InView System Connectivity 2-5
Position 1 enables or disables the echo function.
When you enable the RS485 echo function, this 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 2706-P92 or 2706-P94 and then sent
out to multiple RS485 networked displays.
Positions 3 and 4 set the communication rate.
Refer to page 2-6 for default positions.
If both switches are off, the communication rate can be set via the
InView messaging software. The dip switches take priority over the
software setting. If the communication rate is set to 19200 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 communication rate is 9600.
Also, once positions 3 and 4 are used to set the communication rate
and then they are switched off, the communication rate setting
remains 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.
Switch 2
Switch 2 is used to set the serial address of the display. Position 1 is
the LSB of the address and position 8 is the MSB of the address.
If position 1 is on and all other positions are off, the display address is
1.
If position 8 is on and all other positions are off, the display address is
128.
If all positions are set to off, the serial address is set using the InView
messaging software.
TIP
Only enable the echo function on one
2706-P9x display.
