Figure 33. Typical Connection for Unidirectional RS-232 Insertion
1. Connect the control system to the Remote RS-232 port on the IN1804 rear panel.
2. Connect the TP cable from the IN1804 RJ-45 Out connector to the DTP input of the
endpoint.
3. Connect the output of the endpoint to the device to be controlled.
4. Connect a serial cable from the Over DTP RS-232 port of the twisted pair receiver to
the device to be controlled.
Entering SIS commands for RS-232 insertion
The following SIS command enables insertion of commands into an RS-232 datastream:
E
+snds
X5&
*
X3# }
<command being sent>
X3#
= number of characters in the command
X5&
= TP port number
The unit sends the command when it detects that the specified number of characters (
X3#
)
have been entered.
You can enter the SIS command through any means: Ethernet, USB, or an RS-232
connection. Any RS-232 command can be sent via this method. Typically, however, this
command would be sent through an RS-232 connection to the Remote port on the IN1804.
In the following input selection example, 9 is the TP port and 13 is the number of characters
in the command %1Bpoweron%0D (to select input 1):
E
+snds9*13
}
%1Bpoweron%0D
