3 GENERAL DESCRIPTION

(1)

HITAG product lines of our 125 kHz family. The contactless proximity read and write system that works with passive transponders is suitable for various applications. Inductive coupling helps you to achieve reading ranges up to 200 mm and the use of cryptography guarantees highest data security.

The HTRM440 provides you with a universal, cost-effective, small and complete reader module. It enables communication with the 125 kHz transponders HITAG 1 and HITAG 2.

Easy integration and application of the HTRM440 isdue to small size and uncomplicated interfaces.

is the nameof one of the universal and powerful

DESCRIPTION

D1 cathode 1 P these pins can be used to connect a power LED1 D1 anode 2 O D2 cathode 3 P these pins can be used to connect LED2 and LED3 which are driven by the D2 anode 4 O

output pins of the core module

D3 cathode 5 P D3 anode 6 O SW1 a 7 I these pins can be used as inputs for switch SW1 and SW2 and are internally SW1 b 8 GND

connected to pins 17 and 18 of the HITAG core module

SW2 a 9 I SW2 b 10 GND RX 11 I receiver input; this antenna signal input has to be connected to the input line of

the antenna

TX1 12 O transmitter output; this antenna signal output has to be connected to the

output line of the antenna

TX2 13 GND antenna ground; the ground line of the antenna has to be connected to this pin

Note

1. P = power supply pin, O = output pin, I = input pin and GND = ground supply pin.
