LED Status Indicator
The Proximity BUS Reader contains a tri-colored (Red, Green and
Orange) software configurable LED array that can be used to specify
the status of the device.
Refer to the Eiris Software (V4.7.1 or higher) or the ELC Programmer
Software (V2.1 or higher) Configuration Guides for setup details.
By default, the Red LED is used to indicate the following device
trouble conditions:
o The reader is unregistered (flashes once/sec.)
o The reader has lost RS-485 communication (flashes once/sec.)
RS-485 Interface
The Proximity BUS Reader has one 2m/6.5ft, 6-wire AWG-26
power/data cable with a male RJ-11 connector (6P6C) for connecting
to the RS-485 Junction Box.
I/O Interface
The Proximity BUS Reader also has a 2m/6.5ft, 4-wire AWG-22 cable
with ends for connecting two inputs and one digital output.
Color Conductor Details
Black Ground
Red Digital Output
Green Input 1 (IN1)
White Input 2 (IN2)
IMPORTANT: BUS Exciters MUST BE powered-down while wiring the unit’s
I/Os and when connecting to the RS-485 BUS. This will prevent accidental
shorts/spikes to cause damage to the devices.
General Purpose Inputs
The Proximity BUS Reader have two general purpose inputs
designated IN1 and IN2. EOL supervision may be added to either
of these inputs to detect: Open, Close, Line Cut and Line Short
conditions using an End-of-Line Terminator (P/N: 5-IOX00001).
Recommended Cable: 22 AWG, unshielded/twisted pair.
Digital Output
The Proximity BUS Reader has one general purpose digital output,
which provides open-collector switching (up to 100mA, 28VDC).
Recommended Cable: 22 AWG, unshielded/twisted pair.
RS-485 BUS/Stub Topology
The RS-485 BUS MUST BE wired using a BUS/Stub topology where the BUS Master (a RF IP Reader or an ELC Controller) is connected
anywhere along the BUS. The topology supports data transmission between the BUS Master and up to 15 Elpas BUS Devices (such as RF or IR
Readers; LF Exciters primary & secondary), Elpas Display Panels and 6x6 I/O Modules using Elpas RS-485 Junction Boxes (P/N: 5-JBA00485).
IMPORTANT NOTE: Only 1 RF IP Reader/ELC Controller and up to 7 RF BUS Readers may coexist together on a single BUS.
200M/650Ft: Max. BUS length 10M/30Ft: Max. Stub length 100 Ohm Termination: Required each end of the BUS.
Recommended RS-485 Backbone Cable Type: CAT5 Solid (4x2x26AWG)
For Power: Use three-twisted pairs (six conductors) between RS-485 Junction Boxes
For Data: Use one-twisted pair (two conductors) between RS-485 Junction Boxes
