Note 1: Cable 1 can be replaced by a longer cable.
Note 2: Cable 2 and 3 have fixed lengths. Use cable 2 for RS-422 interface or cable 3
for RS-232 interface.
Procedure
1. Connect the MOXA unit to the Ethernet RJ45 connector marked MOXA on the
survey computer. Serial ports on the MOXA unit can individually be configured as
RS-232 or RS-422.
2. Connect one of the RS-232/422 ports on the MOXA unit to a free serial port on the
onboard APOS computer. Use one of the ports from on the 8 port serial card.
Normally ports 1 to 4 on this card are RS-232 and port 5 to 8 are RS-422.
3. Ensure that NPort software is installed on the Survey computer. Check that the
MOXA unit is detected and the serial ports are mapped. The serial port number for
the MOXA port the cable is connected to can also be checked and type adjusted if
needed. If NPort is not installed the installer can be found in the install folder.
4. Two cables are supplied, one for RS-232 and the other for RS-422 connection. Use
the correct cable for the connection. If RS-422 connection is used, the cable must be
connected the correct way as the pinout on the MOXA is different from the 8 port
serial in the APOS computer.
5. The APOS Survey comes with a short Ethernet STP cable. This cable MUST be
connected between the Net A and Net B sockets on the survey computer if these are
unused. Alternatively the computer may be configured with a loopback adapter. In
the latter case, the cable between net A and B should not be used.
Software installation
If ASI is not already installed as part of the APOS installation. The onboard system must
have an additional program installed in order to enable the communication with the
APOS Survey. This program is called ASI (APOS Survey Interface) and can be installed
while the current APOS/HIPAP is running. It can be installed on any of the APOS
computers, but it is recommended to install it on the computer that is normally used as
the main APOS computer (and where the serial line to the APOS Survey is connected).
The program will not alter the current APOS/HiPAP installation. The program is
supplied on a USB memory stick.
1. Insert the memory stick. The installer should start automatically. If not, open
Windows explorer, locate the file called AsiBootstrapper.exe on the memory stick
and run it.
2. When the program is installed, it will add a Start ASI entry to the menu. It will also
be added to the list of programs that starts automatically when the system is turned
on.
