Cypress Suprex® RS-485 Series - Setup and Pre-installation
Final Field Installation Checklist:
• The Central unit and access control panel should have a common ground.
• The Remote unit and card reader should have a common ground.
• The RS-485 connection between the Central and Remote unit is straight through, and not reversed.
Unpacking:
Remove Central and Remote units from from
the packaging material and check interior for any shipping damage. Inventory
any included parts (depending on model) such as terminal connectors.
Bench Testing:
Before installing the units in the field they should be assembled and tested at a convenient bench top location. This will
make it easier to verify / change settings and check operation when both units are visible at the same time.
It is also a chance to become familiar with the system if this is the first time using the Suprex system. It is much more
difficult to set up and test the units when they are several thousand feet apart.
Both units will need to be connected with two conductors (see image below) and each will need to be powered by a suitable
power supply. For testing purposes, the units can share the same power supply.
Basic Bench Test:
During initial setup, refer to the Run / Configuration mode settings (pgs 7-9).
1. Connect a suitable power supply to both units. Each unit should be provided with 8 - 16 Volts dc and approx 300mA.
Units should be separated by a minimum of 24 inches.
2. Apply power. After about a 1-2 second delay both units Diagnostic LED should be flashing green. The supervision relay
(Relay 3) activates when the units are communicating. Note: Supervision relay is disabled by default (see pgs. 7-9).
3. Touch a jumper wire from the Ground connection to the Relay 1 input on the Central unit. Relay 1 on the Remote unit
should activate with an audible click.
4. Units are shipped from the factory set for the Wiegand data format. If a different format is required, set the DIP switch to
the required reader and panel format (see pgs. 7-9)
5. If a reader & panel are accessible, connect the reader to the Remote unit & the Central unit to the panel to verify card
reads are accepted by the access control system. If troubleshooting is necessary, it is easier with units in close proximity.
6. Once these steps are completed, the units are ready for installation at their permanent locations.
