APX D-3
COPright
The execution of this command causes the copyright
information to be printed.
DISACK (on/off)
This command when enabled instructs the modem to
disable the acknowledgment request on the information
packet. This is used when the designation device will
respond with its own acknowledgment.
Factory default = OFF.
DISCONnect (1-254)
The disconnect command. The execution of this command
immediately initiates a disconnect request with the
currently connected node or in a multi-connect
environment only a specific node may be addressed.
DTR_enab (on/off)
The DTR enable command. This command, when enabled,
allows the ESTeem modem to monitor pin 20 of the
RS-232C connector in regards to the status of an external
device connected to it.
ON: Enables monitoring the DTR signal on pin 20 of
the RS-232C connector. If DTR is at a space
condition, then the modem is enabled. If DTR is
at a mark condition, then the ESTeem modem will
be disabled. The normal operation of this line is
for the ESTeem modem to have status on the
external device, out-putting to pin 20. This line
can act as a status to the ESTeem when the
external device is ready to transmit or receive
data.
OFF: Disabled
Factory default = OFF.
Note: If the DTR command is enabled and the line is
disabled then the ESTeem will perform a
"Disconnect" if connected. The DTR Command
will also activate the Data Carrier Detect (DCD)
Line (Pin 8) to toggle High when connected and
Low when disconnected.
ECHO (on/off)
This command enables the ESTeem to echo characters
received from the input device back to the input device.
ON: Enabled.
OFF: Disabled.
Factory default = ON.
EDit (on/off)
This command enables the EDIT functions from the
CONVERSE Mode.
Factory default = ON.
FActory
The factory default command. The execution of this
command causes the ESTeem to restore the command table
values from factory values that are stored permanently in
memory. This will allow the user the ability to restore the
ESTeem to factory conditions during testing or set-up.
FLASH
This command places the ESTeem in Flash mode for
reprogramming of the operation system.
FRAck (1-255)
This command programs the frame acknowledge delay in
milliseconds. This value is used as a minimum time before
decrementing the retry count and retransmitting a packet if
the retry count is not zero.
Factory default = 50.
GE_CTRL
This command enables the General Electric controller
protocol. For further information please reference the EST
Engineering Report on General Electric controller
interfacing.
ON: Enabled.
OFF: Disabled.
Factory default = OFF.
