User manual RANE SR 2

[. . . ] OPERATORS MANUAL SR 2 SMART REMOTE Quick Start Who would guess that a little box with one knob could have such a large manual?At least read this section for the basics. Since Decora plates come in different colors, each SR 2 is shipped with 4 different color inserts for installation behind the lens (we ship them without an insert installed). Colors included are white (w/ black logo), white (w/ almond logo), almond (w/ black logo) and black ( w/ white logo) which accommodate most applications. [. . . ] ($5 + $80) The SR 2 always returns its address switch setting plus $80. ($addr + $80) The address switch must be set in the range [0, 7]. <msgtype> The msgtype is a one byte set of flags indicating options, bit 7=MSB: bit 0) set = checksum is valid bit 1) set = there has been an error (response only) bit 2-5) reserved, cleared to 0 bit 6) always 1 bit 7) always 0 If the controller wants the SR 2 to verify the checksum, it would send a value of $41, or an ASCII `A'. If the controller wants the SR 2 to ignore the checksum, it would send a value of $40, or an ASCII `@'. The SR 2 echoes back the <msgtype> it was sent. In the case of an error, the SR 2 sets bit 1. <devtype> The SR 2 device type value is $32, or an ASCII `2'. The SR 2 also accepts a value of $30, or an ASCII `0', the universal device type used for polling. The SR 2 always returns its device type of $32. <checksum> The checksum is defined as the sum of the ASCII encoded values of the <command/data> section. The sum is then masked with $007F to produce one byte with the MSB set to zero. The controller would send a valid checksum as defined above if it sent a value of $41 for the <msgtype>. The SR 2 then verifies the sent checksum by calculating the checksum from the data it received in the <command/data> section of the sent message. On the other hand, if the controller sent a value of $40 for the <msgtype> the SR 2 ignores the sent checksum. The controller must always send a checksum less than or equal to $7F, even if it intends for the SR 2 to ignore it. The SR 2 <checksum> response is based on the <msgtype> it was sent. If the SR 2 received a <msgtype> of $41, it returns a valid checksum (as defined) calculated from it's response data. If the SR 2 received a <msgtype> of $40, it returns zero. Manual-9 <command/data> The general format is <cmd1, arg1, arg2, . . . , cmd2, arg1, . . . >. The commas are part of the <command/data> structure and act as delimiters between the ASCII encoded commands and data. Concatenation of commands is limited to four commands. Text string arguments are delimited with quotes ("String"). If the string argument contains quotes, an accent character (`) placed in the string argument will be interpreted by the SR 2 as a double quote character ("). [. . . ] Response: "OK" Manual-13 Stored Parameter List (SPL) Below is a table of stored parameters followed by descriptions of each parameter. Index 1 2 3 4 5 Description Auto Level Auto Second Level Auto Lock Baud Rate RW 485 Transmit Delay (ms) Values 0-1 0-1 0-1 0-4 2 - 200 Setting Meaning 1 1 1 2 10 disabled - enabled disabled - enabled disabled - enabled 0 = 9600, 1 = 19200, 2 = 38400, 3 = 57600, 4 = 115200 2 - 200 ms Parameter Descriptions 1. Auto Level configuration affects the result of turning the encoder. Turning the encoder without pushing it in updates the command state to an Encoder Left for a counter clockwise turn or an Encoder Right for a clockwise turn unless the device is locked. [. . . ]
