Communication and Control, cont’d
Pacing and handshaking are not supported on captive screw connectors.
All of the bidirectional serial ports are completely software configurable. Baud rates can be set up to 115Kbs. Using the Simple Instruction Set (SIS) commands found in the Command/ Response Table for Simple Instruction Set later in this chapter, these ports can be configured to control most serial devices. Once a port is configured and properly cabled to the controlled device, serial commands can be issued to the port from a Web page, Telnet connection, or by using the advanced scripting capability built into the IP Link product family.
Communication with the Interface

The
5.5or higher) can be used, but if using Internet Explorer, you must also have Microsoft Script (version 5.6 or higher).
The PC used to access the Web server must have a connection in common with the IPL T interface. In other words, both the unit and the PC should be connected to your local intranet or the Internet.
If you have established passwords for the interface, you will be shown a Password window when your browser accesses the IPL T unit (but not when you initially access the Web server, since no passwords have been established). Your level of control over the interface will depend on the password you enter in this password screen. If you enter the administrator’s password, you will have control of all matters of configuration. If you enter a user password, you will be restricted to control of A/V devices and viewing status.
