BC9137

Abstract

BC9137 is a sign to select carts whose destination address is outside the range defined by 2 address.

Function

This sign is placed under the rail and reads the destination of all carts passing on it. If the destination address is strictly less than the address on line #3 or strictly more than the address on line #4, it activates a button or a lever placed on its left or its right. The signal can be used to trigger a rail intersection to extract the matching cart and send it to another track.

The comparison is made field by field with a final AND operation.

The BC9137 should not be used in standard routed network. It is provided for non routed networks, or non standard implementations.

Usage

BC9137 sign must be placed under a rail. At least a button or a lever (if anti-collision feature is used with BC9000) should be present on the left or on the right of the sign to command an intersection.

Syntax

Line #1 : Free

Line #2 : [BC9137]

Line #3 : first address of the range in the form XX.YY.ZZ

Line #4 : last address of the range in the form XX.YY.ZZ
