Using Serial IQ Modules

Both DSRIQ-SRL and MPUIQ-SRLserial modules are supported and described in the following sections.

Using DSRIQ-SRL Modules

The DSRIQ-SRL module is a serial-to-VGA converter that allows VT100-capable devices to be viewed from the

MergePoint Unity switch local port, the OBWI, 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 MergePoint Unity 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.

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 MergePoint Unity 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 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-SRL 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 MergePoint Unity 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.

• Enter Sends: This option enables you to specify the keys that are transmitted when Enter is pressed.

Available options are <CR> (Enter), which moves the cursor to the left side of the screen, or <CR><LF>

(Enter-Linefeed), which moves the cursor to the left side of the screen and down one line.
