the RS422 streaming output port of the sat-nms LBRX-1MT:
double get_lbrx_level() {
unsigned char c;
unsigned val;
double level;
while (1) {
c = get_byte_from_lbrx();
if (c & 0x80) {
val = c & 0x7f;
c = get_byte_from_lbrx();
if ((c & 0x80)==0) {
val = (val << 7) | c;
return - (val / 100.0);
}
}
}
}
The diagram shown below illustrates the RS422 signal timing and the polarity of the signals at pins 1 and 9
of the M&C connector. To ensure a reliable communication through the RS422 interface, the receive side
should terminate the line with 120 Ohms.
3.4 Parameter list
The table below shows the complete (alphabetical) list of M&C parameters the beacon receiver knows. For
each parameter the valid range and a short description is given.
