Beijer Cables Troubleshooting

It's not possible to power terminal with cable over 10m
?
The CAB19/10m and higher (and CAB18 higher than 15m) does not have the power supply in the cable. The reason is that the voltage drop is too large in the cable.
?
The FX Mini DIN connector has only one +5V supply out and therefore we cannot increase the area of the cable as much as needed (the impedance in the cable will be too large).
?
For the CAB18 you have 2 +5V pin out and therefore we can increase the cable area so we can power the terminal up to 15m.

SC-09 cable CE-Certification
We cannot provide any CE certification for the SC-09 programming cable.

Serial printer cable

Signals for serial printer
- 232 Port on terminal Port on serial printer
- 2 RxD > TxD
- 3 TxD > RxD
- 5 SG (0v) > (0v)
- 7 RTS > CTS
- 8 CTS > RTS
If the printer has a buffer, RTS and CTS are not needed.

Why can I not download my project?
To use the CAB 6 you must make sure that your terminal has a +5 VDC supply between pin 14 and 7 on the RS422 port.
?
If not, the terminal cannot power the electronic board in the RS422 connector.
?
Why does my communication not start?
If the communication starts with ex the CAB 1 cable (Cimrex) or the programming cable for the S5 system (Exter) make sure that your terminal has a +5 VDC supply between pin 14 and 7 on the RS422 port.
?
If not, the terminal cannot power the electronic board in the RS422 connector.

Detailed info on CABDC24-5V
Problem
1. What is the short-circuit voltage on the 5V DC output?
?
2. What is the voltage fluctuation on the 5VDC output (-xxxV ... + xxxV)?
Solution
1. The output voltage in the short circuit condition is a "Hiccup" state. The value of the resistor R21 (0,27 Ohm) sets the max output current limit.
?
2. Voltage fluctuation is +/- 6% (+/-300mV)
