POW-R-SWITCHES 1M, 1S
When position 3 is set to Down, the outlet will return to the state that it
was in prior to the power interruption. For example, if the outlet was OFF
before the power interruption, the outlet will still be OFF after power is
restored.
• Position 4: Reserved for future use.
NOTE
If you need to change DIP-switch settings later, it is not necessary
to power the module OFF in order for the new settings to take effect.
3.3 Linking the Modules
After you set addresses and set all of the modules’ SETUP switches, you can
install the link cabling. Run straight-through-pinned twisted-pair or flat-satin
cables between the Switches’ Link Ports to interlink the Pow-R-Switch 1M and
the Pow-R-Switches 1S as shown in Figure 3-1 below. (This system follows
the EIA RS-485 specification for multipoint connections.)
