The only optional configuration parameter is that when using tracking, if the
tachometer type for the Client(s) is set to Constant Tach; the Clients will rely
on a speed message sent from the Controller eliminating the need to provide
a tachometer input to the clients.
The Controller always triggers the Client readers and it will properly
configure the trigger settings on the clients when connecting. It is
recommended that the trigger settings for Controller and Clients be set the
same.
It is NOT necessarily to set the Transmit delay or Transmit point to a different
value on the Clients, as is done using the “traditional master/slave”
architecture of other Accu-Sort readers. In an AXIOM multi-reader network,
bar codes are sent from the clients to the controller as soon as they are read.
Restrictions
ƒ
If a controller is configured with tracking enabled, all clients must also
have tracking enabled.
ƒ
All units must have the same bar code types enabled, in the same order.
ƒ
Clients do not transmit data messages through their serial or network
host ports.
Multi-Reader Network LED and Troubleshooting
NOTE:
The following LED functions are overridden if EtherNet/IP
communications are used. (See Chapter 4 .)
The main AXIOM diagnosis tool is the Network LED. An AXIOM controller
will FLASH the LED red once a second if it cannot locate the specified
number of Clients. When all connects are made, the Network LED becomes
a solid green.
For a client, the Network LED remains off until a Controller initiates a
connection. Once a connection is made, the LED becomes a solid green.
Network Administrator Information
All communications from a Controller to the Clients is done using TCP/IP
Multicasting. The default multicast IP address used is 239.255.0.x, where x
is called the Controller Group Number (value from 0 to 255). If multiple
Controller/Client Groups are on the same network, it is important that they be
assigned unique group numbers so that each group is using a unique
Multicast IP address.
It is important that the network be configured so that Multicast network traffic
will be transmitted between these readers. The AXIOM multicast messages
are configured with a Time-To-Live of 1, so they will not pass through a
router. Additionally, an Ethernet Switch which supports IGMP snooping may
be utilized to restrict the multi-cast traffic seen by the AXIOMs as well as any
other items on the same network.
All communications from the Clients back to the Controller uses standard
UDP messaging.
