2008M NSL UNIT CONFIGURATION
Most of the 2008M NSL Units settings are actually set by the 2001 Lobby Unit Configuration. One item that is separately set is
the NSL Unit’s ID and RS-485 Communications Speed. These are set by the DIP Switches on the NSL Unit’s Controller
Board. There is an eight position DIP Switch numbered SW2 on the Board located just above the ON/OFF Switch SW1. The
individual switches are numbered 1 to 8 from the top to the bottom, and are marked as either ON-OFF, or Closed-Open. The
first five switches set the ID ...

NOTE: DIP Switches 6 and Switch 7 are NOT used.
Every NSL Unit in a given TAS-2000 System requires a unique ID. These should be assigned starting from “1" and
going up. Unit IDs must not be duplicated. For example if there are two Lobby Units in a system and they have
been given address 1 and 2, then those addresses are not available for the NSL Units.
The remaining DIP Switch, Switch 8, defines the NSL Unit’s RS-485 Communications Speed. This Switch 8 is
left in the “OFF” position for 2400 Baud.
