UIC cable
The UIC cable is the term used to describe the cable that is usually coupled within the intercar connections of passenger trains and is used for data transmission .
Standard UIC 568
The 13-core cable with plug according to UIC 568 is a connection cable standardized by the UIC , with which data and switching commands are exchanged between the locomotive and the passenger cars of a train . These are, for example, announcements, control of the train destination display or the door control .
Locomotives that comply with the standard usually have two sockets on each end , and the cables are routed from car to car.
Further development of UIC 558
Attempts have been made to use this cable for a complete communication bus ( Train Communication Network , TCN), but it has been shown that for the sake of downward compatibility when used with non-converted cars, an 18-pin cable is preferable. This led to the development of the UIC 558 cable. The additional contacts 14 and 15 are used by various railway companies for the side-selective door control and the contacts 17 and 18 as Wire Train Bus (WTB) of the TCN. The cores number 17 and 18 must be designed as a twisted pair with a shield. A 13-pin plug can be connected to an 18-pin socket and transmits the signals of the 13-pin version.
Standardized functions, assignment of the wire pairs
| Wire no. | function |
|---|---|
| 1/2 | Sound transmission to power amplifiers, 2 V ~ 100… 8000 Hz |
| 3- / 4 + | Continuous signal 24 V = speech connection to the engine driver, modulation maximum 2 V ~ 100… 5000 Hz |
| 3 + / 4- | Speech connection to the control center, modulation maximum 2 V ~ 100… 5000 Hz |
| 5 + / 6- | Continuous signal 24 V = switch on loudspeaker system |
| 7 + / 8- | Continuous signal 24 V = priority for announcements (interrupts music or local loudspeaker feed) |
| 9 + / 12- | Impulse 24 V = door closing |
| 10 + / 12- | Pulse (<2 s) 24 V = lighting on |
| 11 + / 12- | Pulse (<2 s) 24 V = lighting off |
| 13 | Cable shielding for all wires |
| 14 + / 12- | Impulse (<2 s) 24 V = release doors on the left |
| 15 + / 12- | Impulse (<2 s) 24 V = release doors on the right |
| 16 + / 12- | Closed circuit, feedback all doors closed |
| 17/18 | Twisted data line (train bus) for WTB according to UIC 556 |
| S. | Screen for cable 17/18 |
Non-standardized functions, application in individual countries
| Wire no. | function | user |
|---|---|---|
| 9 + / 12- | Continuous command 24 V = keep doors (permanently) blocked - system TB0 | DB |
| 9- / 12 + | Pulse (<30 s) 24 V = bridge emergency brake - DB-ep brake | DB, ÖBB |
| 10- / 12 + | Pulse (<20 s) 24 V = ep brakes - DB-ep brakes | DB, ÖBB |
| 11- / 12 + | Pulse (<60 s) 24 V = ep-release - DB-ep-brake | DB, ÖBB |
| 9/10 | Continuous signal 2 V ~ 1 kHz from the locomotive, pressing the emergency brake causes this signal to short-circuit | DB, ÖBB |
| 7/9 | 6 V ~ 9600 Hz channel for time-division multiplexed locomotive control | SNCF |
| 10/11 | 6 V ~ 19200 Hz channel for time-division multiplex locomotive control | SNCF |
| 10/11 | <950 mV 69.6, 96, 120 and 165 kHz channels for time-division multiplex push-pull train , double-traction or multiple-traction control (ZWS, ZDS, ZMS) | DB |
| 7 + / 12- | Pulse 24 V = direction indicator for triggered emergency brake | SNCB |
| 7 + / 8- | Continuous signal 24 V = announcement outside loudspeaker | ÖBB |
| 9/10 | Eil-Net night transport car | VR |
| 11/12 | <16 V ~ Train-Net IC car | VR |
| 14 + / 12- | Continuous signal 24 V = blocking doors on the left (inverse to standardization, ÖBB remote control concept) | ÖBB |
| 15 + / 12- | Continuous signal 24 V = blocking doors on the right (inverse to standardization, ÖBB remote control concept) | ÖBB |
| 14/15 | Specially twisted as data line (train bus) for WTB according to UIC 556 (DB special assignment, single-type sets) | DB |
| 16 + / 12- | Closed circuit, feedback "at least one door open" (inverse to standardization, single-type sets) | DB |
| 17/18 | Twisted data line (train bus) for IBIS / passenger information system (DB special allocation of single-species sets) | DB |
| 17/18 | Twisted data line (train bus) for WTB according to ÖBB remote control concept, not compatible with UIC 556 | ÖBB |
