Switches
SW1 - Reset Switch
The reset switch starts a hardware and software reset of the CPU PCB. The SW2, SW3, and
SW4 switches are read when reset occurs (and at power up). This switch should be pressed
whenever switch settings are changed while the power is on.
SW2 - Address Switches
An address must be set up to identify the site controller. For most applications, the address of the
unit should be set to 1. This is applicable for all situations except when the unit is used along with
other site controllers in an on-line loop. If the unit is used in an on-line loop, the address acts as a
unique identifier for the site controller. Addressing should start at 1 and continue sequentially.
The physical wiring order does not have to correspond with the address order, that is the first unit
does not have to be address 1. The chart below gives the switch settings for the available
addresses. Once again, if the unit is not used in an on-line mode, the address should be set to 1.
