1.3 Warnings
The VHF/UHF paging transmitter must contain an external 2.5 Amp fuse in the wiring to the input
connector in order to provide the correct protection of the internal electronics. If the power is connected
the wrong way around or over voltage the product may fail, this will void the warranty.
Note: Warning Statements: User must keep 65cm distance from the RF radio device
OVERVIEW

2 Overview
2.1 Basic System Overview
The VHF/UHF Paging Transmitter is a highly integrated communications radio system that includes
Audio and Data paging capability. This product will open up new lines of unparalleled high speed reliable
data communications in hostile environments while ensuring quick easy field installation and operation.
The VHF/UHF is essentially a transmitter capable of emulating a voice and Pocsag systems. The units
can be configured for several types of standard link formats and speeds. The transmitter comes from the
factory pre-configured.
The Transmitter unit maybe connected a PC, laptop or any RS-232 terminal, to display the menus and
control the operation of the Device. In operation the Transmitter maybe connected to any RS-232 device.
An external simple computer headset can be wired directly to the input connector for complete voice
functionality.
The VHF/UHF provides a menu system through the RS232 port of the Device. The menu configuration
utility is enabled by connecting to the device with a terminal program and typing the command
“MENU<cr>”, or the Hayes control command “AT?<cr>”.
The operational baud rate is configured using the menu system, the baud rate is only valid for the RS232
menu commands and system control commands. Once the option is chosen from the menu, it will not take
effect until the command Submit is used to change and save the current configuration. The menu
configuration utility will operate at the units pre-configured baud rate.

OVERVIEW
2.2 Display Modes
The Paging transmitter display contains a dual colour LED display indicator. This indicator provides a
complete picture of the operation and status of the Paging transmitter system, at a glance a technician can use
this to find problems in the field.
In standard standby mode the LED will blink green at one second intervals.
When the transmitter is activated the LED will remain on in a green steady state condition.
When digital data is presented into the data interface the LED will blink fast from red to green, this will
indicated changing data on the interface port.
When a PC is connected the and RS232 data is moving in and out of the unit then the LED will also fast
blink from one colour to another.
If the LED remains on constant RED then the system has developed a fault or recognised a fault condition,
the status display in the menu will indicated the type of fault, unless the fault is a intermittent one. Faults of
this nature are typically like low power supply voltage that dips when the transmitter is under full operation
and the voltage cannot be sustained.

QUICK INSTALL GUIDE

3 Quick Install Guide
3.1 VHF/UHF Transmitter Unit
The Transmitter is set at the factory to standard configurations.
The transmitters are shipped from the factory with the second lowest power setting, so that the units may
operate in close proximity to each other and with simple whip antenna for testing purposes.
3.2 Step by Step Testing
• First read the Introduction and Quick Install Guide section.
• Ensure the correct wiring connection as per the DIAGRAM section of the manual
• Connect the antenna to the BNC socket on the Radio Modem
• Power the units and check that the display LED’s indicate power and standby modes DISPLAY
MODES section of the manual
• Connect the test transmitter a RS232 terminal device at 19200,8,N,1 communications settings
• Type the command AT<cr> and check the Radio Modem responds with “OK”.
• Use the command AT?<cr> or MENU<cr> to connect into the menu system.
• Use a test pager with a cap code of 8 and set the transmitter to match the channel and frequency of
this device.
• Use the Diagnostic menu section to send a test page to the test pager.
• If the test page is received a full RF and data test transmission has now been performed.
The unit may now be configured to suit the required application this may include possible modification of
the following settings.
• RS232 Interface settings
• RF power levels
• Data and POCSAG control Inversions
• Frequency and channel selection and control
• Audio/Data mode control phase on hardware connector

MENU SYSTEM
4
4 Menu System
The VHF/UHF Transmitter contains its own internal menu system accessed with any general terminal
package. The Transmitter allows you to change several parameters to optimise its performance for your
particular application. All adjustments are made through a menu system, which is the user interface
programmed into each transmitter. A standard terminal program can be used to access the menu system,
which eliminates the need for set-up diskettes, DIP-switch settings, or custom software. Laptop
computers or Palm top systems are best suited for this operation in the field.
The set-up program is invoked by connecting the transmitter to any terminal program, setting the baud
rate for that terminal to 19200, 8, N, 1.. While any terminal which can be set to 19200 baud will work, all
examples for this manual were generated using the Hyper-terminal terminal program available from the
Website (www.hilgraeve.com) and comes standard with most windows installations.
When the set-up Menu program is invoked from the main menu screen for the set-up program will come
up on the Terminal screen as shown below. The user can select various options from the menu, such as
changing the transmitter power. The changes made to the operation of the transmitter are stored in nonvolatile memory to maintain the latest configuration even with loss of power.
NOTE: Users not familiar with this type of system should gain additional help.

MENU SYSTEM
4.1 Menu Navigation
The menu system contains a level indicator, which shows the depth that the current menu is away from
the master level. The indicator is on the first line on the top left most point as the example below. The
Indicator will be activated once the menu system is away from the MAIN MENU screen. The example
below is shown after the ‘P’ for Radio Personality is selected.
(1)--- Radio Personality Menu ---
Unit Name : Commtech W
Menu Time Out is 05 Minutes
(U) Set Unit Name
(T) Set Current Time
(M) Set Menu Time out
(Esc) Previous Menu
Enter Choice :
Commands are terminated by either entering the correct data with the correct amount of characters or by
hitting the ENTER KEY. Sub menu selection only requires a single key press to enter the sub menu
sections. The ESC key can be used at any time to terminate functions. Menus are reversed, or backed out
by using the ESC key, until the main menu area is reached then the question will be asked:
Are You Sure (Y/N)
If the answer is Y, then the system will return to the command prompt stage and if NO, the Main Menu
will appear again. The Menu system also contains and automatic timer that will reverse the user out of the
menu system after the programmed time. The time is measured from the last active menu display, and the
time is programmed from the Personality Menu area. The factory back out default time is 5 minutes. With
this automatic back out the menu system can be left in any state without any concerns of the system
operating correctly once the menu has exited, this prevents field technicians leaving site just to find out
that the transmitter has been left in the wrong mode.
