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-94885SL transmitter accepts up to forty-eight video inputs in six 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. -
Page 4: Installation
1) RT-980-1610 1) MTX-CWDM-8-MPD The individual 980 series video rack cards that make up the RT-94885SL 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. - Page 5 The individual 980 series video rack cards that make up the RR-94885SL are installed in a manner similar to the RT-94885SL (see drawing below). The Multi-Channel Digital Video CWDM that optically demultiplexes the six video rack cards used in the RR-94885SL is labeled MRX-CWDM-8-MPD.

The location of a video input to the RT-94885SL will be mirrored as a video output at the RR- 94885SL. For example, the Channel 2 video input on the RT-980-1550 will become the Channel 2 video output on the RR-980-1550 after traveling across the fiber infrastructure. - Page 7 (data out) wires and which two wires are the receive (data in) wires. MTX-CDWM-8-MPD or MRX-CDWM-8-MPD Please note that Data In on the RT-94885SL becomes Data Out on the RR-94885SL after going across the fiber. The reverse flow follows the same orientation.

Page 8: Data Mode And Data Termination/Bias Switches
DATA MODE NOTE: This unit shipped with Data Mode switches in the RS485 4-wire position. For other configurations of data channel 1 or data channel 2, please refer to the drawing below for changes to the default switch settings. These configuration switches are located on the front of the unit and can be modified without opening the unit. - Page 9 DATA TERMINATION / BIAS (cont.) RS485 4-wire termination / bias switch settings: RS485 2-wire termination / bias switch settings: NOTE: An explanation of termination and bias requirements for various data formats can be found at the end of this manual.

Page 14: Data Termination And Offset Bias Requirements
DATA TERMINATION REQUIREMENTS RS232 Data Signals The RS232 interface standard is a point to point transmission protocol for digital signals. It allows for a single transmitter device communicating to a single receiving device. This configuration is mirrored in the opposite direction to create one bi-directional data path. Devices using this protocol have terminating resistors built into their data path. -
