Connections to timer

Wired

Connect to a Limitimer PRO-2000 timer console
with ordinary Cat-5 cable to the RJ45 input jack.
12V power flows through the cable so that only
the timer or the signal light need be externally
powered.

XLR cable may also be used but both timer and
signal light should be powered.

For cable runs greater than 1000-feet, always provide local power to the signal light using the included 1­Amp power supply (center pin +).

Wireless

Model ASL4-ND3BT has an integrated Bluetooth receiver module that is enabled when DIP switch #10
(See below) is in the ON position. For wireless operation, use the included external power supply.

Pair with a Bluetooth enabled Limitimer that is configured with the same RF channel (DIP switches 11
and 12). Up to 7 signal lights can be paired to one timer. Up to 4 signal light―mer networks can
operate in proximity on unique RF channels.

Wireless range is about 250-feet.

Note:

When pairing, the signal light should be kept within 25-feet of the timer. Once the signal light
displays the timer settings, pairing is achieved. Now, the signal light can receive timer data from the full
distance range.

Alternate Wireless Connection

Model ASL4-ND3 does not have an integrated
Bluetooth receiver. A standalone Bluetooth receiver
(DSan model TR-2000BT) may be used to wirelessly
capture Limitimer timer data over the same distance,
and then connect to one or more signal lights.

Connections to other signal lights

Connect any Limitimer signal light to the output port of
the ASL4-ND3. Data and power from a Limitimer
connected to the input port will flow to the connected signal light along with power.

Switch Settings

Located on the front lower right

1-4 Display Programs

Limitimer PRO-2000 timer provides four individual timing
programs. Use switches 1 to 4 to configure the signal light to
display any of these programs. If it is configured to display all
the programs, it will show the program that is active on the
timer.

Program 4 can run in background. It may be used to time an
entire session while Programs 1, 2 or 3 may be used for
individual presentations. Only one of these programs may be
running at one time.

5 Counting

When set to ON, the display will stop at
overtime. Set to OFF to display overtime.

0:00

even though the timer may continue counting

6 Clock Display Configuration

When a connected Limiitimer timer is turned off, or no timer is connected, ASL4-ND3 can display time­of-day, if enabled. See switch # 9.

Set to ON for 12-hour clock; OFF for 24-hour clock display.

7 -8 Not used

9 Time-of-day Clock

Signal Light must be locally powered. It will display the
time of day when a connected timer is switched off. If
switch 9 is set to OFF (Up), digits will be blank when
timer is turned off.

Set time-of day using the wo push-button switches on
the front lower left. corner

10 Enable Bluetooth Receiver (Model ASL4-ND3BT)

Set to ON (Down) to receive time data wirelessly from a Bluetooth-enabled timer.

11-12 RF Channel

Match with switches 11 and 12 on a timer. Up
to 7 signal lights can be wirelessly connected to a
wireless Limitimer. Up to 4 timer-signal light

Power Requirements

ASL4-ND3 is supplied with a 12V 1Amp external power transformer that accepts 110-240 V mains fitted with
the appropriate plug for your country. The signal light draws approximately 500 mAmp. The timer itself
draws about 300 mAmp. Therefore, it is possible to operate both the timer and the audience signal light
with one power supply – connected to either the timer or the signal light. When the cable connecting the

signal light to the timer is greater than 100-feet, both the signal light and the timer should be locally
powered.

Note: Timer-signal light connections can be made with XLR cable. Because this is three-wire cable whereas
the Cat-5 cable has four twisted pairs, the effective connection distance is about half. However, as long as
both the signal light and timer are locally powered, XLR cable can be used for long runs.

Installations

ASL4-ND3 and ASL4-ND3BT have a stainless-steel bracket that
flips open to allow the signal light to stand at 45o on a stage
floor.

ASL4-ND3 and ASL4-ND3BT have 4 M7-.07
threaded bushings spaced to accept standard
100MM VESA hardware.
