12-62-0000 VHF & UHF TRANSMITTER
Product Manual
Sea Air and land Communications Ltd, 10 Vanadium Place, Addington, Christchurch 8024, New Zealand January 2018
Product Overview
The 12-62 Series transmitters are available as VHF and UHF units, with user-programmable power
outputs ranging from 50 milliwatts to 4 watts and a high VSWR tolerance. Using programming
software, each model can be tuned across its full frequency range with no hardware adjustments.
They are capable of operating as NRZ or POCSAG transmitters. The built-in POCSAG encoder can
be enabled or disabled as required.
In addition to a direct/RS232 buffered serial port, an on-board USB port enhances the range of
applications to which the transmitter can be applied. Input / Output expansion is also possible via
an external RJ45 interface
The USB, RS232 ports can be used to initiate paging transmissions using the Salcom proprietary
protocol, or Telocator Alphanumeric Protocol (TAP) PG1 PET (Paging Entry Protocol). These ports
can be used concurrently making it possible to connect a telephone interface unit and still initiate
paging transmissions via the USB port, with the RF output being through a standard BNC
termination.
The unit supports 4 discrete inputs with a different pre-programmed message on high and/or low
transition, plus voltage detection messages on the power input, having programmable debounce
delay control. They may be used to initiate relay commands for remote control applications.
Provision to transmit a message more than once and variable time between transmissions are
catered for.
The 12-62 supports multiple message queuing, and will queue up to eight 240 character messages,
or as many smaller messages that will fit into the available memory buffer (up to 80). Pre-defined
input messages are limited to a maximum length of 40 characters which may be configured using
the Salcom programming software. Control via the USB or Serial port is achieved using ASCII
character commands.
A watchdog is available to initiate an action or transmit the state of selected inputs at a
programmable frequency.
The 12-62 can be configured to transmit a warning message when the power supply (battery)
goes below a user specified minimum level and above a user specified maximum level.
Configuration of the transmitter is performed via the USB port or the serial port using the Salcom
programming application which allows for the setting of all operational parameters.
The 12-62 is housed in an attractive, durable extruded aluminium case with provision on the base
plate for wall mounting.

Product Manual
Sea Air and land Communications Ltd, 10 Vanadium Place, Addington, Christchurch 8024, New Zealand January 2018
Product Features - Overview
The 12-62 comes with several features that make the 12-62 a versatile solution to your
communication needs. Key features are overviewed below, with more details of their use provided
later in this manual.
•Messaging: The 12-62 supports pager messaging and can transmit 3 types of POCSAG
message (alphanumeric transmissions, numeric transmissions and tone only transmissions),
with any one of 4 function levels.
•Store & forward: Can be configured to operate as a store & forward transmitter. This is when
a transmitter is designated as a source, and a receiver listens to the source relaying the
message to another transmitter for retransmission. Configurable as an optional feature.
•Low Power Mode: In Low Power Mode the 12-62 will consume approximately 17.5mA until
the interrupt line INT4 goes low which will wake the 12-62 up into its normal standby state
consuming 35mA.
•Duplicate Message Reject: when enabled a database of the last 20 messages sent is
maintained. All of the entries are progressively aged out. The age out time of entries in the
list can be set from 1-255 seconds. Configurable as an optional feature.
•Simulcast Modulation Delay: when enabled, allows the user to configure the transmission
delay for modulated data. This delay can be configured to be between 10uS and 2550uS.
•Over Temperature Cutout: If the transmitter operates for extended periods in a hot
environment, a protective thermal cutout may operate to reduce the output power to a
safe level. It will reset when the unit temperature has fallen to below 70 deg.
•Aerial Mismatch: when enabled, allows reporting when an aerial is disconnected or
damaged. If a problem is encountered along with error reporting the power is reduced to a
level that is not likely to damage the transmitter. The feature must be self-calibrated for
each installation before use.

Installation
Power Supply
The power supply is connected via PI, green power connector to +13.8 Volts DC and Ground. The
unit is protected against reversed supply connections. The power source must be reasonably noise
free.
Radiation Hazard: Important! To comply with FCC Controlled/Occupational Exposure Limits the
aerial must be positioned or mounted to operate at least 0.26 metres away from Operational Staff
and 0.57 metres away from the general public. Use only the aerial supplied.
Antenna Installation
It is recommended to site the aerial a few metres away from the unit to avoid the possibility of RF
feedback and causing potential problems with the transmitter operation. An external (outside)
aerial is preferable and will provide better radio coverage. A suitable antenna must be connected
to the unit via the BNC connector on the end plate of the unit. The aerial connection should
present a nominal load of 50Ω, with a VSWR of better that 1.8:1.
The Salcom unit is designed to operate reliably over large distances, however the actual distance
can vary depending on the type of location, obstructions, local radio interference and antenna
system used.
Powering-Up
External indicators consist of a power indicator GREEN LED, normally flashing ON once per second
to indicate healthy microcontroller operation.
After a debounce delay, the green LED will flash rapidly if the low supply detector is activated. The
RED LED will indicate when the unit is transmitting. A flashing RED LED indicates the unit cannot
transmit as either the synthesiser is out of lock, the 12-62 is critically hot or an internal fault has been
detected.

Programming
Preparing to Use the Programming Software
To change the field programmable options, the unit must be connected to a PC using Windows XP
or later, running the 12-62 PSD programming software, downloadable from Salcom’s website
http://www.salcom.com/media/software/Salcom-1262-PSD-v2109.msi
Note: The 12-62 must be powered during programming with a nominal +13.8V to the power
terminals.
Connection should be via either the
(preferred) USB port S8, using the supplied
USB to USB mini cable, or the standard
serial port S2 to a serial port on the PC i.e.
DB9 connector.
When connected to your PC using the
USB to USB mini cable a (virtual) com port
will be created for that connection on
your PC.
Note: To use the USB connector with older computers, a virtual COM port USB driver may be
required to be installed. To install the USB driver (CP210x_VCP_Win2K_XP_S2K3.exe), run the driver
installer, which can be downloaded for your operating system, from Silicon Laboratories:
https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers
Note: If you do not have a serial cable you can make one with the S2 connections as shown in the
section Connectors and Pin-outs in this document. Alternatively purchase a Salcom serial
programming cable, part number 12-45-0000.
Note: Using the standard serial port S2 with a serial to USB cable will not work due to the high
speed of the USB port in relation to the serial S2 connection of the 12-62.
