If an installation requires more than one DIN rail, connect the Communication Supply (CS) and Communication Data (CD) terminals from the P1 BIM to the same terminals on the first device of every additional DIN rail (a TX-I/O Power Supply or Bus Connection Module). TX-I/O Power Supplies and Bus Connection Modules include a second set of CS and CD contacts to simplify connection of additional DIN rails. -

Page 16: Inserting The Address Keys
TX-I/O Quick Start Inserting the Address Keys The TX-I/O address keys must be inserted, seated, and closed correctly in order to function. Remove the address key from the strip, and then insert as shown. TX-I/O Start Up See the TX-I/O Getting Started Guide (553-636) for start-up procedures once the TX-I/O modules are installed, addressed, and wired.
