$DEP: - DEPendency Dependency is a way to allow the device to confirm both the correct device type, as well as a minimum firmware version required to utilize this configuration. In most cases sending in configuration strings with additional parameters (ala, new capabilities) that the present level of firmware, the device will simply ignore the extra parameters; and this might cause undesirable behavior. Beginning with firmware version 2.4.2, an optional $DEP may be used to allow the device to check to see if the firmware is able to support all configuration commands and parameters.
$DEP: <Version>, <Version> …
Version: (String) ‘ Version’ is in the same form as that reported out by $SST: and contains both the device type as well as a minimum release of firmware needed. Take care when declaring <version> as the format is well defined: mmmmxx.yy.zz
mmmm: a 4 character string containing the device type. Supported devices types are:
AREG: WS500 Alternator Regulator; OEM branded are also an AREG device.
DCDC: WS3000r DCDC Converter. OEM branded is also a DCDC device.
xx, yy, zz: Numeric values separated by two ‘.’ xx, yy, zz must be complete and numeric (No wide cards allowed). The device firmware must be equal to or greater than the defined xx, yy, xx
Examples of $DEP are:
WS500 Alternator Regulator, firmware must be 2.4.2 or above
AREG2.4.2
WS3000r DCDC Converter, firmware must be 2.4.3 or above.
DCDC2.4.3
$DEP: DCDC2.4.3, AREG2.4.2 @
