eDCM 330
Intelligent two door PoE+ Controller
• Intelligent two door controller
supporting 3rd party read heads
The eDCM 330 (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
eDCM 330 also combines Power over Ethernet Plus (PoE+) connectivity, which powers
all door furniture and two heavy duty maglocks via a single CAT 5e/6 network cable.
Featuring PoE+ connectivity, the eDCM 330 has the benefit of eliminating the need for
an external local mains power supply at the door. This is particularly beneficial where
local power is not readily available or where cabling must be kept to a minimum.
Using just a single Cat 5e/6 cable to power the door(s), the eDCM 330 unit can offer
significant cost savings.
Using a powerful 32bit processor, the eDCM 330 has a large internal database that
can store up to 200,000 cardholder records. This gives full off-line card validation
and decision making capability at the point of entry, when host communication is not
The eDCM 330 supports most third-party access control read heads conforming to the
physical Wiegand (data/data) interfaces, covering a range of technologies from RF
Proximity to Biometric devices.
The eDCM 330 supports two door configurations. It can either be configured for one
read head on each separate door, with optional Exit push buttons, or can be configured
to support two reader heads (an Entry/Exit configuration) for bi-directional control on
a single door.
• Support for two doors
• On-board 10/100 Mbps PoE+
Ethernet connectivity to power
the reader and doors via a single
CAT5e/6 cable– no local mains
power required
• Communicates directly with the
central AC2000 access control
• Database supports 200,000
cardholder records for off-line
card validation
• Reader communications via
standard Wiegand interfaces
• Eight supervised inputs (four
available per door
• Four outputs (2 per door)
• Self resetting fuses – saves
maintenance time
• Onboard LED provides visual
status information
• Dedicated tamper input
• Suitable for use with AC2000

Product Highlights
Control and power up to two doors via Power over Ethernet
Plus Technology
The eDCM 330 works in conjunction with a Midspan power
injector between the network and the door and sufficiently
powers door readers and two heavy duty maglocks via a single
CAT 5e/6 network cable. This eradicates the need for an extra
external power supply above the door.
Host Communications
The eDCM 330 has an on-board 10/100 Mbps Ethernet
allowing it to communicate directly with the AC2000 host
central system
Onboard card reading technologies
The eDCM 330 supports a wide range of head technologies
using the two available on-board Wiegand connections.
Supported card technologies include Wiegand 26bit, CEM
37bit, Mifare, Corporate 1000 and many more.
Offline card verification
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 offline mode. Operating in off-line mode the reader can hold up
to 200,000 cards and 8,000 transactions.
The PoE+ injector or mid span device supplies all the power for the
devices and locks required by two doors.
