control system; the RTS line can be enabled as a digital output.

supported.  

•  Break statement is generated for as long as the signal is held high.  
•  Provides character pacing in units of milliseconds for all of the data 

specified. The range of the pacing is from 1 to 31 milliseconds. Pacing 
greater than 31 milliseconds defaults to the maximum (31 ms).  

•  Supports RS-485. However, additional drivers are required and specific 

protocol must be followed. The unit remains in receive mode until 
transmission is enabled with one character switching. Consult

and rear panels. On the front of the unit there are 10 LEDs for indicating the unit’s 
current status. All connections are made on the back of the unit. Refer to the physical 
views shown below. There are four rubber feet on the base of the unit for stability 
and to prevent slippage.
