Janus C4 485 Line Header
Installation Guide
Specication
The Janus C4 485 Line Header is an access control system controller for use with Janus C4 host software. It allows
the communication of other either Single Controllers (Part No: JC4-ADV-C2-SNG) or Multi Controllers (Part No: JC4-
ADV-C2-MLT) on a RS 485 communication line. The Janus C4 485 Line Header is connected to the IP network and
allows communication to the other controllers on the RS 485 line.
The 485 Line Header can be used with di󰀨erent power supplies: a 12V external power supply (up to 5A), or
POE/POE+. It has an integral case with built in optical tamper. The controller supports both IP and RS485 host
communications.

Power Options
Input Power
Power to the controller may be provided by one of:
12V 5A (60W max) = 2.1mm Circular Jack (centre pin
positive).
PoE (IEEE 802.3.af =12.95W max)
PoE+ (IEEE 802.3.at = 25.5W max)
If tted, the 4.2V Lithium Polymer Battery (during
power outage only)
It is the responsibility of the installer to ensure su󰀩cient
power is available for the system. When selecting the
most suitable power supply, you need to balance the
convenience of PoE against the total requirements.
Output Power
Power draw of the controller includes the following:
Single-Blade Controller Quiescent Power = 250 mA
max @ 12V (3.0W)
Battery Charging power (if tted, only while battery
depleted) = up to 167 mA max @ 12V (2.0W)
USB Power (future use, if tted) = 260mA max @ 12V
(3.1W)
Blade Power (Door Blade = 1.0 W, I/O Blade = 4.0W)

Notes
Status LED
The Controller Status LED can be monitored during
installation and set up. It is not visible when the case is
closed. The LED reports the controller state as follows:
Yellow medium ash O󰀨-line
Yellow fast ash Port connected, not online
Green medium ash On-line
Blue continuous Controller initialising
Blue medium ash Application initialising
Cyan fast ash Wants data download
White slow ash Firmware update in progress
White fast ash Data download in progress
Red continuous Conguration button pressed for
less than 5 seconds
Red fast ash Conguration button pressed for
more than 5 seconds
Red slow ash Error
Battery
The lithium polymer 6,000mAh battery may be used
to provide a battery back-up service. Using a battery
ensures continuing power to controller and all attached
devices during power outages. Note though that
all system data is retained in non-volatile memory
indenitely.
The battery operating time is heavily dependent on
loading but will typically be up to 2 hours.
During battery operation, the 12V internal supply is
reduced to 11V and the maximum permissible total
current draw for all external sources is 1.5A.
The time required to charge the battery from depleted
to full capacity is dependent on available power (for
example, it may take longer from POE than from a 5A
supply), external current draw and product temperature.
It may take over 24 hours.
Battery Safety Notice
The 485 Line Header battery electronics contain
multiple safety elements to protect against over-charge/
discharge, short-circuit, over-temperature etc. However,
the following warnings should be observed:
Only t the original battery module supplied by
Grosvenor Technology and use only in accordance
with this document.
Do not use module if battery appears deformed or
damaged.
Do not disassemble, crush, pierce or rupture the
battery.
Do not short circuit or reverse polarise the module
nor attempt to charge the battery except in the
controller.
Do not store at a temperature below -20°C (-4°F) or
above +60°C (+140°F).
Observe local regulations when disposing of the
Lithium-polymer battery.
Never dispose of the battery using heat or re.
Battery Service Life
A battery service life of 5 years is possible, although
this can be a󰀨ected by a number of factors including:
a prolonged period of storage prior to use, the number
of discharge/charge cycles and the battery operating/
charging temperature.
To initialize the 485 Line Header
To reload the application that shipped with the controller
and delete all data.
Press button while powered o󰀨 and then power on, or
press button before momentarily pressing Reset button.
Hold until LED goes amber and then ashes amber after
about 20 seconds, then release button.

RS485 conguration
RS485 Connections
Up to 6 Advance controllers (either Single or Multis) can
be daisy-chained together on a 485 line.
A 485 Line Header must be congured to use the 485
protocol.
Other linked controllers are congured as 485 only.
Note that the 485 Line Header doesn’t have to be at the
bus end, it can be anywhere. Fit a 120 ohm termination
resistor at either end of the RS485 bus:

Note that all Janus C4 485 controllers require an Ethernet
connection during the commissioning process.
Use Janus C4 Congurator to discover and bring the
controller online. Once set up as the correct type and with
the correct network settings, the Ethernet connection can
be disconnected from 485 controllers.
Updating Firmware
The Controller rmware cannot be updated over a 485
connection as the les are too large.
If a rmware update is required while the controller has
an IP connection the Update Firmware button will appear
within the Quick Start app, enabling the process to be
completed easily.
If a rmware update is needed subsequently, the rmware
can be updated locally using a USB stick. This is a FAT32
formatted USB stick with rmware/app les in a “rmware”
directory in the root directory.

Note that a controller’s current rmware version is shown
in the Diagnostics tab, when the Controller is selected in
the Congurator.
To update rmware
1. Open Janus C4 UI and select Navigation > Devices
2. On the Devices tab, choose Controller and Right-
click and select the Commands option
3. Click the option Arm
4. At this point, insert the supplied USB stick into the
controller.
Note: You must insert the USB stick within one hour of
selecting the Arm option. Note that no messages appear
in Janus C4 during this process.
5. While the rmware le is being downloaded, the
controller LED will show a slow white ash. When
it is complete the LED shows a fast red ash. At
this point you can remove the USB stick. If the USB
stick is removed before the process is complete, the
rmware will not be updated.
No messages are shown on the Janus C4 user interface.
