Processor Error Responses

When the USP 507 receives an SIS command and determines that it is valid, it performs the command and sends a response to the host device. If the processor is unable to perform the command because the command is invalid or contains invalid parameters, the processor returns an error response to the host. The error response codes are:

E01 — Invalid input channel number (out of range)

E10 — Invalid command

E11 — Invalid preset number

E12 — Invalid output number/port number

E13 — Invalid parameter (out of range)

E14 — Command not available for this configuration

E17 — Invalid command for this signal type

E22 — Busy

E24 — Privilege violation

E25 — Device not present

E26 — Maximum number of connections exceeded

E27 — Invalid event number

E28 — Bad filename/file not found

Using the Command/Response Table for SIS Commands

The command/response table begins on page 4-7. Lowercase letters are acceptable in the command field except where indicated. The table below shows the hexadecimal equivalent of ASCII characters used in the command/response tables.
