Address - This option sets the Modbus address of the StarPac II
system. Both the A and B COMM ports have the same address;
therefore, they cannot be hooked together on the same network
and must be connected to different networks. The default
address for a StarPac II is “1” after an initialization. Use the Up
or Dn function keys to select the proper address.
Baud Rate - This option sets the Baud Rate for the Modbus
communications. Available Baud Rate settings are: 1200, 2400,
9600, 19200, 31250, 38400, and 57600. The default setting is
19200 Baud after an initialization. Use the Up or Dn function
keys to select the desired Baud Rate.
Parity - This option sets the Parity for the Modbus
communications. Available Parity settings are: None, Even, and
Odd. The default setting is Odd after an initialization. Use the
NEXT or PREVIOUS function keys to select the proper Parity.
RTU / ASCII - This option sets the communication mode for the
Modbus communications. Available communications mode
settings are: ASCII and RTU. The default setting is RTU after an
initialization. Use the NEXT or PREVIOUS function keys to
select the proper communication mode.
Port Access - This option allows you to control the priority of the
communication ports. A port may be configured so that it can
only be used for monitoring by a remote device. Use the NEXT
and PREVIOUS function keys to select the access from the
following list:
A - R/W B - R/W - Both ports allow read/write access
A - R/W B - RO - “A” port allows read/write access; “B” port
is read only.
A - RO B - R/W - “A” port is read only; “B” port allows
read/write access.
Transmit Delay - This setting controls the time that the
StarPac II system will wait before answering a Modbus request.
The 3.5 character setting provides the best performance for most
systems. Available transmit delays are: 3.5 characters, 50
millisecond, 75 millisecond, 100 millisecond, 150 millisecond,
250 millisecond, 500 millisecond, and 1 second.
LCD Contrast - This option adjusts the viewing angle of the LCD.
Use the Up and Dn function keys to adjust the viewing angle.
