Parameters
For devices connected with a serial Modbus slave protocol, this parameter is a number
from 1-247. The network administrator must ensure that all devices on the network have
unique addresses. Do not use the value 0
00
0 (zero) for Modbus communications because
this is the broadcast address and is inappropriate for a slave device.
P772 Baud Rate
Sets the communication rate with the master device.
4.8
4800 baud
9.6
9600 baud
19.2
19,200 baud
Values
38.4
38,400 baud
This specifies the rate of communication in Kbaud. Any value may be entered, but only
the values shown are supported. The baud rate should reflect the speed of the
connected hardware and protocol used.
P773 Parity
Sets the serial port parity for the RS-485 port.
0
No Parity (default)
1
Odd Parity
Values
2
Even Parity
Note: Ensure that the communications parameters are identical between the IQ
Radar 300 and all connected devices.
Data Bits and Stop Bits
There are eight data bits and one stop bit.
P799 Communications Control
This parameter determines the read/write access to parameters via remote
communications. If it has a value of 0, then the user can only read parameters. If it has a
value of 1, then the user can read and write parameters. If it has a value of 2, then the
user can read/write P799, but can only read other parameters.
0
Read only
1
Read/write
Values
2
Restricted access – read only except for P799 which is read/writ
