sDCM 300
Two Door Intelligent Serial Controller
• Support for two doors
The sDCM 300 (Door Control Module) is a low cost, two-door controller designed to
interface third-party read heads with the CEM range of access control systems.
The sDCM 300 communicates with the host system via RS485 communications to an
S9032/64 serial controller or by TCP/IP using the Ethernet Communications Module
(ECM). Using a powerful 32bit processor, the sDCM 300 gives full off-line validation and
decision making at the point of entry, even when host communication is not available.
The sDCM 300 supports most third-party access control read heads conforming to the
physical Wiegand/Mag Stripe (data/data) interfaces covering a range of technologies,
for example RF Proximity. Customised solutions are also available using two high speed
serial RS485/RS232 interfaces to support non-standard devices such as, read/write
smartcards and crypto modules.
The sDCM 300 supports two door configurations. It can either be configured for
two read heads on two separate doors, with optional Exit push buttons, or can be
configured to support an Entry/Exit configuration for bi-directional control on a
single door.
• RS485 host connection
• Structured database allows storage
of large amounts of cardholder
records for off-line card validation
• Reader communications via
standard Wiegand or Mag Stripe
• Eight Supervised inputs
(four available per door)
• Two Relays (normally opened or
normally closed)
• Self resetting fuses – saves
maintenance time
• Onboard LED - provides visual
• Dedicated Tamper input
• Suitable for use with AC2000 SE
(Standard Edition), AE (Airport
Edition), Lite (using an Ethernet
Communication Module – ECM),
& webEntry II Pro system

Product Highlights
Host Communications
The sDCM 300 utilises RS485 communications to
connect to the host controller, such as the CEM
S9032/64 controller. The ability to connect to
an Ethernet host controller is provided by using
the Ethernet Communications Module (ECM).
Onboard Card Reading Technologies
The sDCM 300 supports a wide range of head technologies
using the two available onboard Wiegand connections.
Supported card technologies including Wiegand 26bit, CEM
37bit, Mifare, Corporate 1000 and many more.
Off-line Card Validation
The card database is initially downloaded to the reader’s
memory from the host computer with subsequent changes
to card data automatically sent as updates. This ensures
that the reader has up-to-date card information when
operating in off-line mode. Operating in off-line mode the
reader can hold in excess of 200,000 cards.
Easy to Install
The sDCM 300 is designed to be extremely easy to install.
After connection to the host controller, configuration
can be quickly performed using the AC2000 or webEntry
workstation software, ensuring that the unit is up and
running in the shortest of time.
