Appendix B: Using DSRIQ-SRL Modules
The DSRIQ-SRL module is a serial-to-VGA converter which permits VT100-
capable devices to be viewed from the DSR local port or by using the DSView
software. The actual serial data is not accessed, but is merely displayed. All
serial data coming from the target device is displayed in a VT100 window,
placed into a video buffer and sent to the DSR appliance as though it came
from a VGA server. Likewise, keystrokes entered on a keyboard are sent to the
attached device as though they were typed upon a VT100 terminal.
DSRIQ-SRL Module modes
The following modes can be accessed from the DSRIQ-SRL module:
•
On-Line - This mode enables you to send and receive serial data.
•
History - This mode enables you to review serial data.
•
Confi guration - This mode enables you to specify DSR communication
parameters, the appearance of the Terminal Applications menu, key com-
binations for specifi c actions and macros.
Configuring the DSRIQ-SRL
NOTE: The DSRIQ-SRL module is a DCE device and only supports VT100 terminal emulation.
Pressing CTRL-F8 will activate the Configuration Screen, which contains menu
items that allow you to configure your DSRIQ-SRL module.
NOTE: When the Confi guration Screen is active, pressing Enter saves changes and returns you
to the previous screen. Pressing Esc returns you to the previous screen without saving changes.
Within the Configuration Screen, you can modify the following options:
•
Baud Rate - This option allows you to specify the serial port communica-
tions speed in bauds per second (BPS). Available options are 300, 1200,
2400, 9600, 19200, 34800, 57600 or 115200. The default value is 9600.
•
Parity - This option allows you to specify the serial port communications
parity. Available options are EVEN, ODD or NONE. The default value
is NONE.
•
Flow Control - This option allows you to specify the type of serial fl ow
control. Available options are NONE, XOn/XOff (software) and RTS/CTS
(hardware). The default value is NONE. If you select a baud rate of 115200,
the only available fl ow control is RTS/CTS (hardware).
