1.1
GENERAL
Introduction
The Frequency Select Handle provides the ability to select and display the operating frequency of
the receiver or transmitter on the Front Panel. Power is provided from a regulated +9.5 Vdc supply
and draws typically less than 4.0 mA in sleep mode.
1.2
Printed Circuit Board Numbering Convention
To ease troubleshooting and maintenance procedures, Daniels Electronics Limited has adopted a
printed circuit board (PCB) numbering convention in which the last two digits of the circuit board
number represent the circuit board version. For example:
• PCB number 43-912010 indicates circuit board version 1.0.
• PCB number 50002-02 indicates circuit board version 2.0.
All PCB's manufactured by Daniels Electronics are identified by one of the above conventions.
1.3
Performance Specifications
Temperature Range:
-30°C to +60°C. (Optional -40°C to +60°C)
Supply Voltage:
+9.5 Vdc,
Supply Current:
less 35 mA
less 4.0 mA standby mode.

THEORY OF OPERATION
2.1
General
The user interface consists of an 8 digit display and 3 pushbuttons, frequency increase Ø,
frequency decrease Œ, and options ¸. On power up or key press, the synthesizer is interrogated
for the current channel number and channel frequency. This information is used to generate the
display, and update the synthesizer itself.
The Frequency Select Handle communicates with the synthesizer using a standard 2 wire serial
interface (9600 Baud, 8 bits, no parity, 1 stop bit). The command protocols are simple ASCII,
both to and from the synthesizer. Another dedicated line allows the handle to temporarily wake up
the synthesizer if it has been powered down. (This is currently only used on the transmitters)
The Frequency Select Handle is built around a PIC microcontroller and is powered from regulated
9.5 Vdc.
2.2
Handle Operation.
1) On Power Up the following front panel indications will occur: (in order)
•
•
•
•
Daniels Banner ("Daniels Electronics Ltd") will scroll by.
The current Channel Number will be displayed (for about 2 sec).
The current Operating Frequency will be displayed ( for about 2 sec)
The display then does to sleep.
2) To display the Current Frequency:
a) Press either the Ø (Frequency increase) or Œ (Frequency decrease) buttons
This will display the current Channel Number (for about 2 sec), then the current frequency
(for about 3 sec) The display will then go back to sleep.
b) To keep the display awake, just press the Ø or Œ buttons again before the display has
gone back to sleep. This will display the frequency for another 2-3 sec.
3) To change the Programmable Channel operating frequency (channel 16 only)
a) Press either Ø or Œ buttons to wake up the display.
b) Then use Ø or Œ buttons to change the frequency. ( Note the buttons must be unlocked to
be used. See (4) below.

c) Both the Ø or Œ have two modes of operation.
i. Single press is for small changes. Single button presses corresponds to single channel
( 25 kHz) steps.
ii. Accelerated is for large steps. After 6 seconds of the button being pressed the
frequency will change by8 channels per step (200 kHz). After 9 seconds of the button
being pressed the frequency will change by 20 channels per step (500 kHz).
Note: The operating frequency is set to displayed value once the Ø or Œ buttons is released.
4) To Lock / Unlock the Buttons.
a) Press the ¸ button. The display will show the current lock status ("Locked" or
"Unlocked")
b) To lock the buttons, press the Ø button ( the display will then show "Locked")
c) To unlock the buttons, press the Πbutton (the display will then show "Unlocked")
Note: To display the current channel and frequency, the display must be allowed to go to sleep.

3.1
ALIGNMENT
General
Under normal circumstances no alignment is required to the Frequency Select Handle.
3.2
Repair Note
The Frequency Select Handle employs a high percentage of surface mount components, which
should not be removed or replaced using an ordinary soldering iron. Removal and replacement of
surface mount components should be performed only with specifically designed surface mount
rework and repair stations complete with Electro Static Dissipative (ESD) protection.
3.3
Recommended Test Equipment
• Power supply - Regulated +9.5 Vdc at 0.1 A. Phillips PM 2811
