Galil Motion Control DMC-18 2 Series User Manual page 53

The Galil SmartTERM application installation (as well as WSDK, ActiveX, and DMCWIN32
installations) includes the necessary drivers and .DLL files required to communicate with the Galil
controller. The drivers are automatically installed and default communications settings are applied to
the device by the driver when a card is installed as per the installation procedure outlined in Ch.2.
However, some advanced settings are available to modify the communications methods and data
record access. These settings are accessed through the Galil Registry Editor after the card is properly
installed.
Galil Registry Editor
The "Edit Registry" dialog box (shown in Fig 4.4) can be accessed by selecting Controller
Registration... under the Tools menu (or by selecting the toolbar icon with the magnifying glass)
within DMC SmartTERM. The Edit Registry dialog shows the current controller models installed to
the PC along with their associated I/O addresses, interrupt lines, and controller serial numbers. The
Galil Registry is part of the DMCReg.ocx ActiveX object (refer to Fig 4.1). This ActiveX control is
used to create, maintain, and modify the critical communication parameters, which are discussed next.
Setting Communications Parameters and Methods
To access the Controller Communication Parameters dialog, highlight the desired controller in the
Galil Registry Editor accessed through SmartTERM and select the Properties command button.
The timeout property under the General Parameters tab (shown in Fig 4.5) allows the user to select
the timeout period that the Galil software waits for a response from the controller before generating an
error. If the controller does not reply with the data response and a colon (or just a colon for commands
that do not invoke responses), then the Galil software API will generate the timeout error code -1 (A
