Basler Power-I/O Cable RS-422 M8 6p/open#
Introduction#
The Power-I/O RS-422 cables feature an M8 6-pin connector (camera side) and an integrated signal converter.
The key feature of this board is that it is able to convert RS-422-differential signals to single-ended signals compatible with the GPIO and opto-coupled input ports of a Basler ace 2 or racer 2 S camera.
In addition to RS-422, the signal converter for input line 1 accepts 5 V TLL and 24 V PLC signal levels via separate wires.
Technical Data#
Info
The cable is suitable for the following camera models: Basler ace 2 or Basler racer 2 S cameras.
| Order Number | Cable Length |
|---|---|
| 2200002274 | 10 m |
Cable Drawing#
CAUTION – Fire hazard may cause burns or damage the camera.
The cable is designed for a total current of 1 A or less. Exceeding this limit can present a fire hazard and a risk of personal injury due to overheating. Basler recommends using a fuse or a limited power supply to ensure staying within the safe operating limits.
CAUTION – Using unsuitable cameras may damage components.
The Power-I/O Cable RS-422 M8 6p/open was specially designed for use with a Basler ace 2 or a Basler racer 2 S camera. If you use the cable in combination with other camera models, even if the connector fits, this can damage the signal converter circuit, the cable, or the camera.

| RS-422_p (3) | Black | Input line 3 | GPIO |
Note
- Due to the integrated opto-coupler, input line 1 offers only limited speed. If you require high speeds in your applications, Basler recommends to use input line 2 or input line 3 for external triggering. Details:
- TTL In, PLC In, and RS-422 (1) drive an opto-isolated low-speed camera input.
They are best suited for signals with a switching frequency of 10 kHz or less. - RS-422 (2) and RS-422 (3) are for general-purpose full-speed inputs.
- TTL In, PLC In, and RS-422 (1) drive an opto-isolated low-speed camera input.
- Each of the wires for VCC, TTL In, and PLC In is twisted with a corresponding GND wire.
For best immunity against electromagnetic fields, all GND wires should have a low-impedance connection to the same GND point. - The signal converter is powered via VCC. VCC must therefore be connected to a power source, even if the camera is powered via Power over Ethernet (PoE) or Power over CoaXPress (PoCXP).
- TTL In, PLC In, and RS-422 (1) are connected in a ‘wired-or’ configuration. Unused signals must be left unconnected. TTL In and PLC In can optionally be connected to GND for best immunity against electromagnetic interference.
- To protect the signal converter from damage in case of a short circuit, Basler recommends a VCC voltage of 12 V.
However, it is safe to operate the converter cable and camera with a VCC voltage of 24 V.

DC Characteristics#
The following table shows the DC (direct current) characteristics.
| Description | RS-422 | TTL 5 VDC | PLC 24 VDC |
|---|---|---|---|
| Minimum Input Voltage | - 7 VDC | 0 VDC | 0 VDC |
| Nominal Maximum Input Voltage | 12 VDC | 24 VDC | 24 VDC |
| Absolute Maximum Input Voltage | 14 VDC | 30 VDC | 30 VDC |
| Maximum Low-level Voltage Threshold | -200 mV diff | 1.4 VDC | 8.4 VDC |
| Minimum High-level Voltage Threshold | 200 mV diff | 2.6 VDC | 10.8 VDC |
NOTICE – Voltages outside of the specified range may damage the camera.
The absolute maximum input voltage of 30 VDC must never be exceeded, not even for a short time. Doing so may damage the camera and voids the warranty.
Note
- The threshold voltages for TTL In and PLC In reflect the camera's threshold voltages, which are increased by the forward voltage of the Schottky diodes in the 'wired-or' circuit.
- RS-422 threshold voltages refer to the differential voltage between RS-422_p (X) and RS-422_n (X), with ‘X’ for the input line.
