Communications 
The TE Series starter is shipped from the factory ready to accept  
RS-485 Serial Communications using Modbus RTU protocol. Additional 
detailed instructions on accomplishing communications are available in 
Serial Communication Supplement to this manual. F065 – F067 are 
used to set the communications parameters in the starter for use by the 
adaptor module. F068 determines how the Start / Stop functions work 
through the comm. port. 
F065 =  Communications 
Factory Setting = 0 (Disabled) 
Range = 0 – 2
 
This enables serial communications with remote monitoring and 
control systems and sets the format for Modbus RTU protocol. 
Once Enabled, the local start / stop inputs are altered to avoid 
inadvertent starting. See F068 for details.  
When F065 = 0, communications are disabled. 
When F065 = 1, uses the std 11 bit Modbus format w/ parity bit. 
When F065 = 2, a non-standard 10-bit format without a parity 
bit is used to accommodate some systems using this method. 
F066 =  Baud Rate 
Factory Setting = 9.6 KB 
Range = 4.8 to 19.2 KB
 
Set value to either 4.8 KB, 9.6 KB or 19.2 KB and match the 
setting of the host device. 
F067 =  Modbus Address 
Factory Setting = 1 
Range = 1 – 247
 
The Modbus communications protocol allows each node to 
have up to 247 connected devices but each must have a unique 
address. Two devices with the same address will result in a 
communications error. 
F068 =  Remote Starter Control 
Factory Setting = 0 (disabled) 
Range = 0 – 3
 
Use this to program how the TE Series starter is to be 
controlled when using serial communications.  
When F068 = 0, the starter can be monitored by the Comm 
port, but not controlled. 
When F068 = 1, the starter will be controlled by the comm port. 
In addition, the Start / Stop inputs are altered as follows: The 
hard-wired Start command is put in “AND” logic with the Comm 
port; both Start commands must be on for the TE to start. The 
Stop function is put in “OR” logic; either the Comm. port Stop 
command OR the hard-wired Stop will cause the TE to stop.  
When F068 = 2, the TE starter is in full control of the Comm. 
port only. Local Start / Stop inputs become completely inactive. 
Use this function only when controlled shutdown is a priority. 
When F068 = 3, the TE starter will change the function of the 
Jog / Remote Input to cause a switch between the functions of 
setting 0 and setting 1 as listed above. When the input is open, 
the starter will respond to the Comm port as per setting 0 
above. When the Jog / Remote Input is closed, the starter will 
respond as per setting 1 above. Use this function if it is 
necessary to have a return to local start/stop control should the 
communications system fail or become disconnected.

Special Note when using Serial Comm:  
When F068 = 3, the function of the Jog / 
Remote Input on TB-1 terminals 7 and 8 will 
change. Closing the Input will cause the 
Comm. port control to function as per setting 
1. Leaving the input open will cause the 
Comm. port to function as per setting 0.  
 
When F068 = 1, 2 or 3, the Jog function will 
cease to operate. Since Jogging is a local 
function, set F068 to 0 when using it.
