Important: Notes On Grounding The B573 - Inncom B573 User Manual

When you first apply power to the B573, the following information will appear on the B573 LCD display:
1. First, the network MAC address programmed into the B573 will
appear for a few seconds. This is programmed at the factory.
2. Next, the Network IP Address and Subnet programmed into the
B573 will appear for a few seconds. The IP Address and Subnet can
easily be changed using the LCD display and buttons on the front of
the B573. This is covered in Section 1.4 on page 13.
3. Then, the B573 type and software version of the B573 will appear:
At this point, the B573 LCD display will remain displaying the B573 type and software version as shown in Step 3
above and the GREEN "DIAG" LED on the lower right of the B573 front panel will flash once/second UNTIL :
•
The desired IP Address and Subnet values are set into the B573 using the B573 LCD and front panel
buttons. This will be covered in Section 1.4 on page 13.
•
The "B573_MC.cfg" script file is created (or modified if it already exists ) to include the IP Address(s) of
any B573(s). This will be covered in Section 1.6 on page 16.
•
The "B573_MC.exe" (B573 Media Connector Software) is running and has connected to the B573(s).
When the "B573_MC.exe" program connects to the B573, the GREEN "DIAG" LED will begin to flash
twice / second. This will be covered Section 1.8 on page 19.

IMPORTANT: Notes on Grounding the B573

For communication reliability and equipment protection, the B573 must be connected to earth ground.
If the B573 has the optional 120/240VAC power supply installed, the AC power source that you connect the AC
line cord from the B573 to must have a valid earth ground connection. The ground pin on the "AC In" socket on
the rear of the B573 is physically connected to the B573 metal housing and to any "common" pins on any of the
connectors on the B573.
If powering the B573 with a 120/240 VAC to 12VDC power supply via the "DC Power" input jack on the bottom left
rear of the B573 , the power supply should internally bond its 12VDC Common output to the 120/240 VAC input
Earth ground connection. Any 120/240 VAC to 12VDC power supplies provided by Inncom (including P/N 04-
4040) will have the 12V DC output common internally connected to the Earth connection.
If using a 12VDC power supply that does NOT internally bond the 12VDC common to earth,
there is a marked Earth ground connection screw and lug on the upper left on the back of the
B573 that can be used to physically connect the B573 chassis to Earth ground.
