Serial Thru /MIDI switches
. With these switches the Mac Syncman
MIDI interface can be bypassed so that the Mac can be routed direct-
ly to the printer or modem without having to re-plug serial cables.
There are two Thru switches - one each for the modem and printer
port. When either of these switches is In, the port becomes a MIDI
port. When either switch is Out, the port is routed directly to the
modem or printer. Note: The MIDI indicator lights will only func-
tion when these switches are In. These switches will normally be in
when using your sequencer and out when using your printer or
modem.

Routing Switch.
The Mac Syncman can be configured as either a
dual 1 In /3 Out or as a single 1 In /6 Out MIDI interface. To config-
ure the unit as a 1 In /6 Out interface using the Mac printer port, set
this switch to the right position. To configure the unit as a 1 In /6
Out interface using the Mac modem port, set this switch to the left
position. To configure the unit as a dual 1 In /3 Out interface using
both the modem and printer port, set this switch to the center posi-
tion. The most common configuration is the dual 1 In /3 Out setting
(i.e. the center position).
3.
MIDI In/Out Indicator LED’s
. The Indicator LED’s will light when-
ever the Serial Thru switches are in and MIDI data is sent or
received at the corresponding MIDI port. For example, if your mas-
ter keyboard MIDI Out is connected to the Mac Syncman front panel
MIDI In (which is the modem input) and you play your keyboard,
the Modem In LED will flicker.

Dip-switch Group
. Provides control of various Mac Syncman func-
tions described in detail below.
5.
Tape Sync Read/Write Indicator Light
. This LED will light when
either Mac Syncman is in Write mode and a sync stripe is being writ-
ten to tape, or when Mac Syncman is in Read mode and a pre-
recorded sync stripe is being read from tape.
6.
Write (to Tape) Switch
. When first pressed the Tape Indicator Light
will light and Mac Syncman will output the selected type of sync
tone for recording to tape. When this switch is pressed again, the
Read/Write Indicator LED will go off, and Mac Syncman will be
taken out of Write mode.
If you are striping SMPTE to tape the Write Switch has another use-
ful feature. When writing SMPTE, if the Write Switch is pressed in
and held for a prolonged time, the Read/Write Indicator LED will
