Welcome
Notes: In order for a panel to be a Master Node it must satisfy the following
conditions.
• It must be IP capable. Panels that are IP capable are usually
denoted by a “-A” at the end of their model names.
• If the panel is not a Touch Screen, it must have a TX3-IP IP
Module installed.
Figure 4 shows a Card Access System using an ethernet network with RS-485
subnetworks. The Card Access Controllers connecting to to a Master Node’s
RS-485 subnetwork are Slave Nodes to the Master Node. Each RS-485
subnetwork can have up to 63 controllers connected to it; you can still have more
than 63 Master Nodes connected to the ethernet network.
