Dip Switch Information
There are two dip switches located on the controller board, Switch 1 and Switch 2.
Switch 1
Switch 1 is used to configure the display - RS485 echo enable, baud rate settings,
and display size.
•
Position 1 enables or disables the echo function.
Enabling the RS485 echo function allows any packets that come in on COM
0 (download, RJ-12 port), COM 1 (RS-232, TB3 port), and the Ethernet
TCP/IP port to be sent out the RS485 port. This allows Ethernet TCP/IP and
other communication protocols to be converted to RS485 by a single P92 or
P94 and then sent out to multiple RS485 networked displays.
•
Positions 3 and 4 set the baud rate. (See page 13 for default positions.)
If both switches are off, the baud rate can be set via the InView Messaging
software. The dip switches take priority over the software setting. If the baud
rate is set to 19,200 using the software (positions 3 and 4 set to off) and then
set to 9600 using switch 1 (position 3 on and 4 off), the baud rate would
then be 9600. Also, once positions 3 and 4 are used to set the baud rate and
then they are switched off, the baud rate setting will remain until it is
changed by software or a different dip switch setting.
•
Position 5 is used to set the display size. This is set by the factory.
•
Position 6 is used to turn on diagnostics.
•
Position 7 disables download message.
TIP
Only enable the echo function on one P9x display.
