Nesis III — Installation Manual

10.3

Connection Details

Radio Trig

the port is connected with a Trig TY91/TY92 radios. Trig’s

slightly modified SL40 protocol adapted for 8.33 kHz channel spacing
will be used for communication.

Flarm compatible device

the port is connected with a Power Flarm, TRX

1500, or some other Flarm compatible device. Automatic baud rate
detection is used for Flarm devices. Nesis expects one of the following
baud rates: 4800, 9600, 19200, 28800, 38400, 57600. We recommend
using higher boud rates like 38400 or 57600, when possible.

NMEA GPS out, 4800

the port will send out GPS data in NMEA format at

4800 baud, N-8-1

5

. RMC, GGA and GSA sentences are sent every

second.

NMEA GPS out, 9600

same as above, but at 9600 baud.

NMEA GPS out, 19200

same as above, but at 19200 baud.

Connection Details

Next sub-sections illustrate connection details for specific devices. These are
merely our recommendations.

Some devices can be connected in different ways. Any device manual always
supersedes instructions given here.

10.3.1

TQ KRT2 Radio

Please read the

KRT2 Manual

before any connection is made to Nesis. The

manual can be obtained from

https://www.tq-general-aviation.com

.

Connection to a KRT2 radio is made using a trick. Nesis pretends to be a
KRT2RC remote control unit. This means that connection is only possible
when the remote unit is not connected to KRT2.

KRT2 utilizes 15 pin D-SUB connector, where the housing is used as 16-th pin
for GND. Figure 35 illustrates the connection of KRT2 and Nesis. Illustration
shows only leads required by Nesis. Much more leads are connected to the
15 D-SUB connector. Use an adapter board, if possible. Please refer to the
KRT2 documentation for more details on connections and adapter board.

If KRT2 and Nesis are both connected to the same airplane ground, then
GND line between be omitted (dashed line).

5

N-8-1 – no parity, 8 bit data, one stop bit.
