Serial Communications — In order to configure any transceiver, a 9-pin RS-232 cable must be used. This is neces- sary because Pin 4 is used to transmit the configuration data into EEPROM and other pins are used during the configuration process as well (see Table 2). A 9-pin RS-232 cable is included with all stand-alone transceivers.

The 9-wire cable must be used in the following cases:

•when using the Configuration Manager to initialize/ setup a transceiver

•when a Carrier CCN Interface is connected via the RS-232 port

•when field upgrading the transceiver software

Software Installation

The software has the following requirements:

•Windows® 95/98 or above (depending on software used)

•Pentium processor 233 MHz or higher

•1 available RS-232 serial port

•Minimum 32 MB DRAM

•Maximum 20 MB hard disk space for Configuration Manager

CONFIGURATION MANAGER — The Configuration Man- ager program is used to configure all transceivers.

To install the Configuration Manager software, perform the following procedure:

1.Make sure all Windows applications are closed.

2.Insert the Installation CD-ROM into the appropriate drive. Select folder “CONFIG_111300” then select “Disk 1”.

3.Open the contents of the drive using Windows Explorer or My Computer.

NOTE: Take note of all warnings and notes that refer to computer/software requirements when running this program.

4.Double-click on “Setup.exe.”

5.Follow the on-screen instructions.

Antenna Selection and Location — Several factors

effect signal strength:

1.Location

a. Line of sight between antennas is always preferred.

b. Locations directly adjacent to walls or other structures should be avoided for omni-directional antennas.

c.Barriers between antennas should always be con- sidered (see barrier information on page 16 for degree of penetration).

d.Antennas should be moved within the desired space to determine if a better location within the desired area can be found.

2.Polarization

a.Antennas must be oriented in the same plane. For example, omni-directional stick antennas must both be vertical in the same plane in order for reli- able signal reception.

b.Directional antennas must be oriented in the same plane utilizing the vertical pole identification on the antenna.

3.Omni-directional vs. Directional

a.Omni-directional antennas provide essentially equal signal strength around the antenna.

b.Omni-directional antennas can receive a signal coming from virtually any direction in relation to the antenna as long as polarization is not a factor.

c.Directional antennas provide greater signal strength in the direction that the antenna is oriented.

d.Directional antennas are labeled with a vertical pole for proper orientation with both omni- directional and directional antennas.

e.Directional antennas should be pointed in the direction of the receiving antenna.

f.Directional antennas will not receive any signals coming from behind the antenna.

g.Directional antennas should be rotated to deter- mine if bouncing the wireless signal can be utilized in order to achieve wireless communications.

h.For best results it is recommended that a direc- tional antenna be used in conjunction with an omni-directional antenna. With this setup signal strength is improved while antenna lineup is fairly straightforward.
