4.2.3 Set Com 2 Baud Rate
The “SET COM3 BAUD RATE” menu allows setting the communications baud rate for communications port
2. The Baud rate can be set to 4800, 9600, 14400, or 19200. The normal Baud rate is set to 9600 Baud, and
should not be changed.
From the Main Menu use the “u” or “v” keys to move to the “SET COM2 BAUD RATE” menu item and
press “ENTER” to enter the “SET COM2 BAUN RATE” menu. The display will change to “BAUD RATE
COM 2:” followed by the current Baud Rate setting. Use the “u” key to increase the Baud rate, and the “v”
key to decrease the Baud rate. When the appropriate Baud is selected, press the “ENTER” key to accept the
number. The display will return to “SET COM2 BAUD RATE”
Press the “PROG” key to exit the menu and use the “u” or “v” keys to move to the next or previous menu
item, use the “PROG” key to exit the Main Menu, or allow the unit to time out and the unit will return to
Normal Operation after about 15 seconds.
4.2.4 Setup Channel Data
This menu item allows the setup of parameters necessary for monitoring each device. The parameters set for
each channel should match those of the device that the channel is monitoring.
From the Main Menu use the “u” or “v” keys to move to the “SET CHANNEL DATA” menu item and press
the “ENTER” key to enter the “SET CHANNLE DATA” menu. The LCD will display the current parameters
for Channel 1. In example:
CHANNEL
1 DATA: DECIMAL POINT:0
SLAVE ID:01 RANGE:100
REGS TO READ:13 TYPE:PPM H2S
READING REG:0 RTO:1000 IPD:150
These parameters must be set correctly for each sensor or DA4 module that is connected to the unit. Use the
“u” or “v” keys to move through the parameters, setting the appropriate values for each parameter as described
below. When the Blinking Cursor is positioned over the colon (“:”) of the parameter to be changed, use the
“ENTER” key to make changes to the parameter. The parameter will be displayed in brackets “[ ]” to signify
the ability to change that parameter. Once the correct parameter has been set, use the “ENTER” key to accept
the change. The Cursor will change back to a Blinking Cursor, and the arrow keys can again be used to move
through the parameters.
When the Blinking Cursor is at the end of a set of parameters for one channel, the “v” key will move the
cursor to the next channel’s set of parameters. Likewise, when the Blinking Cursor is at the beginning of a set
of parameters for a channel, the “u” key will move the cursor to the previous channel’s set of parameters.
Note: The parameter screen(s) will not move from the last channel to the first channel, or from the first
channel to the last channel by use of the “u” or “v” keys. The last channel available is determined by the
number of channels set active via the “SET # OF CHANNELS” menu.
SLAVE ID (Slave ID Number):
This is the Modbus™ Hexadecimal address assigned to the sensor and or DA4 Modules connected to the unit.
This number is adjustable from 01 to 7F hex by use of the “u” or “v” keys, and should match the appropriate
device. Each device’s Modbus™ address must be unique. When working with the DA4 modules, it is
important to realize that the DA4 may have 4 analog sensors attached to it, but the DA4 Module has one
Modbus™ address, and that address must be unique. Normally these Modbus™ addresses start at 02 hex and
sequentially increment to the highest address used.
