transceiver. The cables from the RPI to computer and
transceiver are not included with the RPI and must be
ordered separately.
Programming Software
The following three types of programming can be
performed with 7243 portable transceivers:
Personality Programming - This programming sets the
parameters that can be different for each transceiver
such as channel frequencies, system and group infor-
mation, and locality information. This programming is
performed by the LTR-Net Programming software,
Part No. 023-9998-457, and described in Section 3 of
this manual.
Transceiver Tuning (PCTune) - Most transceiver
adjustments are made electronically and stored by the
logic. The software used to perform these adjustments
is called PCTune, and it is described in Section 5.
NOTE: To run the PCTune software, the transceiver
must first be re-flashed with temporary test operating
software (see following).
Loading Different Operating Code (PCFlash) - The
PCFlash software is used to upgrade the actual oper-
ating software of the transceiver. This software is
stored in a reprogrammable Flash memory device, and
is the basic operating code of the transceiver.
The LTR-Net operating software may be changed
to upgrade features, correct bugs, or tune the trans-
ceiver. Section 5.2 describes how temporary test oper-
ating code is loaded to tune the transceiver and LTR-
Net operating code is reloaded to restore normal oper-
ation. Test operating code is included on the PCTune
CD, and LTR-Net operating code is included on the
PCFlash CD (see Table 1-1).
