Packet Time-out Value

The time out period is computed in seconds as:

Time Out Period = CV11 X 10

A CV value of 0 disables the time out period and the locomotive will run indefinitely without
receiving another packet.

For all other values, the DSD maintains an internal timer which is reset every time the DSD
receives a valid broadcast address packet or other valid packet whose address matches its
primary address or, if enabled, the extended address or consist address.

In the event no valid packets are received within the prescribed time period, the DSD will bring
the locomotive to a stop at the rate set by CV 4 and CV 24. The state of the auxiliary function
outputs will remain unchanged.

Default value:

00
