Key-Value record

The Key-Value record allows entry of Keys and a value for that key.

The following table shows the additional records provided when the key-value record is included with Command Packet 64h.

Notes

RtxCtrl

Bit 0 = xFill
Bit 1 = RTX
Bit 2 = xFill-RTX
Bit 3 = GVBS

The values are derived from bits to enable (0) or disable (1) these RTX controls.

For example, to disable RTX and GVBS, set bits 1 and 3:

00001010 binary = 10 decimal = 31 30 ASCII HEX

Thus, the key-value record will be:

5E 0B 52 74 78 43 74 72 6C 00 31 30 00

IonoMitigationMode

0 = Disable (30 ASCII HEX)
1 = Enable (31 ASCII HEX)

IonoGuard controls, for example, by enabling it, the key-value will be:

5E 15 49 6F 6E 6F 4D 69 74 69 67 61 74 69 6F 6E 4D 6F 64 65 00 31 00

RNDISIp

0–255 (as ASCII HEX)

Set the third byte of RNDIS IP, 192.168.X.1, default 144. The key-value record will be:

5E 0C 52 4E 44 49 53 49 70 00 31 34 34 00

AutoReboot

{Enable},{Seconds},{Reset timer}

0-Disable
1-Enable

Set the auto reboot timer, for example, enable a timer of 43200 minutes. The key-value record will be:

5E 17 41 75 74 6F 52 65 62 6F 6F 74 00 31 2C 32 35 39 32 30 30 30 2C 30 00

When the Reset Timer is set (using a HEX value of 31), the countdown timer will reset (to 43200 minutes in this case).

EpochTplate

{Epoch},{Tectonic plate},{ITRF to RTX},{ITRF Epoch}

Epoch: 1-Current; 2-Fixed

Tectonic plate: 0-Auto

ITRF to RTX: 0-Disable; 1-Enable

ITRF Epoch: 200500

Set the ITRF Realization, for example, fixed epoch, and apply ITRF to RTX, tectonic plate in auto mode. The key-value record will be:

5E 19 45 70 6F 63 68 54 70 6C 61 74 65 00 32 2C 30 2C 31 2C 32 30 30 35 30 30 00

For a list of available tectonic plates, see the GSOF message: Position Type.

For fixed epoch, only ITRF Epoch 2005 is supported.
