Carrier Frequency
The FASTRAK may be configured with any one of four discrete carrier frequencies to allow
simultaneous operation of up to four systems in close proximity. Carrier frequencies are selected via color
coded Frequency Select Modules (FSM). These frequencies are:
Reference #
Frequency Color Code
1
8013 Hz Black
2
10016 Hz Red
3
12019 Hz (Std) Yellow
4
14022 Hz Blue
5
14022 Hz Green TX1
6
12019 Hz White TX1
A colored dot can be found on the FSM, on the end closest to the connector and on the back panel of the
FASTRAK SEU as it comes from the factory. FSMs different from the standard can be specified by the
user at time of order or can be purchased for a nominal fee at any time. Field installation of a FSM should
prompt user change out of the SEU color dot in order to facilitate easy identification among multiple
FASTRAKs.
RS-232 Interface
RS-232C serial port with software selectable baud rates of 1200, 2400, 4800, 9600, 19200,
38400, 57600 and 115200; ASCII or Binary formats. The factory default setting is 115.2K baud.
An RS-422 port is available as an optional serial port in lieu of the RS-232 at the same baud
rates.
USB Interface
USB (Universal Serial Bus) has become the predominant interface standard. It removes
transmission speed limitations (due to maximum baud rate) and allows transmission speeds up to
12 Mbps. USB utilizes differential signaling for better signal quality and noise rejection and
therefore allows the use of longer communication cables between the host computer and the
FASTRAK system.
Operating Environment
Large metallic objects, such as desks or cabinets, located near the transmitter or receivers may
adversely affect the performance of the system. Many walls, floors, and ceilings also contain
significant amounts of metal.
Operating Temperature
10
°
C to 40
°
C at a relative humidity of 10% to 95% non-condensing.
