6 CLS-420/420 Plus WLAN Installation Instructions
Establishing Communication With the 420
The option card has two TCP Ports that can be used to communicate. Default is TCP Ports 10001 (Port 1) and
10002 (Port 2). These numbers can be changed in the option card, if needed. Port 1 and Port 2 refer to the physical
connection on the option card. If installed as instructed, J2 (Port 2) is connected to either the EDP or PRN port on
the420 indicator. J1 (Port 1) was used for configuration. If using Port 1 to talk to the ‘other’ RS-232 port on the
420, it can be wired it at this time.
The default RS-232 communications settings on the option card are 9600, 8N1, and should match the default
settings in the 420. If not, make the necessary changes in the 420, or the option card Channel 1 or 2 (port 1 or 2) so
they match.
To open a connection, start the PC Communications software and open a TCP/IP connection to the IP address
assigned to the card (with the static IP that was configured, or the DHCP IP assigned by the network), and the port
number for the ‘Port’ on the option card to be talked through (by default, this will be 10002, or Port 2).
Once open, communication is established to the 420 the same as if wired to an RS-232 connection.
Other Options
By default, it will take an external device or program to establish a communications connection to the option card
in the 420. However, the option card is also capable of initiating the connection to another device or PC listening
on a port.
In the serial settings for the RS-232 channel are using, there are settings to open an active connection. By default,
this is off. To use the 420 to open a connection, the active connection parameter can be set to something other than
None, such as “With Any Character,” the remote host IP and Port values will have to be set. This setting will open
a connection to a remote host as soon as any character is sent from the 420 to the option card. This could be useful
for printing to a remote printer, streaming to a remote display, or sending data to a PC program.
There is wide variety of possible configuration settings, refer to the user guides include on the CD, or call our
technical or sales support staff with the particular application and questions.

Important
Use the torque pattern shown in Figure 5 to prevent distorting the backplate gasket. Torque screws to 15
in-lb. (1.7 N-m).

Important
Torqued screws may become less tight as the gasket is compressed during torque pattern, therefore a
second torque is required using the same pattern and torque value.
