INSTALLATION AND OPERATION INSTRUCTIONS
INTRODUCTION
Thank you for purchasing your American Fibertek Series 93285SL singlemode thirty-two channel video multiplexer with bi-directional multi-protocol data. Please take a few minutes to read these installation instructions in order to obtain the maximum performance from this product.
FUNCTIONAL DESCRIPTION
The 93285SL Series units operate as a transmitter / receiver pair for the digital transmission of thirty-two simultaneous NTSC or PAL video signals along with two channels of field configurable bi-directional data over one singlemode fiber optic cable. These data channels may be configured as RS485 data, RS422 data, RS232 data, or Manchester data. The RS485 channel may be configured for 2-wire (half duplex) or 4-wire (full duplex) with or without biasing. Switch selectable internal 120 ohm terminations are available for RS422 or RS485 data.
NOTE: This unit is shipped with Data Channel 1 and Data Channel 2 in the RS485 4-wire configuration. For other configurations, please refer to the DATA MODE section for changes to the default switch settings.
NOTE: This unit is shipped with data terminations off and data bias off for Data Channel 1 and Data Channel 2. For other configurations, please refer to the DATA TERMINATION / BIAS section for changes to the default switch settings.
The RT-93285SL transmitter accepts up to thirty-two video inputs in four groups containing eight videos and multiplexes each group into a high speed serial data stream. The first group’s serial data stream modulates a laser at 1510nm wavelength. The second group’s serial data stream modulates a laser at 1530nm wavelength. This pattern is repeated for group’s three and four using wavelengths 1550nm and 1570nm respectively. A Course Wave Division Multiplexer (CWDM) combines these four wavelengths, along with the forward data wavelength of 1490nm and the return data wavelength of 1470nm, onto a single optical output port for connection to the fiber transmission system. Correspondingly, the RR-93285SL receiver converts the optical signal into thirty-two independent video output signals and two forward data channels while transmitting the two return data channels.
The 93285SL Series product is designed to operate over an optical loss budget range of 0dB to 21dB on 9um singlemode fiber. Refer to the product specification sheet for additional performance data.

INSTALLATION
THIS INSTALLATION SHOULD BE MADE BY A QUALIFIED SERVICE PERSON AND SHOULD CONFORM TO THE NATIONAL ELECTRICAL CODE, ANSI/NFPA 70 AND LOCAL CODES.
RT-93285SL COMPONENTS
The RT-93285SL consists of the following components:
1) RT-980-1510 1) RT-980-1550 1) SR-20 1) PSR-2
1) RT-980-1530 1) RT-980-1570 4) PCSC/UPC-0.3 3) BPS-2
1) MTX-CWDM-8-MPD The individual 980 series video rack cards that make up the RT-93285SL are combined in a
rack mount configuration using the SR-20 subrack. Please refer to the instruction manuals for the SR-20 and the PSR-2 for information on the installation of the subrack with its power supply. The individual 980 series rack cards can slide into any of the open slots in the SR-20 subrack, however, the recommended configuration is shown below. This configuration starts with the lowest wavelength card, the RT-980-1510, next to the PSR-2 power supply and ends with the highest wavelength card, the RT-980-1570, at the left side of the rack. Following this configuration allows the fiber port on the back of the 980 series card to best line up with its associated port on the CDWM unit. Use a small screwdriver to push and lock the ¼ turn fasteners into place. The Multi-Channel Digital Video CWDM that optically multiplexes the four video rack cards used in the RT-93285SL is labeled MTX-CWDM-8-MPD. It should be mounted directly below its corresponding SR-20 subrack with a ½ RU space between the two components. To maximize the performance and life of the system, installing a fan above the SR-20 subrack is recommended to pull air up across the RT-93285SL components.

RR-93285SL COMPONENTS
The RR-93285SL consists of the following components:
1) RR-980-1510 1) RR-980-1550 1) SR-20 1) PSR-2
1) RR-980-1530 1) RR-980-1570 4) PCSC/UPC-0.3 3) BPS-2
1) MRX-CWDM-8-MPD The individual 980 series video rack cards that make up the RR-93285SL are installed in a
manner similar to the RT-93285SL (see drawing below). The Multi-Channel Digital Video CWDM that optically demultiplexes the four video rack cards used in the RR-93285SL is labeled MRX-CWDM-8-MPD. Mounting procedures and recommendations should follow those used for the RT-93285SL.

POWER SOURCE
Power to the 980 series rack cards is supplied by the subrack. Please refer to the SR-20 and PSR-2 instructions for further details.
Power for the CWDM units is generated by an internal power supply which accepts universal line voltage. Any mains supply from 100 to 240 VAC, 50 to 60 Hz, may be used without modification or adjustment. A universal power connector is provided on the rear of the unit to facilitate connection to the power mains.
POWER CONNECTION
Power is supplied to the individual 980 series units via a four finger backplane connector. The individual components can be inserted into the subrack or removed from the subrack with power applied to the backplane. Please refer to the SR-20 and PSR-2 instructions for details.
The CDWM unit is supplied (in the US and UK only) with a three conductor power cord. The “ground” conductor is directly connected to the chassis.
