Additional Slink commands for Slink Tuners/Amps

Hello,

I have a Slinke hooked up to my Sony STRDE805G, I was exploring the Slink commands I can send my Sony AMP over the last weekend and I figured out some additional commands not in the current tunersls.cde (and matching tunerslr.cde) file.

These new commands relate to the AM/FM tuning and could probably be added into the tunersls.cde file for the next release. [if these have already been noted elsewhere I aplogise for this but could the tunersls.cde be updated accordingly. As my AMP is about 3 years old now its possible that the newer models (8x5 and 9x5 and 10xx models) have additional commands for the tuner that differ from these, and/or have more preset groups - mine has 3 preset groups of 9 stations each (group A,B,C).

The comands I uncovered are as follows [in a .cde file compatible format]:

00000100:tune_up # Tune the tuner up by .05Mhz [FM band] or 9/10khz [AM]

00000101:tune_down # tune the tuner down by .05Mhz [FM] or 9/10 Khz [AM]

00000110:scan_up # Scan up the dial and stop at next station tuned in

# [Don't know if scan_up/down wrap around]

00000111:scan_down # scan down the dial and stop at next station tuned in

# hex 08 and 09 we know about - thats preset+ and preset-

01010000ssssssssffffffffFFFFFFFF:tune_byfreq

# Direct Tunes to a particular AM/FM frequency

# ssssssss = hex 00 for FM, hex 01 for AM band

# ffffffffFFFFFFFF is a 2 byte binary value which is the

# desired frequency encoded as a 2 byte unsigned integer

# in the integer range of 531 to 1710 for AM and

# 8750 to 10850 for FM [note you multiply the FM frequency

# in Mhz by 100 and then convert this integer to binary.

# e.g for AM frequency of 756 send cmd hex 50 01 02 F4

# for FM frequency 92.80 send cmd hex 50 00 24 40

# if you leave ffffffffFFFFFFFF off and only send

# ssssssss then you can switch Tuner bands this way.

# except tuning starts at the bottom end of

# the Am/FM band so you have to scan/tune up

#

# if you sent ffffffffFFFFFFFF as hex FFFF then you start

# at the top of the band [and can then tune backwards].

01010001ggggggggssssssss:tune_bypreset

# Tune by preset [Access any Preset station directly]

# gggggggg is the 'Station Group' [A,B or C etc]

# A = (hex) 01, B = 02, C = 03

# ssssssss is the preset number within the group e.g.

# (hex) 01 = preset#1 in the group, 09 = preset#9

# end of CDE file changes.

I have also found an additional command the hex 48 command [which is supported by the amp section also for querying source labels etc].

The tuners version of the 48 command appears to allow you to query/retrieve the information associated with each preset station, the command format [hex] is 48 xx yy, where 48 means, show me the station preset info, xx is the preset Group# [e.g. 01 for Group A, 02 for Group B etc, and yy is the preset# within the group, e.g. preset A9 is 01 09, preset C4 is 03 04.

I don't know what the resultant 'reply text' sent back from the tuner is, I know its long-ish as the slink-e led flashes for some time after the command is sent [and the led flashing length corresponded to long or short preset station information, indicating a reply from the tuner that sort of follows the information being asked for.

I expect the reply from the tuner would indicate the 8 byte station description entered by the user, and also a AM/FM 'band' indicator and possibly a 2 byte field of the frequency of the station in the same format as per the 50 command.

But I have not been able to verify this [someone else may be able to do so and report back].

Any questions or feedback welcomed.
