Rotary Switch
|
Numbers
|
Description
|
|---|---|---|
|
Upper switch
 |
0…9
|
Tens value for the device name (0, 10, 20, …, 90)
|
|
10(A)…15(F)
|
Tens value for the device name (100, 110, 120, …, 150)
|
|
|
Lower switch
 |
0…9
|
Ones value for the device name (0, 1, 2, …, 9)
|
|
DHCP
|
Set the lower rotary switch to one of its DHCP positions to perform a DHCP request that has a MAC address as Client Identify.
|
|
|
Stored
|
The lower rotary switch is set to STORED (default setting) to use the application’s configured parameters.
NOTE: When the Device Name is empty, MC80 will use MAC address to get IP address. |
|
|
Clear IP
|
The lower rotary switch is set to CLEAR IP to use the MAC-based default IP address.
The default IP address format is 10.10.x.x
|
|
|
Disabled
|
Set the switch to Disabled to disable communications.
|
|
|
Device Name Naming Rules
|
||
|
There are three components of the device name. The default device name of the module is:
BMK C80 20310 : BMK_20310_xxy
The numeric value between 00 and 159 is set on the rotary switches. (For the default device name, xx is the value of the upper rotary switch and y is the value of the lower rotary switch.)
For example: For a BMK C80 20310 module, values of 120 (12 x 10) and 6 (6 x 1) on the respective upper and lower rotary switches indicate a value of 126. The value is appended to the default device name (BMK_20310_xxy) to create the valid DHCP device name of BMK_20310_126.
