5.2.1 Terminal Assignment of RS232

Pin 1: not assigned

Pin 2: TXD (transmit data)

Pin 3: RXD (receive data)

Pin 4: not assigned

Pin 5: GND (ground)

Pin 6: not assigned

Pin 7: not assigned

Pin 8: not assigned

5.2.2 Ethernet Terminal

The LAN terminal type RJ45 complies with the standard IEEE 802.3 (10 MBit).

5.2.3 External Power Adapter

Connect the delivered power adapter to the inlet (see (4) inlet for power adapter in Fig. 5 - 4).

The power supply is 7.5 V DC at a maximum of 3 A. As long as a power adapter is connected, the batteries

are not used.
