 SECTION 6  ACCESSORIES 
RS232 Adapter:  
This cable/adapter will convert the SPC output of the 
ProScale Display to an RS232 signal for input to a 
PC. 
1 INPUT; 1 RS232 OUTPUT 
ProMUX 3 
A hardware interface device providing 
communication and control of one to three ProScale 
Displays or Readheads from a PC or PLC. 
1, 2 or 3 INPUTS; 1 RS232 OUTPUT 
ProMUX-8 
A  multiplexer  designed  for  OEM  and  system 
integrators for use in acquiring positional information 
(non-CNC).  It communicates with a PC or PLC  via 
RS232 or RS-422.  
Up to 128 INPUTS (15 ProMUX-8 can be connected 
to the same RS-422 bus), 1 RS-422 OUTPUT. 
Pro-RF™  
A 2 way system consisting of a base module and a 
remote module that communicate over a bi-
directional RF interface. 
Pro-RF can support up to 32 remote modules up to 
300 feet from the base. (RS-232 Output) 
ProScaleRF Receiver 
A 1 way system consisting of a base module and a 
ProScale RF Display. 
ProScale-RF can support up to 63 remote  Displays 
up to 100 feet from the receiver. (RS-232 Output) 
Analog Interface Unit (AIU)  
The AIU  is designed  to  provide  an analog signal 
output  that  is  proportional to the  current  position 
being  displayed on a ProScale linear measurement 
system.  
The AIU provides a DC signal range from 0 to 5 volts 
or 0 to 10 volts.
