当组地址加载非零值时
将启用杂项操作说明组操作。根据NMRA标准，当组地址被启用时，DSD将不再解析发送到其主地址的速度/方向数据包。此外，DSD将忽略发送到其组地址的长格式CV访问指令。因为DSD指令解析器为组地址分配了更高的优先级，这在某些情况下可能会导致意外行为：当DSD设置为14速步模式且组地址处于活动状态时，DSD输出将不再响应发送到主地址的FL功能命令。这可以通过使用不同的速度步进模式或启用FL组成功能（见CV 22）来补救。如果组地址设置为与主地址相同的值，DSD将不再处理发送到主地址的长格式操作模式CV访问指令。因此，用户将需要使用服务模式CV访问指令来清除组地址。如果启用了扩展地址（请参阅CV 29），这将不是问题。
如果在14速步模式下使用解码器
FL位应清除为0。如果您使用的是28或128速度步进模式，则该位应设置为1。STE位必须设置为1才能启用使用CV 25选择的任何速度曲线。否则，DSD将提供线性（直线）油门响应。EAM位必须设置为1才能激活扩展地址功能。注意，一旦设置了该位，解码器将仅响应发送到扩展地址的命令，而发送到主地址的命令将被忽略。如果您使用的命令站不支持扩展寻址，并且该位意外设置，则可能会出现问题。在这种情况下，必须将DSD连接到编程轨道，才能访问CV并清除位。DSD不支持高级确认或备用功率转换，ACK和APS位将始终读取为0。
When the group address loads a non-zero value
Miscellaneous Action Description Group Actions will be enabled. According to the NMRA standard, when the group address is enabled, the DSD will no longer parse speed/direction packets sent to its primary address. In addition, DSDs ignore long format CV access instructions sent to their group addresses. Because the DSD instruction parser assigns a higher priority to the group address, this may lead to unexpected behavior in some cases: When the DSD is set to 14 step mode and the group address is active, the DSD output will no longer respond to the FL function command sent to the primary address. This can be remedied by using a different speed step mode or by enabling the FL composition function (see CV 22). If the group address is set to the same value as the primary address, the DSD will no longer process long format operation mode CV access instructions sent to the primary address. Therefore, the user will need to use the service mode CV access instruction to clear the group address. This is not a problem if extended addresses are enabled (see CV 29).
If the decoder is used in 14 step mode
FL bit should be cleared to 0. If you are using a 28 or 128 speed step mode, this bit should be set to 1. The STE bit must be set to 1 to enable any speed curve selected with CV 25. Otherwise, the DSD will provide a linear (linear) throttle response. The EAM bit must be set to 1 to activate the extended address feature. Note that once this bit is set, the decoder will only respond to commands sent to the extended address, while commands sent to the primary address will be ignored. If you are using a command station that does not support extended addressing and the bit is set unexpectedly, a problem may occur. In this case, the DSD must be connected to the programmed track in order to access the CV and clear the bit. DSD does not support advanced acknowledgment or standby power conversion, and the ACK and APS bits will always be read as 0.
