The DSM COMM (Serial Communications) Connector
The module’s front panel contains a single RJ-11 connector for serial communications, labeled
“COMM”. It is used to download firmware updates to the DSM module from a personal computer
running the GE Fanuc PC Loader or Win Loader utility software. (See Appendix F for details.)
This serial COMM port connects to the personal computer’s serial port and uses the GE Fanuc
SNP protocol and the RS-232 serial communications standard. The baud rate is configurable
from 300 to 19,200 baud. The COMM port is configured using the VersaPro 1.1 (or later)
Configuration Software.
A 1-meter cable, IC693CBL316, is available from GE Fanuc to connect the COMM port to a
personal computer. This cable uses a 9-pin female D-shell connector for the computer side and an
RJ-11 connector for the DSM314.
If a longer cable is used, the maximum recommended
length is 50 feet.
