1.0 Overview

Teletronics' advanced WINC 2400C1 modem is a versatile wireless synchronous modem that compatibly
interfaces with a variety of external synchronous data devices, including multiplexers, routers, bridges,
PBXs, frame relays, etc. Acting as “wireless airports”, the WINC 2400C’s transmit and receive data
information for the synchronous data devices located in separated locations without cables and expensive
network operating system. The modem operates at very low power in the FCC designated ISM
(Instrument, Scientific and Medical) frequency band between 2400 and 2483 MHz and user requires no
license to operate. Using state-of-the-art spread spectrum technology, the WINC 2400C offers point-to­point linkage and point-to-multipoint broadcasting data communications function. Typical applications
include multichannels of voice, facsimile, and data up to 128 Kbps.

2.0 Technical Information

The WINC 2400C transfers data between synchronous devices at selectable data rate, from 1.2, 2.4, 4.8,

9.6, 56.0, 64.0, to 128.0 Kbps.

WINC 2400C provides all comparable features as WINC 900C, the existing 900 MHz version, operating
within the 2404 - 2483 MHz frequency band. The channel bandwidth of transmission is 4 Mhz and there
are twenty (20) independent 4 MHz channels available for choice when operation. Due to different
environmental application requirement, at least 3 different radiation power levels are offered, either
50mW, 100mW, or 500mW. Please check the product sheet that comes with the WINC 2400C you
purchased. Depending on the material of walls and ceilings, indoor operation as much as 30 to 50
meters. For outdoor unobstructed environment, the operating range of the modem is approximately 1
kilometer using the standard rubber omni-directional antenna. Using a high-gain Yagi antenna,
operating ranges can increase to up to 30 km.

The WINC 2400C uses direct-sequence spread spectrum technology with a fixed PN spreading code for
access. Differentially QPSK modulation is employed. The air-link operates in a Time Division Duplex
(TDD) mode which performs the full-duplex function to the user. Sensitivity is better than -85 dBm (not
including spreading gain). See Appendix C for a detailed technical specification of the modem.

In general, the WINC 2400C operates automatically with little need for user intervention. Both channel
selection and power control are automatic and transparent to the user guarantying that communications
occur at the lowest power sufficient to maintain the link on a channel that is least noisy.

3.0 Equipment Check List

Each WINC 2400C is uniquely identified by a digital address code. The address enables two intended
modem units to establish a communications link. The seven (7) digit address can be found on the label
affixed to the left side of the unit and is defined by the right-most seven (7) digits of the serial number.
The device address can also be found by using the ATI0 command to be further discussed in Appendix A.
A DB-25 female connector is used for synchronous operation. (There is also a port, the DB-9 male
connector. It is used for configuring the unit prier to first operation by a PC notebook. Once it is
configured, the port is no longer needed for operation).

If anything is missing or damaged, please contact your supplier immediately.

4.0 Hardware Installation (Cabling)

Installing a WINC 2400C involves a simple cable connection between it and a synchronous data device.
However, beffore you can make it operational for wireless data transmission among various units of
WINC 2400Cs, each unit has to be properly configurated. The configuratiion of each unit requires the
connection with a PC or a termainal. (After the configuration task is completed, the PC or terminal can
either stay connected for monitoring purpose or be disconnected). The following instructions are provided
to assist you in wiring peier to the configuration.

1. Turn your computer off before starting.

2. Connect the asynchronous configuration port of the WINC 2400C to your computer's
serial port using an RS-232, DB-9 connector and associated cable.

3. The DB-25 connector of WINC 2400C is used to connect to a synchronous device like a digital
multiplexer or LAN bridge. This DB-25 port can be configured as RS-23, V.35, or RS-422 by
configuration software. Please refer to Appendix C for detailed pin definition for different interfaces.

4. Attach the rubber omni antenna to the matching connector on the rear of the WINC 2400C.

5. With the WINC 2400C power switch in the off position, connect the power cord to the rear of the unit
and plug it into the electrical jack nearest your equipment. The WINC 2400C is equipped with a
universal power supply for 110-220 volts and will internally adjust itself for either voltage.

6. Turn on the computer and the synchronous device, if applicable.

7. Turn on the WINC 2400C modem. The WINC 2400C performs a brief self-test. LED indicator
lights will be displayed on the front panel. Each LED displays single or dual colors. Green indicates
an active state or signal presence, whereas red indicates otherwise. See Appendix C, WINC 2400C
Synchronous Interface Status, for LED indicator definitions.

After the self-test, you are now ready to do the configuration. This will be presented in the next section..
