All keywords begin one blank character after a comment introducer, which simplifies parsing by the loader application. Comment lines which do not have one of the keywords are ignored and can be used to provide additional information.
The keywords must all be present before the first S-Record line.
Each parameter is expected to begin immediately following the ‘:‘ character of each keyword.
All header keywords must be present. The list is not meant to establish a specific order.
The VERS parameter reports the version of the firmware to the loader. This string matches the value to be reported by the firmware for dilmageVersion and dlActivelmageVersion. The version string may be used as part of the dlDownloadKey. See dlDownloadKey for additional information.
The DESC parameter reports the description of the firmware to the loader. This string matches the value to be reported by the firmware for dilmageDescription and diActivelmageDescription.
The VERS and DESC keywords must match that which is to be reported by the device. The corresponding strings are expected to be embedded in the device by some means. The strings may be embedded in the firmware image or possibly part of the SO record which is then stored. The SO record format is vendor specific.
The TO, Ti, T2, and T3 parameters specify the time delays described in the download example for multiple transponders. The delays are specified in units of milliseconds. These delays represent minimum values.
The DEVICE-KEY value is used to set dlDownloadKey. This value must match diDeviceKey of the active firmware image for the device specified by dlDownloadDevice (and therefore the DEVICE keyword). Unless the correct string is written to dlDownloadKey, the transponder will not permit a download sequence to commence.
The DEVICE-KEY minimum string definition starts with the first 3 octets of physical address (the vendor’s OUI) as a hexadecimal ASCII string. This ensures no units will accidentally accept firmware from the wrong vendor. Additional octets may be specified after this 6 byte prefix field by each vendor. This string must match that which is embedded in the device, and can be confirmed via diDeviceKey. It is expected that all firmware images for one device will have the same diDeviceKey. See the description of dlDownloadKey for additional details.
The IMAGE value is used to specify the value of dlDownloadlmage.
The parameter value range is 1 to ‘N’, where ‘N’ is vendor specific.
Rather than specifying a decimal number, the PROMPT string specifies
that the user must be prompted for the value.
The DEVICE value is used to specify the value of dlDownloadDevice.
The parameter value range is 1 to ‘N’, where ‘N’ is vendor specific.
Rather than specifying a decimal number, the PROMPT string specifies
that the user must be prompted for the value.
The ability to record an error requires that dIDownloadErrorStatus be clear, hence zero length. The dlDownloadErrorStatus is cleared when dIDownloadControl is set to initiate(1) to begin a download. The hmsDownloadStatus trap is generated at the same time that dlDownloadErrorStatus is set internally to record an error. If an error has already been recorded, then subsequent errors are not recorded, and subsequent traps are dropped. Only one hmsDownloadStatus trap is to be pending at any one time. If the MAC TALK command is not used to retrieve traps, then it is possible to loose old traps. When the dlDownloadControl is set to initiate, a pending hmsDownloadStatus trap is to be dropped.ANSI SCTE 38-8 pdf download.
