BC9128 - ShadowJonathan/ByteCart GitHub Wiki
Abstract
The BC9128 sign is a sign to select carts whose destination address matches one of the 128 consecutive address indicated by the BC9128 sign and send them on a subring. It must be used by pair, with another BC9128 used just before leaving the subring.
Function
This sign is placed under the rail and reads the destination of all carts passing on it. If the destination address matches exactly one of the address in the subnet on line #4 of the sign, it activates a button or a lever placed on its left or its right. The signal can be used to change a rail intersection to extract the matching cart and send it to a 128-station subnet track.
See Extended rings to have details about extended rings.
Usage
BC9128 sign must be placed under a rail. At least a lever should be present on the left or on the right of the sign to command an intersection. Another BC9128 must close the subnet.
