EXP-2000 Expansion Modules allow additional readers to connect to the access control panel using a single Suprex®
RS-485 link. This is useful at door/gate locations with more than one card reader, such as in/out door readers or high/low
gate readers. The Suprex® RS-485 can accommodate a maximum of 8 readers with the use of 7 EXP-2000 Expansion
Modules. Each reader requires its own data port on the access control panel.
Before using EXP-2000 Expansion modules with the Suprex® system, it will be necessary to perform a short configuration
process. This process determines how many expansion modules will be used with the Suprex® system. Each Suprex®
link can support up to 7 expansion modules.
Operation Overview:
The EXP-2000 pair of units is connected to the Suprex® pair of units via an RS-485 connection. The EXP Central units
will be daisy-chained off the Suprex® Central RS-485 port (labeled
EXP+
and
EXP-
). The EXP Remote units will be
daisy-chained off the Suprex® Remote unit RS-485 port (also labeled
EXP+
and
EXP-
). The only link between the
reader/gate location and the panel will be the Suprex® link; in this case, the wired link.
The Suprex® and EXP-2000 Expansion Modules operate on an addressing scheme. The Suprex® pair is always address
0. The first EXP pair will be address 1, the second EXP pair will be address 2, etc. (see pgs. 7-9). When configuring the
Suprex® pair to work with the EXPs, the Central and Remote units must be told how many EXP pairs they will be working
with. The Central and Remote units of each EXP pair must be configured with their address numbers.
Setup Process
:
By default, Suprex® units are not configured to accommodate EXP-2000 expansion modules. To
reconfigure the Suprex® units, follow this process for both the Central and Remote units.
• The Suprex® Central and Remote units must be configured with the total number of EXP pairs being used.
• This is configured in the Run Mode settings and is controlled by DIP switches 6, 7, and 8.
• Change settings on both the Suprex® Central and Remote units, as shown on pgs 7-9.
• The EXP-2000 Expansion Module pairs need to be properly addressed with their address number.
• The EXP address is configured by using DIP switches 6, 7, and 8 on the EXP-2000 Central and Remote units.
• The first EXP pair will be address 1, the second EXP pair will be address 2, etc. (see pgs. 7-9).
• Set DIP Switch 8 on the EXP Central and Remote units to set to address 1.
• Set DIP Switch 7 on the EXP Central and Remote units to set to address 2.
• Connect the EXP Expansion Modules into the system as indicated in the wiring diagrams on pages 23 and 24.
Suprex® Operation with Expansion Modules:
Using EXP Expansion Modules does not change the normal
function of the Suprex®, with these exceptions:
• EXP Expansion Modules are compatible only with the Wiegand interface type (does not apply to Wiegand No Filter)
• If the Suprex® Supervision relay is enabled, the Supervision relay will deactivate (indicate alarm state) if the
communication link fails between the Suprex® pair or ANY of the the EXP pairs.
(To enable Supervision relay, see Run
Mode settings, pgs. 7-9.)
• LED Indicators with Suprex® Pair:
• Suprex® Central or Remote status LED is solid green in Run Mode: one or more of the connected EXP units is not
communicating properly. Ensure all EXP units are powered and correctly wired.
• EXP status LED is solid red: EXP unit is not properly communicating with the Suprex® unit. Ensure the Suprex® unit
is powered and wired correctly.
• EXP status LED is flashing green: EXP unit is properly communicating with the Suprex®.
• The EXP-2000 Central and Remote pair will be functionally similar to the standard Cypress SPX-1300 Suprex® system.
