Baud rate is defined as number of bits per second. The available selections are 1200, 2400, 4800, or 9600.

This Delay in milliseconds is used to allow hand shaking between the PC and the Flow Computer. The PC
will hold the RTS line high for the specified Transmit Delay time. After that time expires the data stream
will begin transmitting. Transmit Delay is applicable regardless of the type of communication with the
Flow Computer (RS-232 or RS-485).
This function can be very useful, especially when using a half-duplex RS-485 port; it allows the RS-485
port to turn off. A delay of 50 milliseconds is normally sufficient.
RTS can also be used as transmit line to printer. (RTS to Pin2, Common to Pin7)
Flow Computer Communication Set Up
U n i t I D N u m b e r
The Unit ID Number is used strictly for communication purposes; it can take any value from 1 to 247.
Note: Do not duplicate the Unit ID number in a single communication
loop! This situation will lead to response collisions and inhibit
communications to units with duplicate ID numbers.
Only one master can exist in each loop.
Po rt # 1 Mo d b u s T y p e
Note: this parameter must be set the same for both the PC and the
Flow Computer for communication to occur.
The Modbus Communication Specification is either Binary RTU or ASCII.
