Setting the I/O bus addresses
Setting the I/O bus addresses
Each EX2 on the link with the Tracer MP581 must have a unique address. Configure the address using the DIP switches on the EX2 circuit board (Figure 50). Table 23 shows the DIP switch settings for expansion modules 1 through 4.

Input/output terminal wiring
All input/output terminal wiring for the EX2 module must meet the fol- lowing requirements:
•All wiring must be in accordance with the National Electrical Code and local codes.
•Use only 18 AWG
•Binary output wiring must not exceed 20 ft (6.1 m) and must be in conduit.
•Binary input wiring must not exceed 20 ft (6.1 m) and must be in conduit.
•Analog and 24 Vdc output wiring distances depend on the specifica- tions of the receiving unit. Use shielding for analog and 24 Vdc outputs.
•Do not run input/output wires in the same wire bundle with
