System Diagnostics
Introduction
The WACS-2 System can be removed from the host machine and connected to an IBM-compatible
personal computer (PC) in two different ways for maintenance and diagnostic testing.
Figure 4-1 shows the WACS-2 connected to the PC through its host interface cable. This interface
allows the unit to be operated from a P.C. running a “Host Simulator”. When connected in this
manner, the PC simulates a host machine and allows the user to insert notes and monitor
acceptance.
Equipment and Software Required for ARDAC-2 Host Simulator
To operate the WACS-2 in diagnostic (bench) mode, you will need the following items:
1. IBM-compatible personal computer (PC), 80286, or better, running at 16MHz (minimum).
2. This PC must have one available serial (COM) port capable of running at 19,200 baud.
3. Money Controls ARDAC-2 Host Simulator Software.
4. An extension or adapter cable may be required to connect the 25-pin connector on the chassis to
the PC serial port (9-pin or 25-pin).
