Rackmount
Model: PRO-2000RM
Limitimer PRO-2000RM is a speaker timer system for studio installation. Housed in a 1U rackmount
enclosure, it combines the Limitimer controller with an Ethernet port and a serial data port to popular
touch panels and show control systems. It can drive Limitimer signal lights by hardwire, over Bluetooth
wireless, or across local and wide area networks. It can also be controlled by other client-configured
timers in the Limitimer family.
Front DIP switches allow for easy access to set sound cues, volume, counting format, seconds display,
and wireless channels. Through a front panel USB port, a PC can access user guides, set-up examples
and touch panel interface documents, as well as store personal documents or launch an application to
configure network properties (IP address, gateway, mask, port and DHCP).

Timer Operation
Quick Start – Setup
Plug the power supply into the rear panel. Use the DSan Power Supply Model WP (110-220 V AC) which
can provide 12 volts at up to 1 amp — enough to drive the timer and two connected signal lights. (For
additional signal lights, use a larger power supply or a power booster hub. The signal lights may also be
powered locally. See Accessories, Page 8.)
Push the power switch (A) to turn on.
Set Total Time – Use the Up-Down arrow buttons below the Total Time display (B). Each button-press
increments or decrements one minute. To set seconds, press the "Set Seconds" button. The displays
will blink. While blinking, each button-press increments or decrements one second.
Set Sum-up Time – Use the Up-Down arrow buttons
below the Sum-Up display (C). Sum-Up time represents
the amount of time remaining when the yellow phase
light (E) is illuminated. Note: Sum-Up Time cannot be
greater than Total Time.
Press Start (D) – The time displays turn bright red, the phase lights (E) illuminate, and the Time
Remaining display (F) begins counting. Note: Counting is, by default, in the down direction and by
MINUTES:SECONDS. This can be changed to the counting up direction and/or by HOURS:MINUTES using dip
switches. (See Dip Switch Settings page 5.)
Programs
Programs are useful for debates or contests where pre-set timing formats must be selected quickly or
where timekeeping is separate for each speaker.
To pre-set a program, select that program.
Set Total Time, Sum-up Time, Blink, and Beep.
These settings are saved for the selected program.
Programs 1, 2, and 3 cannot run simultaneously with
each other. Toggling between these programs stops the
clock if it is running. Program 4 (Session) can run
simultaneously in background while Program 1, 2 or 3 is running and is selected for display.
A dimly lit Program LED indicates that a program is running in background. A brightly lit LED indicates
that the program is selected for display. A signal light set to display all programs will display the
program that is selected on the timer. Signal lights can be set to display any or all programs using the
signal light dip switches 1-4.
Press Clear to return the settings of a selected program to 0:00. Press Repeat to reset Time Remaining
to Total Time.

Options: Beep – Blink
Note: Beep and blink settings, like time settings, are set for each individual Program.
Blink on: Red light starts to blink after it comes on at Time Remaining = 0:00.
Beep: Audible cue is sounded when Time Remaining is 0:00 and when red phase light is illuminated. It
continues to beep every other second. See DIP Switch Settings to select the type of sound.
Note: Hold Beep button to manually trigger a single beep.
Signal Light Connections
Note: Signal lights may be purchased separately. (See Signal Lights and Accessories Page 10.)
Hardwire Connections
Signal lights connect with Cat-5 cable. (XLR cable can be used with KES-882 cable adapter. See
Accessories.) The cable uses twisted wire pairs to carry 12 volts, differential data, and ground
reference. Do not connect Signal Light jacks to standard network ports. Dual RJ45 jacks are available on
the rear panel (G) and one on the front panel (H) for signal light connections.
Multiple signal lights can be interconnected via daisy chain or through a power booster hub (PSL-PB6 or
PSL-PB18. See Accessories).

Wireless Connections
Limitimer PRO-2000RM has an integrated Class II Bluetooth transceiver. It can send data to Bluetooth-
equipped signal lights or client-configured timers at distances up to 300 feet. Communication can take
place over four channels with up to 6 Bluetooth receivers connected on each channel. Multiple signal
lights can be connected to a single Bluetooth receiver or a signal light with an integrated receiver.
Match receiver and timer Bluetooth channels using DIP switches 11 and 12 (B). Keep the signal light
and the timer < 20-feet apart during the initial setup. Yellow LEDs on the timer (A) and on the receiver
(C) will illuminate during the first minute of setup. When both LEDs turn green, the timer and signal
light are paired, and they may be separated up to 300 feet.

DIP Switch Settings
Timer and signal lights have DIP switches that control behavior particular to each device. The default
settings are all switches in the UP or ON position. Note: Signal lights use a different DIP switch labelling
where one switch position is marked "OPEN". In this context, the open position means "OFF."
Switch 1. Client-Server
When two or more timers are connected to one or more signal lights, set one timer as Server [ON] and
the other(s) as Client [OFF]. When only one timer is used, it must be a Server (default setting – Switch 1
UP). The Client timer acts as a thin client that sends keystroke commands to control the Server and
displays the Time Remaining. All the time processing is done on the Server.
Switch 2. Counting Program 4 (Session)
MINUTES:SECONDS [ON]; HOURS:MINUTES [OFF]
Switch 3. Counting Programs 1, 2, 3
MINUTES:SECONDS [ON]; HOURS:MINUTES [OFF]
Switch 4. Count direction
Count-Down [ON] or Count-Up [OFF].
If Count-Up, Time Remaining display shows elapsed time.
Switch 5. Count Behavior
Continue after zero [ON] else, stop display at zero. Note, in OFF mode, red light stays on until user
presses “stop".
Switch 6. Sound Volume
High [ON] Low [OFF]
Switch 7+8. Sound Selection
7. ON 8. ON None:
7. OFF 8. ON Buzz
7. ON 8. OFF Ring
7. OFF 8. OFF Chime
Switch 9. Time Settings Permission
Allow time changes while clock is running [ON]
Switch 10. Enable Wireless Transceiver
Set to [OFF] when not using Bluetooth communication
An empty sound. "Beep" pressed on timer outputs a cue to activ
ate a
sound at a signal light that is set for an audible sound

Network Settings
When a PC is connected to the front USB port of Limitimer PRO-2000RM, a flash memory drive
"Limitimer" is enumerated and visible on Windows Explorer. Click on the application "Configure-
Networking ". (Windows® only.) A form appears that shows the network properties of the device.
Make sure that Device “Limitimer” is selected
[A]. (This application is used for other DSan
products as well.)
By default, PRO-2000RM is set to be a “server”
[B] and use a dynamically assigned IP address.
DHCP is unchecked [C]. This is so it will not
disable other devices that may be connected to
your network that are assigned the same IP.
However, it is important for the server to have
a known IP address so that clients can be
configured to point to it. You can change to a
fixed IP address if you are running your own
network or if the network administrator
provides an unused IP address [B]. In this
context, Server is the Device IP Address.
If you are trying to establish a connection
outside of the local area network, you will need
to input the Gateway IP address. This is often
the address of the router itself. Quite
frequently, it is the first address in the range of
addresses that the router can assign to
connected devices. Many consumer routers
use 192.168.1.1 thru 192.168.1.255 as the
range of addresses. In this case, the gateway
address may be 192.168.1.1 and the connected
Limitimer Rackmount may be any other unused
addresses in that range.
The Network Mask determines what part of the IP address is the local area network.
This value should be obtained from your network administrator. Most consumer routers allow a
maximum of 255 IP addresses which are completely contained within the final octet of the router
address. Thus, the mask is usually "255.255.255.0."
An unused port number must also be obtained from the network administrator to send outside requests
to the PRO-2000RM to its assigned internal IP address.

Network status LEDs indicate connection to a network (NETWORK); whether a client
Limitimer (HOST) is connected to the PRO-2000RM; if data is flowing (DATA); and, if
the device is configured as a server (SERVER). (If configured as a client, the Server
LED is off.)
If Limitimer Rackmount is configured as a client, make sure that its DIP switch #1 is the OFF position.
This means that it is not generating its own time data. The DATA LED will not blink until it connects to a
remote timer configured as a server.
If Limitimer Rackmount is configured as a server, make sure that DIP switch #1 is in the ON position so
that it generates all the time data.

Serial Communications
Limitimer communicates with signal lights and client timers via high speed serial connection.
Limitimer Rackmount translates the serial data into easy-to-read and easy-to-send plain-text format and
adds information about the phase lights and other status indicators to the message so that touch panel
controller can simulate the Limitimer console. The text format is available on the RS-232 serial port.
RS-232 protocol uses separate wires for transmit and receive. Limitimer uses a half-
duplex RS-485 protocol where transmit and receive happen on the same wire, but at
separate times in the message. An internal RS-232—RS-485 adapter handles the
interface between Limitimer and touch panel controllers. An external adapter (TP-
2000x) is also available as an accessory.
The touch panel controller port should be configured at 9600 baud with 8 data bits, no
parity, and one stop bit.
The message on the RS-232 port incorporates a checksum.
The Touch Panel API is found in a separate document "LimitimerTouchPanel_API.pdf" on the Limitimer
Rackmount flash drive.

Setups
Limitimer timers and signal lights may be configured in numerous ways. The RS-485 wiring allows many
devices to be interconnected and the number is limited only by available power. Power may be
introduced anywhere but is best connected nearest the most remote lights. Wireless and network
connections may be combined with hard-wired connections. Any number of "client"-configured timers
may be connected to provide multi-point control.
These illustrations show a range of setup possibilities.
Multi-point Time Control
Note: Make sure one timer has DIP switch 1 in the UP (ON) position. The other timers should have the
switch in the OFF position.
Multi-point control can be setup over hard-wire, Bluetooth wireless or Ethernet or any combination.
This works with wireless operation as well.
