4.2.2. Simple Standalone Mode
The CLK and DTA lines may operate either as inputs or
outputs. The function assigned to CLK or DTA line
automatically defines whether this line will operate as
output or input. If configured to be an output, the CLK or
DTA line operates as an open collector line capable to sink
up to 150 mA. Such a current is usually sufficient to drive
relay used for a door lock control. When necessary, both
lines (CLK and DTA) can be configured to the same output
function and connected together (shorted) for increased
output current (max. 300mA). IN1 and IN2 lines operate
always as programmable inputs. The built-in REL1 operates
as output only. Each I/O line can be configured to have one
of several available functions.
Note: If output is used to control door lock then it is
necessary to connect general purpose diode (e.g. 1N4007 in
parallel to prevent electric tensions. The diagram for
connection of the diode is shown on the last pages of this
manual.

5.1. USERS
When operating in standalone mode, the PRTxxMF reader can register up to 120 users, each with a
card and/or PIN (3-6 digits). Entry of a PIN code must be followed by the [#] which is required to
mark the end of the PIN. Users are registered with successive numbers (ID=0-119). The reader
prevents programming of the same identifier (card or PIN) more than once.
Note: In standalone mode reader uses full card code (40 bits).
The reader supports five types (classes) of users:
MASTER
INSTALLER
NORMAL
TOGGLE
TOGGLE LTD
