Note: If the Remote Inhibit function is enabled, the RS232 interface is still available but no
hardware handshaking is available. (Xon/Xoff RS232 control only). Alternatively, the
USB interface can be used instead.
Note: Units are shipped default with the Remote Input state Disabled. Thus, no shorting
jumper is needed to operate the power source. Changes to the remote inhibit
configuration are retained after power down (Non-volatile).
Note: Master AFX units installed in cabinet systems shipped with the –OCS (Output
Control Switch) option are configured with the RI function permanently set to
Remote inhibit mode (mode 2). This prevents and operator from accidentally
disabling this switch. The master model number will show the –OCS prefix to
indicate this configuration.

External MODE Relay Control – “L” Versions only
The RS232 connector also contains a relay control output pin that may be used in
combination with suitable additional hardware to control a single phase mode shorting relay
between phases A, B and C in cabinet systems.
“A” version models have the remote inhibit function on the Aux I/O DB25 connector
instead.
This mode must be enabled in the SYSTEM screen. This control line (pin 8 and 5 on DB9
connector) puts out +5Vdc when the AFX is in FORM1 (single phase) and -5Vdc when the
AFX is in FORM2 (split) or FORM3 (three phase) mode.
