Appendix B: Using Serial IQ Modules
The serial IQ module is a serial-to-VGA converter that allows VT100-capable devices to be viewed
from the AutoView 3050/3100/3200 switch local port or the OBWI. 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 AutoView 3050/3100/3200 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 se
nd and receive serial data.
• Configuration: This mode enables you to specify AutoView 3050/3100/3200 switch
commun
ication 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 Ctrl-F8 will activate the Configuration screen of the IQ module’s Terminal 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 s
erial 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
op
tions 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
op
tions 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).
• AutoView 3050/3100/3200/CD Mode: This option allows you to control how the AutoView
3
050
/3100/3200 switch and CD lines operate. Available options are Always on and Toggle.
When in Toggle mode, AutoView 3050/3100/3200 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.
