38 Data Communications Setup
The Advance Network Gateway (ANG_EN) monitors the "local" ADH bus
for messages with a "remote" destination address. The ANG_EN
determines if the message destination is "remote" by searching it's
Address Translation Table (ATT). If the destination address is located
remotely, the ANG_EN encapsulates the ADH message within the data
portion of an IP packet and sends the message out the Ethernet port.
The Address Translation Table (ATT) records all known units that reside
on the Advance Data Hiway (ADH). Each record within the ATT contains
an ADH Loop / Unit number and the IP address of the ANG_EN the unit
is directly connected to. The ATT records are automatically added or
updated each time an ADH broadcast is received. Each ANG_EN
broadcasts it's ATT every 10 minutes. This insures the data intgerity of
all ATT tables. An uninitalized ATT is automatically updated after 10
minutes by receiving ADH broadcasts and ANG_EN ATT broadcasts.
Only Advance analyzer units broadcast on a periodic basis so it may be
necessary to add other type units when a new ANG_EN is added. An
alternate method of updating the ATT is to force all ADH units to send a
power-up broadcast by pressing the reset button or cycling the power.
The following procedure assumes that the Windows Hyper Terminal pro-
gram residing on your PC has been configured, the ANG_EN is opera-
tional and the PC is connected to the ANG_EN.
