The RS485 interface termination can be done by short circuiting pin no. 19 and 20 at the desk and panel type
enclosures or by jumper JP4 on the interface board within the stainless steel housing . These short circuits
terminate the line with an internal termination resistor of 100 Ω.
The 20mA CL ASCII output is disabled by default. The connections should be made as given in figure 9.1 for
enabling this output. (Enabled output is not available for 12 V DC instruments ).
