GINA MODEL 2000-64K

Overview

GINAModel2000-64Kisastand-alone,highfrequency data transceiver using

spreadspectrumtechnology. GINA2000-64Kcapabilitiesinclude

synchronousdata transmission atspeeds to 64Kbps at thedata port withEIA 562/

RS-232,EIA530/RS-530, andV.11(V.35) interfaces. GINA 2000-64K receives

andtransmits data inthe frequency rangeof 2.404 -2.478 Ghz atair speeds of

upto 186Kbps. Communicating atthis speedallows GINA2000-64K tobe a

full(TDD)duplexlink. GINA can beconfiguredto be usedasapoint-to-

Controls and Indicators

Front Panel As shown in Figure 6-2, operating indicators, a voice handset jack, and

the command data port are located on the front panel and consists of:

1. PWR LED (Light Emitting Diode). This LED is lit when

power is applied to the transceiver.

2. TX LED. Indicates that a signal is being transmitted by GINA.

3. RX LED. Indicates a receiving condition on GINA.

4. ST LED. When green, GINA is receiving good data. When

red, data has errors, GINA is receiving bad data, or the GINA

units are not synchronizing.

5. Voice Handset Jack. Standard RJ22 telephone jack for the

GINA handset.

6. RS-232Command Control DataPort. Usedfor programming

during GINA setup. This port communicates at 9600 kbps

asynchronousonly.

NOTE: GINAonlyoperateswith the handsetsuppliedwith the unit.

Data Filter Selection

FL=01 FL=02 FL=03 FL=04

Factory Set to FL=02

RF Channel Selection

Channel selection should be the same on both slave and master.

CH=01~12

Transmit Key ON

TX=00 This setting is for normal operation.

TX=01 10 sec transmit - test purposes only

Transmit Clock Selection

CS=00 Internal transmit clock

CS=01 External transmit clock

CS=02 Loop back command (slave only). This means clock

and data lines are looped back. txd=rxd, ctxc=rxc

Data Speed Selection

DR=01 9.6 Kbps Synchronous

DR=02 19.2 Kbps Synchronous

DR=03 38.4 Kbps Synchronous

DR=04 56 Kbps Synchronous

DR=05 64 Kbps Synchronous. This setting is also used to

allow asynchronous data communication

automatically at speeds of 1.2 to 19.2 Kbps.

Revision of Software

This is factory set but may be determined by checking the Display Status.

The correct settings must be used.

Carrier Detect

CD=00 Carrier detector activates immediately every error

occurrence. This setting causes the CD line to drop

immediately if there is a dropout in the GINA to GINA

link up.

CD=01 Carrier detector holds 2 seconds every error occurrence.

This allows the CD link not to drop unless the GINA

link fade persists longer than 2 seconds.

REResetCommand

RE=01 Resets unit to factory default settings.

TWICE This command must be entered twice. The re-set must

TYPE then be followed by configuring the channel using the

CH command.

After reset:

RC=03 For 2.4 Ghz GINA

Transmitter Power Code

The Transmitter Power Code command is operational and is slated for future

product development. It should be se to 01.

01 = Full Power 03 = 6db down

02 = 3db down 04 = 20db down

RemoteStatus

Allows over the air configuration of the remote’s status. Type the command to

change and use a colon (:) instead of an equal sign (=). For example: To

change the Carrier Detect Code, type: CD:01

IdentificationCode

The ID command is non-operational and is slated for future product

development. It should be set to 01.

Frame Errors Per Second Counter

Indicates path and data integrity of the link.

ZC=00 To hide

ZC=01 To display

ZC=02 To clear and reset

Operations

1. User must confirm all commands as shown above by using a

computer connected to the command control data port at 9600

Kbps with a terminal emulation program.

2. To change a parameter, type the command letters, an “=”

symbol, and then both digits of the desired numerical value.

Example: to change the Master/Slave configuration to Slave,

type MS=00 then click on return.

3. You must set up your terminal emulation program so that it

does not automatically add a line feed (LF) after every carriage

return (CR). The only command format that works is CMD

CR not CMD CRLF.

4. Command MS has to be determined for slave or master.

5. Select RF Channel - Between 01~12 on the 2000-64K

6. The RF Channel must be the same between master and slave.

7. Select transmit clock internal or external depending on your

application.

8. When the power is turned on, the master transmits. The slave

follows the master. When you have a green LED on the ST,

you have a good quality data link between the GINA units.

When both GINA’s link, the transmit and receiver LED’s flash

continuously at approximately 10 flashes per second.

VoiceOperation

1. Both master and slave must have DV command to 00 for voice option.

Data is not active when voice is in use.

2. Connect the handsets to the RJ22 Jack (on the front of GINA) to both

the slave and master. When the voice command mode is set, you can

use the handsets to talk duplex over the link (325 to 4000Hz).
