VEC-1613

RTTY, ASCII, CW, and WeFax

Computer Interface

General Information:

Congratulations on your purchase of the VEC-1613 RTTY, ASCII, CW, and
WeFax Computer Interface.

The VEC-1613 Computer Interface lets you use the powerful JVFAX and/or
HAMCOMM software to receive and decode many different types of digital data
communication signals, using your amateur transceiver. The VEC-1613
Computer Interface connects between your amateur transceiver or
communications receiver, and an IBM or compatible computer with a standard
RS-232C serial port.

The JVFAX software enables you to receive fabulous full-color FAX and Slow-
Scan Television images on your IBM or compatible computer. The JVFAX
software has features such as Image Viewing, Editing, Disk Storage, Auto­Receive, Auto-Save, an Automatic Tuning Control, and Auto-Sync. The JVFAX
Movie Mode creates slideshow movies, using the images you have received.

The HAMCOMM software lets you receive digital signals such as Baudot,

ASCII, AMTOR ARQ and FEC, SITOR Modes A and B, NAVTEX, SHIP and
SYNOP. The HAMCOMM also has innovative features built-in, such as a

Spectrum Analyzer and a Tuning Scope.

The JVFAX and/or HAMCOMM software is included with the VEC-1613
package. However, for further information on these pieces of software, please
refer to the software documentation. Any questions related to either piece of

software should be referred to the software authors, and not
VECTRONICS.

Installing the VEC-1613:

Installation of the VEC-1613 requires an open RS-232C serial port with a
MALE DB-25 connector. Installation is very simple and straight forward.
Please follow the steps given below to ensure a proper installation is done:

1. Set the POWER switches to both the computer and the monitor to their
OFF positions.

2. Plug the VEC-1613 into an open RS-232C serial port, terminated in a
male DB-25 connector.

3. Using a small flat-tipped screwdriver, secure the VEC-1613 to the serial
port. DO NOT over-tighten the screws!

4.

Insert the 3.5mm stereo plug into the EXTERNAL SPEAKER jack on
your amateur transceiver or communications receiver. This jack is
generally located on the rear panel of the radio.

Using the VEC-1613:

The VEC-1613 is very simple to use. However, you must use the JVFAX and/or
the HAMCOMM software. Below are the steps for the use of the VEC-1613:

1. Set the POWER switches of the computer and monitor to their ON

positions, and allow the computer to fully initialize.

2. Load and execute your JVFAX and/or HAMCOMM software. Please

refer to the software documentation for software setup and operation.

3. Following the software instructions, go to either the SSTV or FAX

receive screen. Tune your radio to either an SSTV or a FAX signal,
depending o n t he software being used .

Note

: If you are planning on using the VEC-1613 for RTTY, ASCII, CW, FAX,

and SSTV, you will need both the JVFAX and the HAMCOMM
software. Neither JVFAX or HAMCOMM performs in all modes. This
is why you need both pieces of software to operate RTTY, ASCII, CW,
FAX, and SSTV.

Serial Port Configuration:

The VEC-1613 comes configured for a DB-25 serial port. However, you can
adapt the VEC-1613 to a DB-9 serial port, using a DB-25 to DB-9 adapter.
TABLE 1 shows the pin configurations for the DB-25 and DB-9 ports and their
functions. Use this table as a reference when selecting or building a DB-25 to
DB-9 adapter.
