Series 275 Mini-Convectron Module with DeviceNet
Instruction Manual - 275563
4.2.3 Data Rate (Baud Rate) Switches
Set the Baud Rate switch taking into account the limits due to the length of the cable between the
DeviceNet controller and the Mini-Convectron Module. See Table 4-5.
4.2.4 MAC ID Address Switches
Use the address switches to set the media access control identifier (MAC ID), which the network
master uses to address the module. When the device powers up or is reset by the network, the device
firmware will read the address switch settings.
Specific address values range from 0 to 63.
• Set the switch labeled “MSD,” to a value of 0 to 6 for the most significant (first) digit.
• Set the switch labeled “LSD,” to a value of 0 to 9 for the least significant (second) digit.
If a valid address between 0 and 63 is set, and it differs from the current address stored in non-volatile
RAM (NVRAM), the new address will be saved in memory. If the data rate switch is set to the PGM
setting, the firmware will use the data rate that is stored in NVRAM.
Upon connection to the DeviceNet network, the module requests a duplicate address check.
• If another device on the network has the same address as the module, the module will not join
the network.
• If the address is unique, the module will join the network and the net status indicator will blink
green until a connection to the master node is established. The net status indicator will be solid
green when the connection is established.
