Appendix C: Using Serial IQ Modules

The serial IQ module is a serial-to-VGA converter that allows VT100-capable devices to be
viewed from the DSR switch local port, the on-board web interface, or by using the DSView 3
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 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 on a VT100 terminal.
Serial IQ module modes
The following modes can be accessed from the serial IQ module:
• On-Line: This mode enables you to send and receive serial data.
• Configuration: This mode enables you to specify DSR switch communication parameters,
the appearance of the Terminal Applications menu and key combinations for specific
actions and macros.
• History: This mode enables you to review serial data.
Configuring the serial IQ module
NOTE: The serial IQ module is a DCE device and only supports VT100 terminal emulation.
Pressing

Applications menu, which enables you to configure your serial IQ 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).
