2080 Optical Signal Processor(OSP) Card
Specifications:
Signal Coding:
The 2080 shall be capable of
receiving, decoding, and prioritizing the Emergency and Transit
signals transmitted by TOMAR 2060 identifying emitters. The 2080
shall be configurable via a jumper on the control module, to accept
or reject older non-identifying optical signals.
Signal Acquisition Time:
Typical signal acquisition
time shall be approximately 2.5 seconds. Acquisition time will vary
depending upon the number of identification codes present
simultaneously and on the density of optical noise.
Simultaneous Signals:
Each signal processor module
shall be capable of receiving and decoding up to 10 coded signals
simultaneously. Additional simultaneous signals will be
ignored.
Range:
2500 feet maximum adjustable down to 300
feet in 255 steps for each signal band.
Range Adjustment:
Range adjustment shall be
accomplished via front panel switches and emitter.
Maximum Number of Codes:
The 2080 shall respond to
any of the 65,000 unique identification codes available in each
signal band.
Priority Determination:
Signals in the Emergency
signal band shall be given priority over signals in the Transit
signal band. Signals in the same band shall be serviced on a
first-come, first-served basis.
Output Signals:
The 2080 shall provide four
optically isolated output channels for placing calls on the traffic
controllers preempt inputs. All output signals shall comply with
NEMA signal level definitions.
Max
Call Timer:
Each channel shall be equipped with a MAX CALL
TIMER which will disable a channel’s response to an emitter code
should that code remain within range for more than 5 minutes. Once
the emitter is shut off for 5 seconds or more the channel shall
again respond to that emitter.
Electrical Requirements:
120VAC 50/60
Hz.
Temperature Range:
-40 degrees Celsius to +75
degrees Celsius.
Transient Protection:
Input power shall be MOV and
fuse protected from line transients.
Fusing:
Input power connections shall be fused at
1/2 amp. to prevent cabinet wiring damage in the event of an
electrical failure.
