PRELIMINARY SIS Programming and Control 5-2 The IPL T PC1 can be remotely set up and controlled via a host computer or other device (such as a switch, hub, or router) attached to the rear panel LAN port. The PC1 must be configured before use. As shipped, the PC1 works as a standalone interface, but cannot control any other devices until it is configured. You can set up the PC1 using Global Configurator, the Web pages (see chapter 4), or Extron’s Simple Instruction Set (SIS ) commands (discussed in this chapter). The Web pages, Global Configurator, and SIS methods can be accessed via an Ethernet LAN connection. LAN port defaults: IP address: 192.168.254.254 Gateway IP address: 0.0.0.0 Subnet mask: 255.255.0.0 DHCP: Off Host-to-interface Communications SIS commands consist of one or more characters per field. No special characters are required to begin or end a command sequence. When the PC1 determines that a command is valid, it executes the command and sends a response to the host device. All responses from the interface to the host end with a carriage return and a line feed (CR/LF = ), which signals the end of the response character string. (A string is one or more characters.) Messages initiated by the IPL T PC1 When a local event such as a front panel selection takes place, the PC1 responds by sending a message to the host (visible only when the PC1 is in verbose mode). No response is required from the host. The following PC1-initiated messages are sent (underlined): (c) Copyright 2007, Extron Electronics, IPL T PC1, Vx.xx, 60-544-xx Www, DD Mmm 2007 hh:mm:ss The PC1 sends the boot and copyright messages when it first powers on and is connected via Telnet or TCP/IP. Vx.xx is the firmware version number. The current date and time are displayed. If you are using a Telnet connection, the copyright message, day (Www) date, and time are followed by a password prompt. Password information The “ Password:” prompt is displayed only if there is a password defined in the unit. It requires a password (administrator level or user level) followed by a carriage return. The prompt is repeated if the correct password is not entered. If the correct password is entered, the unit responds with “ Login Administrator ” or “ Login User ,” depending on the password entered. If the passwords are the same for both administrator and user, the unit defaults to administrator privileges. Error responses When the PC1 receives a valid SIS command, it executes the command and sends a response to the host device. If the PC1 is unable to execute the command because the command is invalid or it contains invalid parameters, it returns an error response to the host. IPL T PC1 SIS Programming and Control
The error response codes and their descriptions are as follows: E12 – Invalid port number E13 – Invalid value (the number is out of range/too large) E14 – Not valid for this configuration E17 – System has timed out. E22 – Busy E24 – Privilege violation E25 – Device is not present. E26 – Maximum number of connections has been exceeded. E27 – Invalid event number E28 – Bad filename or file not found E30 – Hardware failure (followed by a colon [:] and a descriptor number) E31 – Attempt to break port pass-through when it was not set Error response references The following superscripted numbers are used within the command descriptions on the following pages to identify commands that may respond as shown: 14 = commands that give an E14 (invalid command for this configuration) response if sent to an IPL product whose current configuration does not support the command. 24 = commands that give an E24 (privilege violation) response if you are not logged in at the administrator level. 27 = commands that may yield an E27 (invalid event number) response. 28 = commands that may give an E28 (file not found) response. Using the Command/Response Table The PC1 can be controlled via either a Telnet (port 23) connection or a Web browser (port 80) connection. The ASCII and URL commands listed in the tables starting on page 5-8 perform the same functions, but they are encoded differently to accommodate the requirements of each port (Telnet or Web). The ASCII to hexadecimal (HEX) conversion table below is for use with the command/response tables. ASCII to HEX Conversion Table • The command/response tables list valid ASCII (for Telnet) command codes, the corresponding URL (universal resource locator) encoded (for Web browsers) command codes, the interface’s responses to the host, and a description of the command’s function or the results of executing the command. Upper- and lowercase characters may be used interchangeably in the command fields unless otherwise specified. Commands may be sent back-to-back without spaces (for example, 2!65V1Z).
