CHAPTER 4: Digital Operation with Pilot Module
Your Smart-Trak 2 instrument may be operated in three different ways:
THREE CONTROL OPTIONS
A.
Analog Input/Output Operation (Chapter 3):
Using analog
input/output signals at the HD DB-15 connector.
B.
Digital Operation with Pilot Module (This Chapter):
Using the
optional Pilot Module.
C.
Digital Operation with RS-232 and Smart-Trak 2 Software
(Chapter 5):
Using the RS-232 Smart-Trak 2 Software package and a
computer running the Windows operating system.
This chapter will discuss the second of these—Digital Operation with the optional
Pilot Module. Please see alternate chapters for other options.
Although you have chosen to use the optional Pilot Module, please note that all the
Analog control functions are still available on your instrument. Consult Chapter 3
for details on Analog operation. Also, computer control using the RS-232
communication is available. See Chapter 5 for details on operation with a computer.
CAUTION
—If RS-232 digital communication is to be used in conjunction with the
Pilot Module, the HD DB15 connector must be properly wired with a three wire
serial DB9 cable to your computer. Often, this is done with the same HD DB15 that
supplies power to your instrument. You can run both RS-232 communication and
Pilot Module communications in parallel, but the unit will only respond to one set of
commands at a time. DO NOT attempt to control the unit simultaneously with both
the Pilot Module and the computer, this can lock up the unit.
Introduction to Pilot Module Features and Capabilities
The optional Pilot Module functions as both display and a control unit for your
Smart-Trak 2 instrument. The standard Pilot Module is available mounted directly
on the face of your instrument or as a handheld / remote mountable control interface
attached to the Smart-Trak 2 via a detachable cable.
