Breakout Module
The Breakout Module is an optional component to interconnect ZoneLogix™ PRO Branches using standard RJ-45
cabling. The Breakout Module enables additional innovative solutions such as parallel sections and left and/or right
spur connections.
A connection is typically made from a ZoneLogix™
PRO Zone Controller to the All Signals connector on
the left side of the Breakout Module. The
Handshaking Only connector (right side) is most often
used to connect two branches together to provide
object flow control by the ZoneLogix™ PRO.
The Serial Only port (bottom left side) can be
connected to the ZoneLogix™ PRO Branch Monitor or
where it is needed to separate sections of the Branch
to handle unique configurations. The discrete wiring
header (bottom right) provides access to the
Handshaking signals of the ZoneLogix™ PRO allowing
external object flow control.
The Breakout Module is essentially a signal splitter, that allows you to split, or ‘breakout’, the Handshaking and Serial
signals into separate connections.
7.1
Handshaking Functionality
The Handshaking is the zone-to-zone communications that is responsible for handling package flow. This is primarily
controlled by a Request/Permission model. Whether the Branch is going Forward or Reverse, these (4) signals control
the flow between Zone Controllers:
• (Forward [Fwd] or Reverse [Rev]) Request Output
o The zone is making a request … “Can you take my box?”
• (Forward [Fwd] or Reverse [Rev]) Request Input
o The zone is receiving the request … “Oh, I got a request to take a box! A zone is requesting
permission to send a box to me.”
• (Forward [Fwd] or Reverse [Rev]) Permission Output
o The zone is giving permission … “OK, I give you permission, now go ahead and send me your box!”
• (Forward [Fwd] or Reverse [Rev]) Permission Input
o The zone is receiving the permission … “I got permission to send my box! Here it is!”
NOTE: ‘Request Out’ points in the direction of flow
From the description above, you can see there are (2) inputs and (2) outputs per zone-to-zone connection. These I/O
are fixed, meaning that they are dedicated inputs and outputs in the hardware design. Therefore, they provide
different functionality depending upon the flow direction as shown below.
Zones numbered #5 and #4 are shown for clarity, since the Branch is enumerated with the Master being Zone #1, and
the EOB being the last zone in the Branch. The depiction below, shows (2) Standard zones in a Branch where the EOB
would be on the left end of the Branch, and the Master would be on the right.
