The FF-800 represents some of the latest technology in microprocessor control systems. It features a
68HC711E2 microprocessor and has 160K of ROM, and 34K of non-volatile RAM.
This large on-board memory capability gives the FF-800 plenty of room for new features. The speech synthesizer is
a Texas Instruments TSP53C30 with a vocabulary of over 400 words. There are also several "control phrases" that allow
special messages (like time of day, temperature, digital voice tracks, etc...) to be interspersed with speech
synthesizer words. Try an Overview of FF-800 features for a closer look at some of the
operation of the FF-800. Other system features include:
- Digital potentiometers for control of receiver, transmitter, and courtesy tone levels.
The digital levels can be entered by a DTMF command, or through the serial
- 8 user programable courtesy tones . Each receiver can have a separate courtesy tone (as
assigned by the sysop). The tone generator features sine wave synthesis with two-
tone (chord) capability, attack and decay, and frequency sweep.
- 8 predefined courtesy tones.
- Voter interface logic -- for systems that utilize an external voter system -- allows
separate courtesy tone for each of up to 8 receivers in a voting system. The tone can
be selected by last active or most active voted receiver.
- Over 80 sysop programmable system and annunciator messages -- allows the sysop to
customize many of the controller responses. The various sysop definable responses
- 6 rotating ID "bulletins & 2 rotating "welcome" ID "bulletins
- 8 tail messages (rotating or individual)
- Auto Patch
- Auto Patch Disconnect
- Auto Dial
- Control Auto Patch up
- Individual messages for each of 10 Emergency Auto Dial codes
- Repeater Time-out message
- ...plus many more.
- Full featured autopatch with number readback supress, custom user defined hang-up
code, and redial capability. Control via phone, and reverse autopatch are also
supported. Phone line interface includes a "line busy" logic input and an off-hook
logic output for shared line environments. There are 4 autopatch prefixes, three of
which can be disabled by the sysop on demand. Each patch command has its own
sysop programmable annunciator message. The FF-800 autopatch features a Lock-
Out list to allow the sysop to restrict toll calls, calls to a specific exchange, or even
calls to a specific number.
- 250 slot auto dial memory, includes 10 emergency auto dial slots (each emergency slot
has a separate, sysop programmable annunciator message).
- Autopatch dial out prefix capability for phone systems that require a prefix code for
access to an outside line.
- Remote autopatch support allows the FF-800 to connect to a remote phone line via a full
or half duplex link.
- Sysop selectable DTMF cover tone modes. Four modes are allowed: 1) mute DTMF
digits with no cover tone. 2) individual tones; mute with beep after each DTMF
release. 3) continuous tones; mute with constant rate (1Hz) beeps as long as DTMF
tones are received; 4) no muting of cover tones.
- DTMF code log -- The FF-800 stores all valid DTMF digits into a special buffer that
can be viewed via the serial port. The buffer is a wrap-around type which will store
up to 200 of the last digits entered.
- 64 command macros -- these allow a series of commands to be executed with one
- 52 event scheduler -- schedule events by month, day (or day of week), and time. Events
are defined by programming a macro with the desired commands for each event.
- 6 repeater states that store timers, courtesy tone assignments, and other status
information. Sysop may recall any state on demand.
- 8 on-board and 8 external digital outputs that can be turned on and off, or pulsed. The
external outputs are captured off the synchronous serial bus using sysop supplied
shift register ICs .
- 20 sysop programmable system timer controls, including:
Tail delay -- sets minimum time between tail messages.
Repeater Time Out.
DTMF access activity time -- time of inactivity required for repeater to automatically
shut down when DTMF access mode is enabled.
ID time -- maximum time between IDs.
Courtesy delay -- delay between loss of signal and courtesy tone.
Hang time -- delay between courtesy tone and repeater drop
Auto patch time -- maximum time for a normal auto patch.
- 4 analog inputs for remote sensing temperature or voltage. Scaling and
configuration commands allow customization of the metering range
- 4 digital command inputs that can be configured to execute a different macro
command on rising and falling edges.
- 4 sysop definable receiver inputs, a local microphone input, a control receiver
input, and 4 transmitter outputs. TX/RX pairs can be defined as main, link, or
- RS-232 serial port that can accept commands from a terminal or modem.
Supports baud rates of 75 to 9600 baud.
- Synchronous serial expansion bus for adding advanced features such as
the FF-8070 Digital Voice Recorder, or the FF-899 advanced rig interface (IC901,
IC735, Yaesu CAT rigs, or Kenwood HF). Also supports shift-register capture of
BCD frequency data for controlling thumb-wheel type radios or the Doug Hall
RBI-1 Kenwood radio interface.
- over 60 sysop programmable access codes. Each user level command can have a 1 to 4
- Three level security access. Control and configuration commands are segregated into
separate security levels.
- Built-in paging functions for two-tone, five and six tone paging sequences. Also capable
of supporting CTCSS and DTMF paging.
- Personal ID Numbers for up to 200 users. Allows each user to have their own 4 digit security code for access to the FF-800. The sysop may configure specific commands to require a PIN number, or all commands may require the user's PIN.
