Figure 22 A Network With Both Ends Terminated By Aperio Hubs - Mircom TX3 Series Installation And Operation Manual

In Figure 22, Aperio hubs are on both ends of the network. Note that the Aperio
hubs on the ends are terminated (DIP switch 8 is on) and that jumpers JW1 and
JW2 on the MD-1113 Module board are open.

Figure 22. A network with both ends terminated by Aperio hubs
Each Aperio hub must have a unique RS-485 network address. Set the
address using DIP switches A0-A3 on S101. See "Setting the Aperio hub
address" on page 33.
The RS-485 bus for the Aperio hubs must connect to the RS-485
connector on MD-1113 Module board.
The Aperio hubs must be connected in a daisy chain configuration (see
Figures 21 and 22).
When connecting an Aperio hub to the MD-1113 Module board:
• connect the A terminal on the J100 connector of the hub to the
positive (+) terminal of the RS-485 connector on the MD-1113;
• connect the B terminal on the J100 connector of the hub to the
negative (-) terminal of the RS-485 connector on MD-1113.
When connecting two Aperio hubs together:
• connect the A terminal on the first hub to the A terminal on the
second hub;
• connect the B terminal on the first hub to the B terminal on the
second hub.
Aperio hubs located on the ends of the RS-485 network must be
terminated. To terminate an Aperio hub, set DIP switch 8 (TERM) on
S101 to ON (see Figures 21 and 22).
