PERATION
There are only four steps required to communicate with the
QTERM-R55:

rate and data format
•
connect to your host transmit, receive and ground lines
•
apply power
•
download application to the QTERM-R55
1.1
Power-On Setup
The Power-On Setup menu is used to configure the
QTERM-R55’s display contrast, baud rate and data format.
This feature is also used to download new terminal firm-
ware and to download the BASIC program file to the termi-
nal. Normally, when power is applied to the unit, it will
perform a few self-diagnostics and then check for a missing
or bad program file. If the application file is bad or not
present, the terminal will enter a download mode. If the
program is present and uncorrupted, it is compiled and exe-
cuted. An existing program file may be replaced with
another one through the Power-On Setup routines. Alterna-
tively, when a program ends normally (or due to an error),
the QTERM-R55 will enter download mode.
To enter the Power-On Setup menu, follow these steps:
•
Connect the power supply to the QTERM-R55.
•
Hold down any three keys and apply power to the
QTERM-R55 (you do not need to connect the transmit
and receive lines). When the words POWER ON
SETUP (POS) appear on the screen, release the keys.
•
After a brief pause, a menu will appear. The asterisk
indicates the currently selected menu item.
•
The keys used for navigating the Power-On Setup
menus are located in the upper right corner of the key-
pad (Figure 1-1 shows key locations for the 40-key
keypad; the keys for the 24-key keypad are in similar
locations with respect to the upper right corner of the
keypad). The up arrow is hereafter referenced as the
POS Up key. The other marked keys are similarly
designated as POS Down, POS Left, POS Right and
POS Enter.
