DATA SHEET / MANUAL
LEVEL
General Description
e Rane SR 1L Smart Digital Remote is a wired remote
control with a 31 position LED indicator and data encoder. e
SR 1L is electrically compatible with standard RS-485 interfaces
(power required).
e SR 1L mounts in a standard U.S. electrical box with a
minimum depth of 2¼ inches, and flush covered with a standard
Decora® plate cover (not included). e SR 1L replaces and is
fully backwards compatible with the SR 1.
To lock out SR 1L level changes (disabling the knob) yet
still display current settings, disable the encoder by connecting
the ENCODER LOCK terminal to the V– terminal. Use a key
switch, relay, or any old thing that passes electrons. is provides
optional limited access to the level control via a key or other
switch.
Use with other Control Systems
e standard electrical interface and simple communication protocol make the SR 1L an ideal addition to many custom
installs where a programmable controller (such as an Panja or
Crestron) is in use.
For detailed information on using a SR 1L with a system
controller refer to the RaneNotes, “Using a Control System with
an SRM 66” and “Using SR 1Ls with other Rane Products” (at
www.rane.com).
SR 1L
SMART DIGITAL REMOTE
Use with an SRM 66
e SRM 66 uses Output Groups to link the attenuation
level and Limiter gain reduction of one or more Outputs. Any
one of the seven possible SR 1L remote controls can then be assigned to control an Output Group Level. e SRM 66 can also
assign any number of the six possible Output Groups to a Master
Group. Any number of the seven possible SR 1L remotes can
then be assigned to control the Master Group Level. Understanding and utilizing the power of Groups is essential to harness
the power and versatility of the SRM 66.
e Rane SR 1L provides remote level control for one Group
of an SRM 66 Output or Master. e SR 1L has 31 LEDs to
indicate the Group’s current attenuation setting of 0 to 29 dB
(in 1 dB steps) or OFF. Note that the Remotes control the level of a
Group, not the level of an Output.
With up to seven SR 1Ls connected to a single SRM 66,
each SR 1L must be set to a unique address (1-7). e SRM 66
can also assign multiple Remotes to control a single Group. If
the Group’s value is altered via the SRM 66’s front panel or any
other SR 1L, every Remote mapped to that Group is updated to
reflect the new setting.
To communicate between the SRM 66 and the SR 1L Remotes,
set the RIP parameter on the Memory page to SR1 (the default).
e mapping of Remotes to Groups is accomplished via the
Remote to Group page shown to the right. ese settings are
stored in each of the SRM 66’s Memories. When a Memory is
recalled with different mappings, every Remote is updated to
reflect the current value of its new Group.
SRM 66 Remote to Group Assign Page
Any of the Remotes may be assigned to any one of the six (6)
possible Output Groups, to the Master Group or set to off. If a
Groups level is altered by the SRM 66s Group Level Page (see
Figure 3 in the SRM 66 Manual), then every Remote assigned to
that Group is updated to reflect the new setting. If a Group Level
is adjusted by a Remote, then the SRM 66’s Group Level Page is
updated to reflect the new setting.
Each of the 24 Memories stored in the SRM 66 may have
unique assignments for Output to Group, Group to Master Remote and Remote to Group parameters. is allows very flexible
room combining applications and system reconfiguration.

SR 1L Wiring
e SR 1L Remote interface is a powered, half duplex,
(RS-485) party line system (BYOB). Five wires are required to
connect an SR 1L into the SRM 66’s RIP (Remote Interface
Port), or other RS-485 device. Except for the optional Encoder
Lock connection, each of these 5 connections must be wired. Up
to seven SR 1Ls can be wired in any combination of series or star
configurations for a total line length of up to 1000 feet (305 meters), [assuming the use of high quality shielded dual twisted pair
cables]. Only the SR 1L farthest away from the SRM 66 should
have its RT (termination) engaged (see diagram). See the SRM 66
Manual for more details on RIP wiring recommendations.
Hook the Shield connection to the cable’s shield for best
emission suppression. e loop at the back of the SR 1L chassis is
provided for a cable tie-wrap.
To lockout the encoder, short the Encoder Lock connection
to the -V connection. e LED display remains functional.
SR 1L Troubleshooting
Double-check all wiring for accuracy before power is
applied via the SRM 66. A single LED on the SR 1L should
light immediately after SRM 66 power is applied. A blinking
LED indicates that it has not yet detected communication on the
Port. is is common until the SRM 66 has fully initialized but
should not happen after that point. If after SRM 66 power up, an
SR 1L LED blinks or does not respond, one of several problems is to
blame. Either the wiring is incorrect, the SR 1L address is invalid
(must be between 1 and 7, each remote different), the SRM 66 is
not in SR1 mode (under the RIP parameter in the Memory Edit
page), or the SR 1L’s ENCODER LOCK terminal is shorted,
thus locking out the encoder. Also, the SRM 66 Remote to Group
assignment may be set to Off, thus disabling the entire SR 1L, not
just the encoder.

Advanced SRM 66 & SR 1L Applications
A single SR 1L can control Output Groups across multiple
SRM 66s. For more information on this Master/Slave functionality, see the RaneNote “Advanced Applications of the Ingenious
SRM 66 and SR 1L.”
For room controller fans out there, two more RaneNotes
of interest are “Using a Control System with an SRM 66” and
“Using SR 1Ls with Other Rane Products.” ese RaneNotes
happen to cover AMX, but the Device Control Language and
complete communications details are covered for easy incorporation into Crestron systems. See the “Advanced Applications”
section below for more functions.
Software is available for download for AMX and Crestron
users at www.rane.com/raneware.html.
