Ensemble Epaq Hardware Manual Installation and Configuration
2.5.3. RS-232 Interface
Connecting the RS-232 port to a user’s PC requires a standard 9-pin cable (not a null modem). If the /RS232-
1 option has been purchased, an additional RS-232 port will be located at the J100 connector. The additional
RS-232 port will be identical in form and function to the standard RS-232 port.
This interface is also jumper configurable for RS-422 or RS-485 communication; refer to the Figure 2-33 for
jumper configuration.
