Medeco Hybrid User Guide
6 of 16
• 3-level low battery alarm (alarm condition may be reset using a Master
key or using the IR interface)
• Access Control system for controlling access based on user groups,
valid entry times/dates.
• Tamper monitoring feature with temporary reader disable
4.1 IR Communications
The Hybrid MCU contains an IR communications port that allows programming of
the unit with user keys, schedules, holidays etc. as well providing for the transfer
of audit transaction data from the Hybrid to a PDA device. The IR
communications are initiated by the presentation of the Master Key.
4.2 Master Key
The Master key is used to initiate IR communications with the Hybrid reader and
to reset it in certain alarm conditions, but will not open the lock. The Master key is
always the first key in the database. The master key may be any (4-byte)
number. Its parameters default to Group = 0, Start date = 0, and End date = 0.
By default, the first tag read by the Hybrid reader at installation will be stored as
the master key.
4.3 User Keys
User keys are used strictly to open the lock. Each user key contains a key ID that
is checked by the MCU upon presentation to determine if access is allowed.
4.4 Non Volatile Memory Configuration
The Hybrid MCU contains 32kBytes of shared nonvolatile memory used for
configuration information, key ID database, and transaction history. The
maximum number of audit events stored in the transaction history is derived from
the memory leftover after setting the number of user keys.
4.5 User Groups
The Hybrid MCU allows segmentation of user keys into groups. Groups allow
authorization of users to be day, date, and time dependent. There are a total of
10 possible group numbers (0-9).
• Group0, strictly speaking, is not a valid Group Code. It is reserved for the
Master Key and is assigned by the e-cylinder. If a User key has a group #
of 0 it will be rejected.
• Group1 is authorized 24hours/day 7 days a week. (Key Validation Date
checking still applies).
• Groups 2-9 can be given authorization within 4 separate time windows per
day of the week. In addition, each of the groups 2-9 has an associated
code that indicates whether or not Holidays, extended open periods or
closed periods are to be enabled for that group.
