GRAVIMETRIC GATEWAY AND ETHERNET COMMUNICATIONS

occurs much faster and more reliably than error detection over a serial network where

the G2 software and the controllers are responsible for detecting error. The end result

is that the G2 Server and the controllers will always get successful data communication

at a faster rate.

• Speed - Ethernet enables the G2 software to communicate with multiple Maguire

controllers at the same time. Even though communications between the Ethernet to

Serial converter and the controller is limited to the serial baud rate (by default 1200),

the G2 Server can communicate to multiple Ethernet Serial Servers simultaneously,

thus multiple controllers at the same time. The result is an increase in communication

speed. With serial communications, the G2 software is limited to communications to

one blender at a time across the serial MLAN network.

• Flexibility -

Ethernet offers more options for configuring your network topography

yielding benefits such as: greater distances, greater number of blenders on a single

network and wireless options.

Using Ethernet for G2 Communications

General Requirements when using Ethernet (Wireless or Cabled)

• G2-SA –

The G2-SA is the black box that is included with a licensed G2 installation.

The “Black Box” typically is known as being a signal amplifier, but also doubles as the

security key for the G2 Server. This security key dictates the licensing features and

blender count purchased by the customer. The G2–SA is require in all licensed

installations and must be connected to an available COM port on the G2 Server PC,

even if the installation does not use serial as the means of communication to the

Maguire blenders.

• Blender I.D. –

The Maguire controllers must be assigned a unique ID number

between 1 and 254. This is done at the controller keypad of each controller using the

*66 function.

• G2 Server requires a NIC (Network Interface Card) –

If Ethernet is to be the

primary means of communications to the Maguire controllers, then the G2 Server PC

must have an installed network card and also have the TCP/IP protocol installed.

Note: The G2 Server must have a fixed I.P. address if G2 Clients will access the server

over the Ethernet network.

• Assigning I.P. Addresses –

The G2 Server uses the TCP/IP protocol to

communicate with Maguire controllers when Ethernet is the method of

communication. Therefore the I.P. address of the G2 Server, all Ethernet devices at

the controllers (Ethernet to Serial Converters or Wireless Serial Server depending on

your application), and all G2 Client PCs must be in the same subnet range to enable
