RF Serial Pin-outs

Base Station to Host Pin-outs
The Base Station is connected to a PC with one of the following cables:
F34 DB25 Null Modem Cable
These are the pin-outs for Cable F34, a DB25 Female to 8 pin modular RJ45 with pins 2 and 3 crossed, used
for a Base connected directly to a 25 pin male host serial port.
Modular Pins 5-8 are connected to DB25 pins 5,6,8,4 but not used by the RF Base.
If you are planning to use a serial extension cable of 80 feet or more, you need to open the DB25 shell of
our cable and be sure that only pins 1,3,2, and 7 are connected. All others should be cut. This is necessary to
keep Windows from following noise transitions as handshaking transitions that can severely degrade the
application or even crash Windows.
F36 DB9 Straight Cable
These are the pin-outs for Cable F36, a DB9 Female to 8 pin modular RJ45. This cable is used to connect
the Base to a 9 pin Male host serial port.
If you plan on building your own extension cables, you must use well shielded cable and you cannot use
twisted-pair cable. You can order custom length RS-232 extension cables from Global Computer Supplies -
phone 800-845-6225, part number ZCC4912X. Many other companies sell 10 ft., 25 ft., and 50 ft. DB9
Extension Cables including Radio Shack.
