APPENDIX I. RF100/200 RADIOS
I.1 RADIO DESCRIPTION
The RF100 and RF200 are obsolete radios
used in Campbell Scientific's RF applications to
transmit and receive data blocks. The radios
are shipped from Campbell Scientific secured
on a mounting bracket designed to fasten on
the top of the RF modem (see Figure I-1). See
Appendix F for compatibility information.
The mounting bracket also supports a BNC
Jack connector from the radio. The coax cable
that is required to connect the radio to its
antenna should be connected to the radio at this
BNC connector. See Section 3.3 for more
information on the antenna cable.
The RF100/RF200 Radios are connected to the
RF modem by a special radio cable. The first
10-pin connector on this radio cable has a red
and black wire coming out of the connector.
This is the 10-pin connector (labeled "radio")
that should be connected to the radio. The red
and black power wires should be connected to
12 V and Ground respectfully. The second 10-
pin connector (labeled "RF modem") should be
connected to the RF modem.
I.2 RADIO SPECIFICATIONS
The RF100/200 radios were manufactured by E.
F. Johnson. Campbell Scientific modifies the
radios to work with the RF95 Modem..
