4 CHANNEL PROGRAMMING AND OPTION SELECTION
4 Channel Programming and Option Selection
Channel and tone frequency programming is most easily accomplished with RF
Technology Eclipse50 software. This software can be run on an IBM compatible PC
and can be used to calibrate a T50, R50, and PA50 as well as program channel
information. See the Eclipse 50 users manual for further information.
But the T50 also has its own stand-alone high level interface, which can be accessed
from a VT100 compatible terminal, or terminal emulator (such as HyperTerm which is
available as a standard accessory with Windows).
The pertinent aspects of this High Level Interface are described below.
4.1 Setting Options
Note that any text in italics, represents data output by the T50 firmware, rather than
command line data sent to the T50 firmware.
The T50, after powering up, will issue a command prompt of the form:
T50>
Via a terminal, or a terminal emulator, a user can type various commands in. The basic
command to read parameters is:
T50>
read par parameter_name
Where “parameter_name” is one of the following:
Parameter Name Parameter Function Default Value Parameter
Range
LOOP_GEN Generate a LOOP potential

PA_SET_FWD_PWR Output Power of the PA (see

REV_PWR_ALARM Sets the maximum level of
reverse power. At this level of
reverse power, forward power
is automatically decreased so
that this reverse power level is
never exceeded. It also sets
the ratio of forward power,
which if exceeded causes the
reverse power alarm condition
to be asserted
25.0 (% of
PA_SET_FWD_PWR)
25.0 (% of current
forward power)
