Interfaces
The interfaces are:
1.
Mini-PCI-Socket
2.
Two Ethernet-Interfaces 10/100 MBit + auto MDI (auto crossover function)
3.
1 serial interface with 6 status lines
4.
1 x USB connection (data logging)
5.
Relay switch an optional an AUX input with optocoupler
The Ethernet ports have RJ45 plugs. Because of the auto MDI functionality the radio
modem can be attached to a HUB or the LAN port of a computer with standard patch
cables. The HG 76342-A recognizes the cable polarity and automatically connects the
right signal lines.
The serial port is connected via a 9 pin female D-SUB connector. The pin allocation
makes it possible to connect to a computer COM port with a 1 to 1 serial cable. The
exact pin allocation is shown in Table 1 on page 6 below. The radio modem can be
powered by a supply with a voltage between 10 — 72V. The typical power consumption
is 4.0 Watt.
