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.
