3. NXG_DGS: General Operation
3.1
Find and Connect to NXG
Before the user can begin performing diagnostic functions or send and receive messages,
NXG_DGS must locate NXG on the local network. NXG is a server, awaiting
connection requests from the application or POS devices, which are clients.
When the IP Address of NXG is Unknown
NXG_DGS begins by attempting to discover NXG by sending a UDP Broadcast message
to the local broadcast address of 255.255.255.255. Sending to this address keeps the
broadcast within the LAN, since routers will not forward messages sent to this address
beyond the local subnet.
NXG will respond to the broadcast messages, sending NXG_DGS the IP and MAC
addresses. This will allow NXG_DGS to connect to NXG via TCP/IP.
To connect with NXG, press the FIND NeXGen function button on the NXG_DGS
window. See figure 3.1–1 below for details.

Once the IP and MAC addresses are obtained, the application still needs to connect with
NXG. This is done by pressing the Connect function button on the console display.
Pressing the CONNECT button causes NXG_DGS to sync with NXG. Three TCP
packets are sent containing a TCP header and no data:
1.
2.
3.
Client->server: SYN
Server->client: SYN/ACK
Client->server: ACK
When the IP Address of NXG is known (Refer to Figure 3.1-2 below)
The user can select an option to have NXG_DGS connect with NXG without having to
broadcast. The EDIT IP ADDR function button provides this function.

Emulating POS Functions
The NXG_DGS application will be used to send messages to NXG to configure the
controller or obtain additional diagnostic details.
In order to decipher messages returned by NXG to the application, the user has to have an
understanding of the ANDI message interface which is beyond the scope of this manual.
Please refer to Appendix C for a description of a few basic ANDI message strings
returned by NXG and their use for diagnostic purposes.

5. File Transfer Protocol- FTP
File Transfer Protocol (FTP) is supported by the NXG controller. FTP can be used to allow the
user to manually cold start the system or clear contents of certain directories within the system
disk (Compact Flash- CF).
If the user enters a folder name (e.g. CK) as the user name, the user will have read/write access to
that folder. As new folders are added in the future, this function will support access to those
folders without requiring a change of the NXG application.
NOTE: Please contact Allied electronics, Inc. before accessing the NXG system or
deleting the contents of any system directories. In most cases, this function will only be
used to update graphic files on the NXG’s CF or perform other updates to the system.
FTP via browser- username and
password window

Appendix A- Port Status Messages
a. XX: Not In Use
This port is not presently in use.
b. XX: CTS/DSR Dn
Both CTS and DSR signals are down. Possible causes are:
ƒ The External device is not running
ƒ Cable problem (disconnected, pin-out error, broken wire, etc)
ƒ Port problem (NXG hardware error)
c. XX: CTS/DSR Up
Both CTS and DSR signals have been restored. This message will be replaced by a Link Up status
once data is transmitted between NXG and the external device.
d. XX: DSR Down
The DSR signal is down. Possible causes are:
ƒ The External device is not running
ƒ Cable problem (disconnected, pin-out error, broken wire, etc)
ƒ Port problem (NXG hardware error)
e. XX: DSR Up
The DSR signal has been restored. This message will be replaced by a Link Up status once data is
transmitted between NXG and the external device.
f. XX: CTS Down
The CTS signal is down. Possible causes are:
ƒ The External device is not running
ƒ Cable problem (disconnected, pin-out error, broken wire, etc)
ƒ Port problem (NXG hardware error)
g. XX: CTS Up
The CTS signal has been restored. This message will be replaced by a Link Up status once data is
transmitted between NXG and the external device.
h. XX: Loop Error
For current loop based interface ports, the NXG expects to receive an echo of each character that
is transmitted. When this fails, a “loop error” indicates echo failure. Possible causes are:
ƒ Cable problem (disconnected, pin-out error, broken wire, etc)
ƒ Distribution Box problem
ƒ Device problem (e.g. a dispenser is down)
ƒ Port problem (NXG hardware error)
i. XX: Rx Timeout
The NXG port has marked a receive time out. This message is displayed when the external device
doesn't return the proper response to the NXG. Possible causes are:
ƒ External device ignores NXG (busy or locked up)
ƒ Cable problem (pin-out error on Receive Data and/or Transmit Data)
ƒ Port problem (NXG hardware error)

Allied Electronics, Inc.
NeXGen Diagnostics Program Manual
j. XX: Rx Parity
The NXG port has marked a receive parity error. A parity error occurred while receiving a message
from the external device. The message is discarded; usually this error will be corrected. Persistent
marking of this message or cases where the port will change from Link Up to Rx Parity can be due to
device ID conflicts on the channel in question. Examples are:
ƒ Two dispensers are ID’d the same on the dispenser port
ƒ Two card readers are ID’d the same on the CAT, CRIND or DPT port
The message can also be noted if there is a hardware problem with a device on a multiple device
channel (e.g. dispenser).
k. XX: Rx Framing
The NXG port has marked a receive framing Error. A framing error occurred while receiving a
message from the external device. The message is discarded, usually this error will be corrected.
Persistent marking of this message or cases where the port will change from Link Up to Rx Framing
can be due to device ID conflicts on the port in question. Examples are:
ƒ Two dispensers are ID’d the same on the dispenser port
ƒ Two card readers are ID’d the same on the CAT, CRIND or DPT port
The message can also be noted if there is a hardware problem with multiple devices on a port (e.g.
dispenser).
l. XX: Await Cnfg
The NXG is waiting to be configured before this port becomes active. Example: The dispenser ports
are not active until the POS has sent dispenser configuration.
m. XX: Await Strt
The NXG is waiting for the external device to respond to a start-up request. Example: As part of the
configuration process the POS sends credit network parameters to the NXG. After receiving these
parameters, the NXG will issue a Network Start-Up request/ card table download request to the
Credit Card Host. The NXG will not send any other messages to this port until the Credit Card Host
has processed the Start-Up message.
The GSM port in Gilbarco systems will also display this startup message if the host configuration has
not been processed.
n. XX: Link Up
This is the normal state for any given port. The port is up and running and no errors have been
detected.
o. XX: Disabled
The interface provided via this port has been disabled. The NXG program doesn't support this
device. Call technical support to order a program with this feature enabled.
p. XX: Port Error
The NXG was unable to access the device. This can occur when there is a problem found with a
port on the main board. Replace the NXG controller.

q. XX: Log Off
The external device has logged off. It has informed the NXG that it was (temporarily) going offline.
This is typical of a POS system shut down.
r. XX: Device Ver
The external device is running an incompatible software version. To correct this problem, upgrade
the device to the appropriate software version and/or revision and restart the device.

The Dispenser Status command is used to obtain the status of one or more dispensers.
When Dispenser is set to ALL (00) the response message length depends on the number of
configured dispensers. When Dispenser is non-zero only the status of the selected dispenser
combination is returned.
Each time the status of a dispenser changes, an unsolicited Dispenser Status response
message is sent to all DIS service subscribers (the completion code field will be set to "N").
This indicates that the receiving device shouldn't send a response message.
