Changing the RF channel and/or the RX4000 Baud rate.
The RX4000 has an internal programming switch block located on the circuit
board. Changing the default RF channel or baud rate requires accessing and
changing this programming switch.
To access the internal set-up switch:
First, remove all com and power connections, then remove the snap-on cover
to access the set-up switch. To remove the cover, squeeze the bottom sides
near the ends, and lift the top cover, it will un-snap. With the cover removed,
Figure 1 shows the internal location of the 10-position DIP switch used for set
up. Switch positions 1 through 5 set the RF channel, (ref Table2). Switch
positions 6, 7 and 10 are factory use and should remain in the ON position
for normal operation. Switch positions 8 and 9 select the baud rate.
Some notes:
The default RF channel is 07. Changing the RF channel requires that the
remote transmitters used with the RX4000 “log on” to the selected channel.
Therefore you must inform users of the channel number you have selected so they can re-program their remotes to operate on the
same RF channel selected.
The default baud rate is 19.2K. USB cables over 15 feet should not be used when the Baud rate is set higher than 19.2K
Changing the BAUD RATE:
Table 1
shows the switch settings and resultant baud rate. The initial factory setting
is 19.2K baud.
DIP switch positions 8 and 9 are used to set the baud rate of the RX4000.
Reference figure 1 to locate the DIP switch, and table 1 for setting the desired baud
rate.
Changing the RF Channel:
Table 2
shows the numeric value of the 31 selectable channels. The
switch setting of all on should not be used. In order for the students’ clickers
to operate on the same RF channel as the RX4000, the selected RF
channel must be published, or otherwise be made known to the students in
the classroom where the RX4000 is being used. A description of Student
“log-in” for the classroom RF channel is provided in the clickers instruction
manual.
