1.1.24. Upload File - ULD
This command configures the MacFi-se to send a file via YMODEM to another
controller or computer.
Syntax;
ULD
msgnumber
Where;
msgnumber
= 1 - 99.
Example;
ULD2<CR> initiates upload sequence for message 2. After command is
executed, an YMODEM transfer of the file should also be initiated on the
controller or computer.
1.2 Synchronization
The synchronization capabilities of the MacFi-se allow for 100 Sync Relay outputs
per message location. Sync Relay outputs may be programmed automatically or
manually. Sync pulses must be at least 100mS in duration and spaced at least
100mS apart.
1.3 Sync Relay
Three terminal pluggable connector.
Position 2 Sync Relay Output, Common
Position 3 Sync Relay Output, Form A, connects to position 2 when activated
1.3.1.
Sync In
Line level RCA input. This input contains an audio sensor which detects tones for
synchronization. During recording the system stores a 250mS sync pulse each time
a tone is detected. During playback, the Sync Relay output(normally open) will be
activated at the time the tone was detected.
1.3.2.
Manual Sync
Push button intended for manual or real time programming of the Sync Relay.
During recording the system stores a 250mS sync pulse each time a button press is
detected. During playback, the Sync Relay output(normally open) will be activated
at the time the button was pressed. When the system is idle, pressing and holding
the Manual Sync button will show the current baud rate on the Status Display.
1.3.3.
Sync Indicator
The Sync Indicator is an LED which will activate for each synchronization pulse.
This indicator will function during both automatic and manual modes of sync
programming as well as during playback.

MacFi-se ENHANCED FEATURES
The purpose of this manual is to document and explain the added features of the
MacFi-se. In brief, these features include RS-232 (Serial) control and Synchronization
Relay. These features also change some physical attributes of the original MacFi unit.
These physical changes include, a 3 position Euro style connector for serial
communications, a RCA type input for automated sync track encoding, a sync
pushbutton for manual sync track encoding. The sync track relay populates positions 2
and 3 of Connector 2, which were previously unused.
1.1
Serial Communication(RS-232)
1.1.1. Physical Connection and Protocol
Three terminal pluggable connector. The Serial Communication port operates at
9600 / 115,200 baud with 8 data bits, 1 stop bit and No parity. This port is
designed for communication with a local user or controller over a short reliable
interface. No error detection scheme is implemented over this interface. All
command characters and returned information are in ASCII format. When
connected properly, the system prompt MFI> will be returned.
Position 1 Receive
Position 2 Transmit
Position 3 Ground
1.1.2. Toggle Baud between 9,600 and 115,200
The MacFi-se supports two RS-232 (Serial) port speeds, 9600 and 115200 to
maintain compatibility with control systems and decrease file download times.
These rates are toggled by holding the Manual Sync button during power up.
1. Remove power from the system
2. Push and hold the Manual Sync button.
3. Reapply power to the system while holding the Manual Sync button. The
Status Display will show Lo or Hi or indicating the port speed of 9600 or
115200 respectively. Repeat the process to change the speed. To check the
current baud rate, press and hold the Manual Sync button and the speed will
show on the Status Display
1.1.3. Command List and Descriptions
At the MFI> prompt various commands may be issued to control record,
playback and other functions of the MacFi-se . Each command and associated
string must be followed by Carriage Return or <CR>.
