TRANSCEIVER
FREQUENCY SELECTION
ESTeem Models 95, 96, and 98 transceiver frequency and receiver
squelch settings are adjustable via software control from the
RS-232/422 communications port. The frequencies can be
programmed easily through the use of the ESTEEM UTILITY
PROGRAM (see instructions included with the disk) provided with
the equipment or it can be performed manually using the procedure
listed below.
On the Model 96 and 98 only, the transmitter and receiver
frequencies can be programmed to different operating frequencies if
desired.
To change the Model 95, 96, or 98 operating frequency manually
perform the following:
1. Call the factory to obtain the frequency select codes for your
operating frequency(s) or use the ESTeem Utility Program to
calculate the select codes.
2. Enter the ESTeem Command Mode and perform the following:
CMD: Help Radio <cr> This will list the radio parameters.
The following commands and their settings will be displayed:
CARBSY = Set at the factory.
FRACK = Set at the factory.
HDLC = Set at the factory.
LATFREQ = This command causes the frequency select
settings below to be latched into the transceiver
digital synthesizer.
SEL/A1 = Transmitter frequency select code.
SEL/A2 = Receiver frequency select code.
SEL/A3 = Receiver frequency select code (96 or 98 only).
SEL/N1 = Transmitter frequency select code.
SEL/N2 = Receiver frequency select code.
SEL/N3 = Receiver frequency select code (96 or 98 only).
SEL_SW1 = Receiver sensitivity select (0,1,2, or 3 level
settings. 0 = highest gain ).
NOTE: Model 96, or 98 only.
SEL_SW2 = Receiver sensitivity select (0,1,2, or 3 level
settings. 0 = highest gain ).
NOTE: Model 95 only.
TXDATA = Set at the factory.
TXFLAG = Set at the factory.
TXSTAT = Set at the factory.
3. Enter in your respective SEL Codes followed by a carriage
return.
Example: CMD: SEL/A1 = 22 <cr>
4. CMD: save <cr> To save the commands after you have
finished.
5. RESET the ESTeem to latch the frequencies or manually from
the Command Mode by performing the following:
CMD: LAT 1 <cr>
CMD: LAT 2 <cr>
CMD: LAT 3 <cr>
RECEIVER SQUELCH SELECTION
An application may arise where environmental noise triggers the
carrier detect circuitry and inhibits operation of the ESTeem. The
user has the option to increase receiver squelch above the noise.
Increasing the receiver squelch allows operation of the ESTeem in
the users' high noise environment.
REMEMBER, an increase in receiver squelch causes a
corresponding decrease in range.
The Model 95 receiver squelch is selectable via software from the
command mode. To change the receiver gain use the SEL_SW2
(0,1,2,3) command. 0 = highest gain setting.
The Model 96 receiver squelch is selectable via software from the
command mode. To change the receiver gain use the SEL_SW1
(0,1,2,3) command. 0 = highest gain setting.
