C.1.5. Rotary Switch Configuration
Two rotary switches configure the DeviceNet MacID, and one rotary switch configures the baud rate. Use a small
screwdriver to change the switch settings. The NODE ADDRESS (MAC ID) rotary switches are shown in Figure 1, and
the DATA RATE rotary switch is shown Figure 2.

Use the NODE ADDRESS switches to select the DeviceNet MAC ID address. The valid range of addresses is 0 – 63. All
combinations above 63 set the device address to the last address the device was powered up at and allow software
configuration tools to modify the MAC ID address.
Rotary switch S1 (BAUD) is used to select the DeviceNet Baud Rate. The valid range of baud rates is 1 (125K), 2
(250K), 5 (500K), and P (programmable). All values P and above set the baud rate to the last baud rate the device was
powered up at and allow software configuration tools to modify the baud rate.
Factory default settings for the rotary switches are typically Address 63, 125K.

The DeviceNet Gateway provides support for three LEDs: Serial Status (Modbus Diagnostic), Network Status, and
Module Status. The LED on the right indicates the current Serial or Modbus Diagnostic status. The operation of
the Modbus LED is described in Table 1.
