5.18.5 RS232 Serial Interface

5.18.5.1 RS232 Interface and Remote Inhibit Function
On AFX Series models with firmware revision numbers lower than 2.0.13, there is a conflict
between the RS232 interface and the Remote Inhibit function. Both cannot be used at the
same time. To enable the Remote Inhibit input control line, the RS232 interface must be
disabled. This can be done using the browser interface over LAN or USB or from the front
panel. If the Remote Inhibit function is needed, use the USB interface instead of RS232.
To disable RS232 from Web browser, select
SYSTEM Menu -> INTERFACE SETUP and move
the SERIAL CONFIGURATION ENABLE position
to OFF.
To disable RS232 form the front panel, press
the CONFIGURATION key to the left of the LCD, select Interfaces, then select RS232
Interface and set the Status field to Disabled. Refer to section 6.8.5.4 on page 173.
Note: For units with firmware revision 2.0.13 or higher, the RS232 interface is
automatically disabled when enabling Remote Inhibit.
5.18.5.2 "A" and AG" Versions
The RS232 serial interface on "A" or "AG" versions of the AFX Series is incorporated in the
DB25 Auxiliary I/O connector located on the rear panel. Refer to section 4.14, "Auxiliary
I/O" on page 44 for details.
