Controller Cabinet Components
Media Attachment Unit (MAU) - Westinghouse 1C31179G02 provides apoint of attachment for fiber optic cables used to transfer messages over long distances between the PCRR and up to four remote nodes. The module directs messages between the PCRR and one of the four remote nodes at a time as selected, converting signals readable by the PCRR to signals compatible with the fiber optic media and vise versa. The following components comprise the MAU:
— Electronics Module (1C31179) - Houses the Attachment Unit Logic Board (LAU) which provides power for the module and displays LED indication that the fiber optic cables are connected and the Remote Node Controller Module has power.
— Personality Module (1C31181) - Houses the Attachment Unit Personality Board (PAU) which translates signals between the PCRR and the fiber optic media and provides connectors for the fiber optic cables.
MAU Subsystem
Electronic Module | Personality Module | Length of Optical Link1 | کانالها | Optics۲ |
1C31179G01 | 1C31181G01 | Up to 2 kilometers (6,560 ft) | ۲ | 850 nm |
1C31179G02 | 1C31181G02 | Up to 2 kilometers (6,560 ft) | ۴ | 850 nm |
1C31179G01 | 1C31181G03 | Up to 4 kilometers (13,120 ft) |
| 1300 nm |
1C31179G02 | 1C31181G04 | Up to 4 kilometers (13,120 ft) | ۴ | 1300 nm |
1In order not to be required to select extended PCRR time-out periods, it is recommended that you do NOT exceed an optical length of 3.7 km. ۲ An Ovation Controller cabinet MAU MUST use the same type of optics (850 nm or 1300 nm) for each of the remote nodes that it interfaces. An MAU cannot interface both 850 nm remote nodes (using 1C1204G01 Personality modules) and 1300 nm remote nodes (using 1C31204G01 Personality modules.) | ||||
