Wiegand Gateway Installation

 

In order to avoid any confusion or misinterpretation the following document has been drawn up.  The primary objective of the dIn order to avoid any confusion or misinterpretation the following document has been drawn up.  The primary objective of the document is to establish standards that all installations comply with.

Standards allow for quicker installation time and faster fast turnaround on fault finding.  OneSpace  will sign off all completed installations based on the standards listed on this page.

Standard Installation Practice

The following are installation best practices that need to be followed.

  1. All devices are mounted at right angles using a spirit level

  2. All installed cables must be labelled at both sides of the cable

  3. All data cable connections must have 0.5mm white ferrule crimped connectors when connecting to the Wiegand gateway connectors

  4. RS485 – Mylar 4pair twisted – maximum total length of 500m

    1. Connect the RS485 cable to the downstream devices using the daisy chain method.

  5. Label the RS485 cable on each device with “From device” and “To” device.

  6. Wiegand – If required connect the Wiegand device, such as keypad reader, cable to the connector block as follows

    • ​​​​​​​Red – 12Vdc​​​​​​​

    • Black – GND

    • D0 - Green

    • D1 – White

    • Red LED – Brown

    • Green LED – Blue

    • Buzzer – Yellow​​​​​​​

  7. Wiegand Output power rating – 200ma

  8. RS485 – Cable Type/Colour Code – A – Yellow / B – Green

  9. Relay – Connection

    • Connect the output of the relay connectors to the boom gate trigger box with the white rip cord cable. If connecting the relay to a Mag Lock use an external relay timer board to drive the Mag Lock.

Note: Maximum Wiegand cable length is 20m.

Cable Run

The cable run is an important part of the installation.  To ensure long term stability of the location it is imperative that the integrity of the cable is a primary focus during installation.  

In particular, the following should be considered. 

  1. As far as possible the cable should be protected against direct contact with UV from the sun.

  2. The cable should have no friction points on its complete run. The cable should not be run over or near any physical feature that moves or is possibly prone to moving to avoid friction points over time.

  3. If there is a concern or questions relating to the integrity or location of the cable it must be re-run. The cost of a call out later far exceeds the cost of the re-run.

Wiring Requirements

  1. Only specified cable or a direct replacement from an alternative vendor must be used

  2. All cable ends must have the following:

    • Ferrules

    • Cable markers as per the assigned number for that cable

    • All unused cable must be cut away

  3. Where multiple cable cores are used for a single connection, the cables must be twisted together with a ferrule connecting both at the end.

Installation

Location

Near gate control box or Gooseneck on a suitable stable surface

Mounting

  • Open the IP 65 case and remove the component panel.

  • If not already done drill 4 x 6mm holes at each corner of the casing for the mounting screws.

  • Fasten the casing to the surface with suitable screws.

  • Re fit the component panel

  • Power – Connect the 12Vdc supply to the connector block from either the gate motor 12Vdc or a suitable independent 2 amp power pack

RS485 Configuration​​​​​​​

Jumper settings

There can be a Maximum of 8 x RS485 device settings

  • The Wiegand gateway has a bank of 3 x jumpers to set its RS485 device ID

  • Each Wiegand Gateway on a RS485 bus has its own unique ID / Address, see image to the right for reference.

Note : If there is only 2 x Wiegand gateways on the RS485 bus then they must be configured as device ID / Address  0 and 1. Similarly if there are 4 Wiegand gateways then they must be configured as device ID/ Address 0 to 3.  If one of them is configured higher than 3 then the controller will not pole that device.

As always the last device at the end of the RS485 bus must have a termination jumper installed. This is a single jumper on the PCB

LED Status

  • The 12V Power LED is next to the connector block and remains on

  • The on board status LED will flash when the RS485 pole is in service
