Serial Data Port of Pin PS2 in LT Modes
This value can be read out through MON8-Channel. The MON-8 command RPFC (Read
Power Feed Current) requests the IEC-Q to return the current feed value which has been
read from pin PS2. The IEC-Q will then respond by issuing the MON-8 indication "APFC"
(Answer Power Feed Current) in the next IOM®-2 frame available. The codes of these
commands are given below.
Refer to "IOM®-2 Monitor Channel", page 761) for informations about the structure and
function of the Monitor Channel. See also "MON-8 Codes", page 228, for a summary of
all available MON-8 command.

Access to Pin DISS
Note 57: This section applies only in stand-alone mode.
NT and TE Modes
Note 58: This feature is only available in EOC Auto mode (see "EOC
Auto/Transparent Mode", page 55).
In these modes the output pin DISS (disable) is set to (1) if the EOC-command "close
complete loop" (LBBD) has been detected by the NT (see "Predefined EOC Codes",
page 231). It may be used to test a secondary power source (e.g. battery check). The
DISS-pin is set back to (0) with the EOC-command "RTN" or a reset.
1) If the microprocessor mode is being used refer to "Monitor Channel Access", page 101
