Page 5: About This Manual
Visikey Management Software Nexus controllers are designed to operate with and be administered from, Morley’s Visikey Access Management software package. Visikey is a powerful and flexible software package operating on a wide range of Windows platforms. Copyright © 2002 Morley Electronics...
Page 6: Forward/Backward System Compatibility
Forward/Backward System Compatibility Nexus controllers are fully compatible with existing Visikey (ACS) systems and can be installed alongside existing Morley ISC4 controllers. Nexus will also run the advanced communications networks sometimes required, such as IEC or Echelon protocols. When retrofitting existing installations it is important to ensure that Visikey version 2.40 or later is installed for correct...

IP ratings, resistance to abuse and operational temperature ranges are chosen. Morley offers a complete range of readers for all applications and user requirements; including vandal resistant and door entry panel mount readers and can be contacted for further information and advice.

These checks are the configuration and access rights for the user and may include the following considerations: • Does the card number on the card match a card in the database? Copyright © 2002 Morley Electronics Page 8 of 49 Document Number CTD1000...
Page 9 A PC administers the databases held in each of the controllers in the system controller network. Morley’s Visikey software package has been designed by Morley specifically for this task and has, over several years of use and development, become one of the most powerful and flexible packages of its kind available throughout the access control industry.
Page 10: Nexus Parts & Operation
Nexus Terminals & LED’s Nexus is designed with the engineer in mind. Therefore every reader input, contact input, relay output and communications connection is backed by visual LED confirmation of operation. Copyright © 2002 Morley Electronics Page 10 of 49 Document Number CTD1000...
Page 11: Nexus Power
The section ‘Applying Power’ (page 41), discusses power requirements in greater detail, as well as offering guidance on the estimation of system power requirements. Copyright © 2002 Morley Electronics Page 11 of 49 Document Number CTD1000...

When switching inductive loads it is important that adequate transient suppression is installed. Morley includes in the Nexus kit, Metal Oxide Varistors (MOV) that are used to prevent back e.m.f. These effects are also known, as ‘spikes’ and the MOV will help avoid damage to the Nexus controller. The MOV suppression kits included with the controller for lock suppression should be installed as close to the lock as possible.

Note however, that the connection length should not exceed 11m. Additional controllers will necessitate changing the RS232 connection to an alternate network structure, such as RS485 or Echelon.

PC. This is by far the easiest and safest way to connect the network to the administration PC. The converters are sent from Morley complete with housings and RS232 connection cables to the PC. Locate the converter as close as possible to the PC.

Page 19: Morley Free Topolgy Repeaters
In the event that limits on physical cable length or number of nodes are exceeded, a physical layer repeater can be use to interconnect 2 or more network segments. The Morley physical layer repeater can interconnect 2 to 6 network segments. The following drawing is a typical channel illustration utilizing a physical layer repeater.

All comms modules are designed to operate without the need for installer modifications. For further details on particular types used and for status checks, please call Morley Electronics. Nexus Controller Fuses Two fuses located on the processor module provide power protection for the Nexus controller.

Switch 8 is used to clear the controller RAM on power up. As controllers are tested at Morley prior to being sent out, setting the switch to ‘off’ prior to being commissioned, would cause the controller to attempt to re-use the test data, thereby causing controller malfunction.

Page 33: Reader Connections In Nexus
HID Proximity Readers HID proximity readers are available with both Wiegand and track 2 interfaces, however readers from Morley are supplied with a Wiegand interface as standard. All readers in the HID range are fully supported by Nexus. The diagram below shows typical wiring for ProxPoint, MiniProx, ProxPro, and VandalProx and PanelProx readers.
Page 34: Motorola/Indala Readers
Nexus controllers support all MR Sensors Track 2 readers, however some keypad versions need modification for correct LED operation. We advise customers wishing to utilise card and keypad versions to contact Morley Electronics before purchasing readers. The diagram below shows standard interconnection wiring for a 5132B magstripe reader.

Fitting Echelon Transceivers and Networks The installation and fitting of Echelon networks and transceivers is a specialist task, which should be carried out in conjunction with Morley Technical Support. For details of Echelon networks and cabling, please see the Echelon network overview earlier in this manual, or contact Morley Electronics.
Page 41: Applying Power
Nexus micro controller. Nexus does not carry an on-board power supply and is therefore reliant upon outside power to provide the necessary supply. Morley recommends that a (Part No. 109002) 1.5A psu be purchased for each Nexus controller. This rating is enough to power a fully loaded (i.e.
