LAN & Reader Ports.
The Inception controller provides two RS485 communication ports:
•
The “LAN” port is used to connect LCD Terminals and the LAN Expansion Modules listed
under “Compatible Expansion Modules” in the ‘Accessories List’ section.
•
The “Reader” port is used to connect Inner Range SIFER Readers.
The installation requirements that apply to
the “LAN” and “Reader” ports are as follows:
1. Follow all relevant wiring rules and standards.
2. Connections from the RS485 port to the remote devices may be wired in
a “daisy-chain” or
“star” configuration, or a combination of both within the limits specified below.
3.
“A” & “B” connections are wired in parallel across the network using twisted pair cable.
4.
The “0V” connection must also be wired to every device.
5.
The “+” connection is also used if the device is a Module on the LAN that does not have a
local power supply (e.g. LCD Terminal) or if the device is a SIFER Reader on the Reader
port. The
“+” terminal from an RS485 port must not be used to power detectors, relays, etc.
6. Twisted-pair data cable must be used. Shielded, two-pair cable is recommended.
e.g. Alpha 2466C/6413, Belden 8723/9842, Electra EAS7202P, Garland MCP-2S, Tycab
DPF4702/DCK4702 & Olex JD2PS485A3.
7. Do not use the cable shield as the 0V connection. Shields should be terminated to a
protective earth or 0V at one end of the cable.
8. An Inner Range RS485 LAN/R
eader Surge Diverter (see ‘Accessories List’) installed at one
or more appropriate points on an RS485 network will provide additional system protection,
particularly on long runs of LAN cabling and on multi-building installations.
9. A Multimeter may be used to check that the LAN or Reader port will operate reliably.

the “Inception LAN Installation Guide” from the Inner Range website for details.
See
‘Additional Resources’ at the rear of this manual.
Additional installation requirements for the
“LAN” port:
A.
The LAN “+” connection used to power LCD Terminals, etc. can be derived from any
Module with a local power supply, or from a separate external power supply. However, do
not connect the
“+” of two power supply sources together. e.g. Controller LAN+, LAN+ from
a Module with local power supply or LAN+ from an Integriti 3A power supply.
B. When wiring the LAN to a Module powered by a local power supply, do not connect the
incoming LAN+ wire to the LAN+ connection on the Module.
C. If a LAN Module deriving its power from the LAN is a large distance from the LAN+ power
source (e.g. Controller), it may require a separate local battery-backed power supply &/or
heavier gauge cable. e.g. Approx 200m for an LCD Terminal; Approx. 25-50m for other
Module types.
See the
“Inception LAN Installation Guide” for details.
If a separate power
supply is used, do not c from the controller Reader port to the Module.
D. No module is to be more than 1500 metres cable length from the controller.
E. Total LAN cabling should not exceed 2000 metres. If the total amount of LAN cable will
exceed 2000 metr
es refer to the “Inception LAN Installation Guide” for further information.
F. Up to 99 Modules of each type may be connected up to a total of 250 Modules. Note that
the system capacities (see page 5) will limit the number of modules that may be utilized.
Additional installation requirements for the
“Reader” port:
I.
If a Reader is more than 100 metres cabling distance from the controller, it may require a
separate local battery-backed power supply &/or heavier gauge cable.
See the SIFER
Reader installation manual for details.
If a separate power supply is used, do not c
from the controller Reader port to the Reader.
II.
No Reader, even with an independent power supply, is to be more than 1000 metres cable
length from the controller.
III.
Total Reader cabling on a single RS485 Reader port should not exceed 1000 metres.
IV.
No more than 8 Readers may be connected.
