GINA MODEL 2000-64K

GINA Model 2000-64K is a stand-alone, high frequency data transceiver using
spread spectrum technology . GINA 2000-64K capabilities include
synchronous data transmission at speeds to 64 Kbps at the data port with EIA 562/
RS-232, EIA530/RS-530, and V.11 (V.35) interfaces. GINA 2000-64K receives
and transmits data in the frequency range of 2.404 - 2.478 Ghz at air speeds of
up to 186 Kbps. Communicating at this speed allows GINA 2000-64K to be a
full (TDD) duplex link. GINA can be configured to be used as a point-to­point communication device. GINA 2000-64K contains a packet controller
module with a custom communication protocol that provides communications
handshaking, cyclic redundancy checking (CRC), packet sequencing, and
flow control.

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-232 Command Control Data Port. Used for programming

during GINA setup. This port communicates at 9600 kbps

asynchronous only .

NOTE: GINA only operates with the handset supplied with the unit.
Do not attempt to use a standard telephone handset.
