As soon as mains power is applied, the
Model 58’s power present LED will light.
The Model 59 will go through its power-up
sequence lighting each LED in a rapid
sequence.
Note that any time a Model 58 configura-
tion DIP switch is changed, mains power
on all Model 58 units must be discon-
nected and reconnected. This ensures
that the logic circuitry is fully reset to the
new operating parameters. (This is not a
bug in software—we designed it this way
to ensure that the performance would be
correct!) Refer to the Configuration section
of this guide for details on setting the DIP
switches.
Configuration
After the physical installation has been
completed, several configuration issues
must be addressed. On the Model 58
Central Controllers, the unit ID and operat-
ing mode must be set. In addition, the
input and output signal levels must be
calibrated using the trim potentiometers.
As a final step, the operating parameters
of the system will be set using the Model
59 Control Console’s configuration mode.
Note that any time a Model 58 DIP switch
is changed, the data LED (located to the
right of the switches) will flash. This is
normal, being provided for factory confir-
mation of switch operation.
Model 58 Unit Identification
Numbers
A unique unit identification (ID) number
must be assigned to each Model 58.
This allows commands from the Model 59
Control Console can be correctly inter-
preted. A simple binary method sets the
unit ID, using positions one through four of
an 8-position DIP switch, which is located
on the front panel. The DIP switch posi-
tions are labeled 1-8, with position 1 on
the left side. A switch in the off (down)
position is considered to be in the 0 state.
A switch in the on (up) position is consid-
ered to be in the 1 state.
Setting the unit ID is very simple: A Model
58 set for unit ID 1 supports output chan-
nels 1 and 2 on the Model 59, a Model 58
set for unit ID 2 supports output channels
3 and 4, etc. A system using three Model
58 Central Controllers to create a 6-chan-
nel monitor system would have unit ID
numbers 1, 2, and 3 assigned. Refer
to Figure 11 for the exact DIP switch
settings.
You curious types might wonder why four
bits were reserved for unit IDs, rather than
just two or three. In most cases, only the
first four unit ID numbers will be used,
