & Status
Use the following command to receive a report of the battery’s charge level and status:
$JRELAY,A,$PJSI,BAT
The elements of this message are described in the following table.
| Elements | Description |
|---|---|
| $JRELAY | Relays a custom message to other internal components, such as the battery controller |
| PORTx | Message ID $ = message header character P = proprietary sentences JSI = Juniper Systems |
| BAT | Identifies the message as relating to the battery |
The receiver’s response will be in a form similar to the following message:
$PJSI,BAT,a,b,c,d*CC<CR><LF>
The elements of this message are described in the following table.
| Elements | Description |
|---|---|
| $PJSI | Message ID $ = message header character P = proprietary sentences JSI = Juniper Systems |
| BAT | Identifies the message as relating to the battery |
| a | The time is given in UTC in the form of HHMMSS.SS (hours, minutes, seconds) |
| b | This number identifies which battery the following information applies to. The Geode’s battery is always 1. |
| c | The percentage of charge in the battery (0 – 100). |
| d | Status of the current battery reported in a number with the following meaning: 0—not present 1—Charging 2—Discharging 3—Error condition |
| *CC | Data checksum value |
| <CR><LF> | These elements literally stand for carriage return and line feed. Together they mean that a new line will begin. |
As an example, a returned message might look like the following:
$JRELAY,A,$PJSI,BAT,082710.00,1,52,2*15
This example message tells that the custom Juniper Systems message was sent through serial port A at 8:25:10 UTC. Battery 1 holds a 52% charge and is currently discharging. The data checksum value is *2B.
Configure Battery Reporting Interval
Use the following message to adjust the battery reporting interval output refresh rate, i.e., the interval configuration command.
$JRELAY,A,$PJSI,CFG,BAT,a
The elements of this command are described in the following table.
| Elements | Description |
|---|---|
| $JRELAY | Relays a custom message to other internal components, such as the battery controller |
| PORTx | Indicates the port where the message will be sent |
| $PJSI | Message ID $ = message header character P = proprietary sentences JSI = Juniper Systems |
| CFG | Identifies the message as relating to configuration |
| BAT | Identifies the message as relating to the battery |
| a | Enter a numeric value to set the update rate. Entering 0 will disable the battery reporting messages. Enter the following decimals to achieve the indicated reporting interval. 1—update every 1 seconds 0.5—update every 2 seconds .2—update every 5 seconds 0.1—update every 10 seconds 0.0667—update every 15 seconds 0.02—update every 50 seconds 0.01—update every 100 seconds 0.0083—update every 120 seconds |
As an example, a command message with element values follows:
$JRELAY,A,$PJSI,CFG,BAT,1
This example shows that a custom Juniper Systems message was sent through serial port A to configure the battery to report every second.
