Physical Description of the BMX NOC 0401 Module

Front

The front of the module presents the following features:

Rotary Switches

The back of the BMX NOC 0401 presents two rotary switches, which you can use to specify how the module will obtain its IP address.

The settings of these two rotary switches work together to specify the source of the module’s IP address, as follows:

Setting	Description
Upper switch:
0...9	Tens value (0, 10, 20...90) for the device name setting. It is added to the ones value on the lower switch to identify the module to a DHCP server.
A...F	Tens value (100, 200, 300...150) for the device name setting. It is added to the ones value on the lower switch to identify the module to a DHCP server.
Lower switch:
0...9	Ones value (0, 1, 2...9) for the device name setting. It is added to the tens value on the upper switch to identify the module to a DHCP server.
A + B	BootP1:The module obtains its IP address from a BootP server.
C + D	Stored1: The module uses the IP address configured in the application.
E + F	Clear IP1: The module applies its default IP address.
1. The lower switch alone determines module behavior. The upper switch is ignored.

Switch Labels

The right side of the module displays two labels explaining the choice of rotary switch settings, as depicted below.
