valid data
When the XEG42 is receiving without incoming signals, a request for transmitting data nan be made by
pulling the TXRQ dawn to L,
Upon detecting the TXRQ input. the KEG-42, after checking the lodr-iip or the frequency synthesizer,
switches itself into transmit made. Havmg established the transmit state an ID (by manufacturer’s option)
is sent out, and CTS is swnched to L permitting the data input for transmission. '
The data through TXDT is valid only after the CTS has gone L and any dala input while the CTS is H
will not be transmitted
Precautions for data transmission/reception
1) ID Reception
Due to automatic transmission nf an ID at the beginning of each transmissmn. the received data will
have an ID at the beginning,
2) RXDT, SYNC
Because a differential demodulator is employed for the demodulation of primary modulatim'i‘ clock like
pulses or non logical data may come out from the RXDT while no signal is received.
To come around this problem, it is highly recommended that a receiving data is acnepied after checking
the synchronization Via the SYNC line,

' The R58] is output from the limiting amplifier of the LF. stage in current-variant state, and is
converted to voltage by a 3 k-ohm resustor, followed by an isolation circuit inside the XEGdZ. The
outyut impedance for the R851 terminal is lOk-ohm, therefore the output should be connected
with a high-impedance buffer amp,

may not cause harmful lnIlrIevence. and (2) this device must accept any linemen» received, mcludmg interference [hat may
cause undesired operation
FCC ID: EUGXBSQT
WARNING:
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed
to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses, and can radiate radio frequency
energy. and if not installed and used in accordance with the instructions, may
cause harmful interference to radio or television communications. However.
there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged
to try to correct the interference by one or more of the following measures:
. Reorient or relocate the receiving antenna.
. Increase the Separation between the equipment and receiver.
0 Connect the equipment into an outlet on a circuit different from that
to which the receiver is connected.
- Consult the dealer or an experienced radiofl'V technician for help,
This equipment has been certified to comply with the limits for a Class B
computing device, pursuant to Part 15 of FCC rules. Only peripherals (computer
input/output devices, terminals, printers, etc.) certified to comply to the Class B
limits may be attached to this computer. Operation with non—certified peripherals
is likely to result in interference to radio and TV reception.
INFORMATION TO USER:
Any changes or modifications not expressly approved by the party responsible
for compliance could void the user's authority to operate this equipment.
The use of shielded cables for connection to the TV-F’CI TVIFM Tuner Adapters'
audio composite video, S-Video, RF Input Video in-put and FM Stereo Input is
required to assure compliance with FCC Class B regulations.
