Average input current (active antenna AAN FK2 included):
1 A max
Stanby input current (antenna not active)
0,07 A
PC interface:
2 wire RS 232
Fuse:
1,6 A/250 V inert
Number of Inputs (galvanic disconnected):
1
Number of Outputs:
2
Reading time:
50ms using default settings
Reading error rate

2.4
Connection characteristics of the digital inputs
The reader is equipped with an galvanic disconnected digital input. The positive edge
causes a trigger signal. The input voltage is 24 V.
2.5
Connection characteristics of the relay outputs
Relay 24 V/1 A/1 change over switch
The switch conditions can be modified by software parameters.
2.6
Pin configuration of the RS 232 interface
Using the 9 pin Sub-D connector (i.e. for PC) make the following connections:
pin 1 of X3 with housing of sub-D connector (shielding)
pin 2 of X3 with pin 5 of sub-D connector (ground)
pin 3 of X3 with pin 2 of sub-D connector (transmitter line of the reader)
pin 4 of X3 with pin 3 of sub-D connector (receiver line of the reader)
Interface parameters: 19200 baud, 8N1
2.7
Antenna cable
cable type: see chapter. Maximum recommended cable length between antenna and reader box: 5m.
Other cable length are available on enquiry.
1
definiton of the reading error rate: The reader is set to the default values (i.e. NRD1, NID1, TOR5, MD2...). A transponder is located stationarily within the
optimal antenna field (signal level is at least 250mV above noise level). The reader is triggered 1,000,000 times using the GT command. The total number
of wrong readings is zero.
