Controller error responses

When the RAC 104 receives an SIS command and determines that it is valid, it performs the command and sends a response to the host device. If the controller is unable to perform the command because the command is invalid or contains invalid parameters, the contoller returns an error response to the host. The error response codes are:

E01 — Invalid channel number (too large)

E10 — Invalid command

E13 — Invalid value (out of range)

E14 — Invalid setting at this time (i.e., setting outside the upper or lower value limit)

E23 — Firmware update failure

Using the command/response table

The command/response table begins on the next page. Upper and lower case letters can be used interchangeably in the command field except where noted. Symbols are used throughout the table to represent variables in the command/ response fields. An ASCII-to-hexadecimal (HEX) conversion table and symbol definitions are provided below. Command and response examples are shown throughout the table.
