PART 2 – PRODUCTS
2.1	GENERAL
A. 	TKH Security Solutions (www.tkhsecurity.com) is the manufacturer of these rack-mounted fiber optic video duplex data transmitter and receiver cards.
B.	TKH Security Solutions shall produce this product within a quality system in compliance with the ISO-9001.
C.	All equipment and materials used shall be standard components that are regularly manufactured and used in the manufacturer’s system.
D.	All systems and components shall have been thoroughly tested and proven in actual use.
E.	All systems and components shall be provided with comprehensive repair and spare parts replacement. The manufacturer on warranty and non-warranty items shall guarantee the spare parts and the repair.
F.	Use of substitutions shall void the warranty. 
2.2	product Description
A. 	The 9241D series of transmitters/receivers shall transport one NTSC or PAL video signal, one duplex RS-232, RS-422, RS-485, or Manchester data signal, and two duplex option module port signals over one optical fiber. 
B.	The transmitters/receivers shall also provide:
1.	High quality video ≥63 dBw SNR
2.	Uncompressed 9-bit digitizing, oversampling, and digital filtering ensure a very high transmission performance, exceeding the requirements of the EIA RS-250C medium haul specification.
3.	LED indicators to provide an instant overview of the system status.
4.	Compatibility with Network Management System (NMS).
C.	These units shall operate over a wide temperature range and in harsh weather conditions, such as in traffic monitoring, incident management, video surveillance in city centers, and federal and critical infrastructures.
D.	These units shall be built for either rack-mounting or as a stand-alone unit. 
1.	The rack mount models shall be compatible with a 9002, 9008, or equivalent, power supply cabinet.
2.	The rack mount models shall be configurable to stand-alone by using a 9003-2 mini-chassis or equivalent.
2.3	DESign and Performance Criteria
A.	The 9241DT transmitter shall accept a composite video signal in NTSC or PAL format via the BNC video input port. 
1.	This baseband video signal shall be sampled at a 16 KHz rate by an analog-to-digital converter operating with 9 bits of precision. Data signals shall be combined into the bit stream and converted to an optical signal for transmission over the optical fiber. 
2.	For the reverse direction, data shall come into the transmitter via an optical receiver operating at a different wavelength than the transmitter. The received data stream shall be demultiplexed into data for output via the data port and the Option Module Ports.

B.	The receiver shall accept the optical signal and convert it back to a serial bit stream. 
1.	The signal shall be deserialized and converted back into the video and data signals, which are output on the BNC and data connectors. 
2.	For the reverse direction, outputs from the data port and the Option Module Ports shall be multiplexed together, converted to an optical signal for transmission to the transmitter on the second wavelength.
C.	The built-in data port shall be dipswitch-programmable and configurable for Manchester-encoded data, RS-485 2-wire, RS-485 4-wire, RS-422, or RS-232, supporting data at speeds up to 115.2kbps.
D.	The system shall support two Data/Audio Option Modules, each of which shall operate bi-directionally. 
E.	The units shall operate on 6VDC as supplied from the chassis in which they are installed.
F.	The units shall operate through a wide temperate range (-40° to +74° C / -40° to +165° F).
G.	The units shall meet UL/cUL, CE, and FCC part 15 regulatory requirements.
