OPERATION BY COMPUTER
1. Connect appropriate cable from your computer to Control Unit's DB9 connector on rear panel.
2. Most computers have a ‘HYPER TERMINAL’ or equivalent capability. T o get into Hyper terminal click
on your computers ‘Start’ box and go to ‘Programs’. Then slide to ‘Accessories’ and then to
‘Communications’
Then slide over to “Hyper Terminal”
Double click on Hypertrm.exe (execute file)
The next screen is called “Connection Description”
It will ask you to enter a ‘Name’ (ie OR2800P) and choose and icon. Then click ‘OK’
The next screen says “Connect to”. Go to the last box and click on “Connect Using”. Choose direct to
‘Com 1’ and click ’OK’
The next screen will bring up your Port Settings as follows:
baud rate 9600
bits 8
stop bits 1
parity none
handshake present, but not used
Click ‘OK’ and your terminal is now set up and accessible from your desk top icon.
If computer control is desired and a program like NOVA or SKYMOON is used, their instructions cover
the interface to the RC2800PX. Logging programs like CT and others are compatible as well. If you are
using a program that currently does not work with the RC-2800PX, send the author of that program a
copy of this page and the following two pages regarding writing software.
HYPER TERMINAL OPERATION:
A. Commands in upper or lower case are acceptable.
B. All commands are followed by an ENTER (carriage return / cr).
C. Remote operation (Mode 1) is initiated automatically from the terminal. Once terminal is at-
tached to the RC-2800PX, TURN ON THE RC-2800PX. IF IT HAS BEEN ON, TURN IT OFF.
WAIT 5 SECONDS, AND TURN IT BACK ON. Display will look something like this:
M2AZ1 2.2 KO6YD The 2.2 is the version software and KO6YD is the author.
A=25.4 S=9 S Note: early units may not have the decimal point. S = top
speed setting and ‘S’ means the unit is stopped.
D. To go to a new heading say 180.5, type that number in and hit ‘enter’. The readout will stream
down the monitor during rotation. It will look something like this:
A=26.7 S=1 M (‘M’ indicates the rotator is moving)
A=32.8 S=3 M
A=37.3 S=6 M
A=45.2 S=9 M
and finally;
A=180.6 S=9 S
If you turn the unit off, the last message would be: A=180.6 ERR=05. ERR=05 means the unit
has saved all volatile data and is experiencing “Low 12 volts”. Other ERR messages can be
found in the ‘SOFTWARE PROGRAMMING’ section.
E. You can now increment (0.5 deg orless) quickly back and forth with no delay. Type + and
‘enter’ for CW or UP and – and ‘enter’ for CCW or DOWN. This feature is currently Keyboard en-
try only.
