Manual addendum to RT-21 - September 25, 2018
Overview:
The RT-21 Az-El controller consists of two RT-21 units with a shared power
supply and shared chassis. The unit features a pair of new OLED displays for
sharp, crisp viewing, two main RT-21 PCB each with their own RS232 port, USB
port, and 8 position terminal strip on the rear panel. When teamed with the free
GH Tracker software from the website, this unit provides a fully automatic,
hands-free controller for many different combinations of Az-El rotator schemes.

The lower board is configured for azimuth and uses the lower display, serial
connectors, and terminal strip. The upper board is configured for elevation and
uses the upper display, serial connectors, and terminal strip.
Compatibility:
The RT-21 Az-El is suitable for:
Yaesu G5400 Az-El units
Yaesu G5500 Az-El units
Alfa Spid Az-El units
M2 Az (OR28900) with MT1000, MT3000 units
Create Design Az and El rotators – (RC5, ERC)
Any combination of Azimuth and Elevation rotators that:
a. Both use AC or Both use DC motors – AND -
b. Both use rotators that are within the capabilities of a standard RT-21
(The RT-21 Az-El is compatible with the Prosistel Az El system as well. Please
contact us for information regarding this rotator.)
Examples of systems that cannot use an RT-21 Az-El. These types of systems
would require separate azimuth and elevation RT-21 controllers:
1. Azimuth using a Prop Pitch motor (with PWM speed control) cannot be
accommodated with the RT-21 Az-El because the Prop Pitch requires the
10 amp motor supply. The RT-21pp must be used for the Prop Pitch
azimuth rotator. (EXCEPTION – we can configure the azimuth side for
relay control without PWM speed control capability, and then utilize an RT-
21 Az-El as long as we match the relay voltage type (ac or dc) with your
choice of elevation rotators.)
2. Azimuth with A Yaesu G2800, and elevation of G550 cannot be
accommodated because the G2800 uses DC motor, while the G550 uses
an AC Motor.
The RT-21 Az-El is compatible with SETUP Utility version 2.1 and later.
