Operation; Operating Leds - Sentry Sample Sequencer 6 Installation, Operation & Maintenance Manual

Jumpers and Addressing
All IO Boards in the Sequencer 6 have jumpers to indicate to the CPU which IO board they are. Each jumper position
presents 3 options to the board; connect top and middle pins, middle and bottom pins, or no connection. Together the
jumpers form an address for each IO board. It is important for all IO boards to be sequentially numbered. Analyzer 1
must be paired with IO board 1 which will contain the address 65. Figures below show the four jumpers on a sequencer
backplane and how they would be configured for the first two IO boards.
