Etel DSC Series Hardware Manual

32 DSCDP Hardware Manual
ETEL Doc. - Hardware Manual # DSCDP / Ver G / 6/1/11
Caution: To respect the 'Standard safety of information technology equipment' standard (EN
60950, UL 60950), the serial cable used between the controller and the computer must
have an insulation protection (except if the auxiliary and power input are lower than 50
VDC).
If you want to manufacture your own RS232 communication cable, you should wire it as shown below:
3.3.4 Connector JC4: Download key
This connector is used for the download key. If the DSCDP does not switch to 'wait for program', there is an
hardware override possibility to force this mode. To do so, plug the download key into the JC4 connector, switch
off and on the controller, and the DSCDP will switch to 'wait for program' in order to download a new firmware
in the DSCDP.
A download key is a 8 pins RJ-45 male connector, with a bridge between pins 5-6:
Remark: (*): these signals are only available from the DSCDP3xx-xxxF version and later.
The download key of the DSCDP is compatible with the DSC2P, DSC2V and DSCDL key.
Refer to the corresponding 'Operation & Software Manual' for more information about the STI
and FTI.
RJ-45, 8 pins, female
DOWNLOAD KEY Pin # Signal Function
1 SIN M1(*) Indicates when the analog encoder's sine signal of motor M1 goes through 0 (TTL signal)
2 COS M1(*) Indicates when the analog encoder's cosine signal of motor M1 goes through 0 (TTL signal)
3 SIN M2(*) Indicates when the analog encoder's sine signal of motor M2 goes through 0 (TTL signal)
4 COS M2(*) Indicates when the analog encoder's cosine signal of motor M2 goes through 0 (TTL signal)
5 DWL + Sets the DSCDP to 'wait for program' (download) if connected to 0V
6 GND Auxiliary supply output (0V)
7 SLOW INT.(*) STI (Slow Time Interrupt) signal (2 kHz) active on a low state (TTL signal)
8 FAST INT.(*) FTI (Fast Time Interrupt) signal (18 kHz) active on a low state (TTL signal)
