The standard Reply audience response systems consists of the following items:
Wireless Keypads: Model CRS1200 is a calculator-style radio frequency device with a numeric button panel on the top surface. Keypads are given to each participant in the group. They are used to respond to questions presented during the meeting. Each Audience Response Keypad is powered by an internal 9-volt battery and has no external wires or electrical connections.
Base Station: Model CRS930 processes responses of up to 250 keypads on a single radio channel. There are 8 radio channels available to support a maximum of 2,000 keypads per room.
Base Station Carrycase, Model
CRS899B-32 - High impact ABS shell, die cut foam insert, and locking
clasps. Holds Base Station, 32 keypads, antennas, serial cable, and
power supply.
Lockable Keypad Carrycase, Model CRS899K -

50 keypads for security and shipping protection.
Auditorium/Hall Antenna Kit, Model CRSXANT20
- Consists of a pair of special dipole antennas with mounting slots.
Replaces standard whip antennas to increase Base Station reception.
Includes coaxial cable and connectors to attach antennas to the Base
Station. This type of antenna system is recommended for large audiences
in large areas.
The user of the system provides a personal computer
or notebook and any desired projection device. Any personal computer
with an available serial connection can potentially be used with the
Reply System.
The Standard Reply uses the latest in
wireless technology to turn any meeting into a dynamic interactive experience
for each participant without having to deal with a nightmare of cables
and connectors.
Fleetwood is unique in the marketplace with its patented
system utilizing two separate radio frequencies to provide a two-way
link with the keypads. This design ensures that no responses are missed
by requiring a keypad to retransmit the user's response until it is
properly received by the Base Station. The design also allows the system
to refuse to acknowledge any invalid entries. This is clearly superior
to other technologies using one-way radio or infrared, which do not
provide acknowledgment to the keypad when its entry is received and
do not have any way of rejecting invalid entries.
The Base Station is the control center for the system
and operates according to commands issued by the application software.
Each Base Station can process responses from up to 250 Fleetwood Reply
wireless keypads.
A radio frequency with an assigned channel number is used
by the Base Station to address each individual keypad. This frequency
is modulated by the Base Station microprocessor with a serial digital
address signal that transmits continuously whenever the Base Station
is turned on.
A different radio frequency, but with the same channel
number, is used by the keypad to send response information to the Base
Station. When a key is pressed on the keypad, this transmitter is automatically
activated when addressed by the base transmitter.
Channel numbers are used only to denote the pair of operational
frequencies as used by the Base Station and keypad unit.
How it works
The keypads are rapidly and continually interrogated by the Base Station
'in sequence' to securely process responses. System timing -- the interrogation
cycle -- is adjustable from 0.5-2.5 seconds depending on group size.
Keypads transmit their response information for a duration of 10 milliseconds
(1/100th ofa second) after receiving their address. Once the Base Station
acknowledges a keypad's response information, the keypad turns off to
conserve battery life.
Change/Check Keypad Channel Number
To change the Channel Number, simultaneously hold the "Clear"
key and press key's "9" "7" "3". Then
release the "Clear" key. The current Channel Number will flash
on the LED. The user can now enter any valid 3 digit Channel Number
(002, 003, 004, 006, 007, 008) or press the "Clear" key to
exit the Channel Change Mode. While in the Channel Change Mode, use
the "0/10" key when you want to enter a "0". Up
to four seconds is allowed to enter each digit. After this interval,
the keypad will also shut down. The keypad will shut down after the
third digit is entered.
To check Channel Number follow same procedure as to change
Channel Number, then press "Clear" key when complete.
Keypad Option Commands
Entering option commands is identical to entering a new
Channel Number. All option commands start with the digit "9".
