Baud = baud rate from 110 to 19,200
Parity = odd, even, or no parity
Format = number of data bits (7 or 8) and stop bits (1 or 2)
Flow = XON/XOFF or other flow control protocol (version dependent)
Interchar (Delay)
= intercharacter delay, to allow interfacing with slow peripheral devices.
Modem = provides some special modem options for cellular telephone links (version specific).
The
Default selection sets the default values of the configuration parameters. These are:
Baud = 4800
Parity = none
Data bits = 8
Stop bits = 1
Xon/Xoff = enabled
Intercharacter delay = 0
In versions which support remote control of the receiver by a host computer, Terminal puts
the receiver in its remote mode. Once terminal mode is activated the receiver keypad is locked
out; commands will be accepted from the serial port only. Local control can be restored from the
host or by a "hard" reset (simultaneous activation of
SHIFT and ESC). See the WILDLIFE HOST
User's Manual that accompanies HOST software for further information on terminal control.
Auto-answer is a modem control function which allows a remote host to establish terminal
control by telephone. This feature is available for system service from Lotek, as well as for user
applications involving telephone, local radio
or satellite links between the receiver and a central
processing station.
If the receiver is connected to a “Hayes compatible” modem (that is, a modem which supports
the basic “AT” command set), selecting auto-answer mode initializes the modem to its power-up
defaults and sends the current SRX_400 communication settings. The modem will enable its
auto-answer feature (on some modems an LED “AA” indicator will light up) which means it will
answer all incoming calls and negotiate a data link with the calling modem. The SRX_400 also
asserts its own auto-answer state, which will cause it to enter terminal mode when a call is
received, echoing all display information to the serial port and responding to commands from a
remote terminal. Auto-answer defaults to OFF on power up, so if the receiver is turned off
between sessions auto-answer must be invoked again, even if the modem’s auto-answer feature
is still enabled. Also, because the auto-answer command sends SRX_400 communication settings
to the modem, it must be re-enabled if these settings are changed.
Use of the Auto-answer feature in remote terminal communications is further described in the
WILDLIFE HOST User's Manual for Lotek’s HOST software, and in Example 3, at the end of
this document.
The
CODE key is used in some software versions to enter a five-digit "pass code"
which authorizes access to functions which can reformat, reallocate or overwrite
memory. There are currently three such functions: New Prom initialization (
SHIFT +
F1
), Memory Test in the Event_Log or Code_Log menu, and the memory initialization sequence
provided on entry to a number of data logging programs. Once it is entered, a new pass code
may be "locked", which means that it will also be required to authorize further changes. Use this
