Appendix C: Using DSRIQ-SRL Modules
The DSRIQ-SRL module is a serial-to-VGA converter which permits VT100-capable devices to be
viewed from the DSR2035/8035 switch 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 DSR2035/8035 switch as
though it came from a VGA target. 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.
• Configuration: This mode enables you to specify DSR2035/8035 switch communication
parameters, the appearance of the Terminal Applications menu and key combinations for spe-
cific actions and macros.
• History: This mode enables you to review serial data.
Configuring the DSRIQ-SRL module
NOTE: The DSRIQ-SRL module is a DCE device and only supports VT100 terminal emulation.
Pressing Ctrl-F8 will activate the Configuration screen of the DSRIQ module’s Terminal
Applications menu, which enables you to configure your DSRIQ-SRL module.
NOTE: When any Terminal Applications menu is active, pressing Enter saves changes and returns you to the
previous screen. Pressing Escape returns you to the previous screen without saving changes.
Within the Terminal Applications menu’s Configuration screen, you can modify the
following options:
• Baud Rate: This option allows you to specify the serial port communications speed. Available
options are 300, 1200, 2400, 9600, 19,200, 34,800, 57,600 or 115,200 bps. The default value
is 9600.
• Parity: This option allows you to specify the serial port’s 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 flow control. Available
options are NONE, XOn/XOff (software) and RTS/CTS (hardware). The default value
is NONE. If you select a bps rate of 115,200, the only available flow control is
RTS/CTS (hardware).
• DSR/CD Mode: This option allows you to control how the DSR2035/8035 switch and CD
lines operate. Available options are Always on and Toggle. When in Toggle mode, DSR and
CD lines are turned off for one-half second and then turned on each time a module is selected
or deselected. The default value is Always on.
