Delta Lighting Controller (GE Lighting) DLC-G1212 (Rev 1.3) Installation & Application Guide
Network Topology
Delta’s GE Lighting Controllers are designed to be installed in a system of V3.22 controllers, and are fully
capable as peer-to-peer controllers on a BACnet MS/TP network as Subnet devices, typically with one
System device (DCU or otherwise).

LINKnet Notes:
1. Ensure you use the recommended
balanced cable.
2. Ensure the cable is installed as a
daisy-chain from one device to the
next. (1000' or 300m maximum).
3. Ensure you install MS/TP terminator
boards when you have more than 1 or
2 devices.
4. Depending on the controller, up to 12
devices are supported on a LINKnet
network, with limitations on how many
of these may have I/O. (Refer to
the Technical Reference Manual.)

Ethernet Note:
If the DCU or DSC has Ethernet capability, it may exist on an
Ethernet network with other controllers in the same building, on which
the ORCAview OWS could reside as well (instead of PTP).
PTP
MS/TP Notes:
1. Ensure you use the recommended balanced cable.
2. Ensure the cable is installed as a daisy-chain from one device to
the next (4,000' or 1220m maximum).
3. Ensure you install an MS/TP terminator board (TRM-768) on each
end of each MS/TP network.
4. The maximum nodes per MS/TP network is 50 without a repeater,
or up to 99 with at least one repeater (RPT-768).

Network Communications Setup
The GE Lighting Controller communicates on a BACnet MS/TP network at a default speed of 76,800 bps.
Refer to the
ORCAview Technical Reference Manual
for further detail on configuring the BACnet MS/TP
network or changing baud rates, etc.
