Setup LCP File Server
Screen 3: Setup LCP File Server Port
Port is the communications port designation and interrupt
request used by the LCP File Server to communicate
with the host computer. Press ENTER to open a list box
window with the options:
COM1
COM2
COM3
COM4
Use Base Address of UART
Select the desired option and press ENTER. This
advances the display to a list box window with options for
interrupt request ( IRQ). Select a value for IRQ from the
list between “ 2” and “15” and press ENTER.
Bits/second (Baud) is the baud rate used by the LCP
File Server to communicate with the host computer. Press
ENTER to open a list box window with the options:
2400
4800
9600
19200
57600
115200
Select the desired baud rate and press ENTER.
Tx Enable Bit is the transfer enable bit used with the LCP
File Server is used in an RS-485 network.
The LCP File Server allows a network of computers to
be accessed by one office computer. To do this requires
the use of an RS-485 communications device. Because
an RS-485 device cannot transmit and receive data
simultaneously, there is a mechanism used by the device
that indicates whether it should be prepared to receive
data, or to transmit data. This mechanism is called the
Transmit Enable Bit.
Press
ENTER to open a list box window with the following
options:
!DTR
!RTS
!RTS!DTR
DTR
None
RTS
RTSDTR
If using an RS-232 link to the office computer, this field
should be set to “ None” Otherwise, set this field to the
value used by the RS-485 device that is connected to the
DMS i1000 computer. The literature that came with the
RS-485 device should provide this information.
Maximum Retries is the number of retries that will
automatically occur in the event that the host computer
does not respond to a request message. The default value
for this field is 1, but it can increased if it is determined
that the communications cable is in an electrically noisy
environment. Press ENTER to open a field edit window
and enter a value between 0 and 255.
Timeout is the amount of time, in milliseconds, that the
LCP File Server will wait for a response from the office
computer before it decides that no response is coming. At
this time, it determines the office computer to be off-line.
The default value for this field is 100 ms. Press ENTER
to open a field edit window and enter a value between
100 and 9999.
NOTE: All of these fields are associated with communication
through a wireless transmitter. These fields can be ignored
when using a wired connection.
