seeking to communicate with the printer. In this case, a reset (RST packet) will be sent to the open connection,
and any previously stored data will be flushed. The default setting is 30 seconds.
This command permanently stores the Retransmit Timeout value in flash. The value (#) can range from 1-65535
seconds. This command sets the total timeout period for a network port connection to remain open if there is a
problem communicating between ports. Normally, after 2s, the Boca printer will retransmit data that has failed
to be acknowledged by the Host TCP. Then it will wait 4s, then 8s, etc. After a total of 300s, the Boca will send
a RST packet and terminate the connection. Any previously stored data will be flushed. The default setting is
300 seconds.
NEW FGL NETWORKING COMMANDS: Available in versions FGL44B5 and above.
Previous firmware versions did not allow you to assign a subnet mask or default gateway. The printer would
always send packets directly to the destination host. This would work on all directly connected networks. This
is referred to as a ‘direct route’. Sometimes it is necessary to run the printer on an indirectly connected network.
It must send its responses through a gateway in order to reach the destination host. Therefore, we have added
the Subnet Mask and Default Gateway commands to the printer. They can also be set through the control panel
and Web Menus.
DEFAULT GATEWAY MEDIA ACCESS CONTROL NUMBER COMMAND - <DGM>
This command returns the MAC number (Ethernet address) for the Default Gateway in the form
##.##.##.##.##.##. The MAC is used by hardware devices on the network to communicate with each other.
The Gateway MAC is obtained during initialization (see Note under Permanent Subnet Mask command).
DEFAULT GATEWAY IP ADDRESS COMMAND - <DGW>
This command returns the IP address of the Default Gateway in the form ###.###.###.###. The Gateway IP
number is used by applications on ‘indirect’ networks to communicate with each other. The default address is
10.0.0.192. This address can be changed by the user (see below).
PERMANENT DEFAULT GATEWAY IP ADDRESS COMMAND - <dgw10.0.1.254>
Note: This function should only be used by an experienced user.
This command permanently changes the IP address of the default gateway and stores it in flash. The example
above would change the address to 10.0.1.254. The Gateway Address can also be changed using the ‘Factory
or Web Menu’. The default address is 10.0.0.192. Note: the subnet value must be non-zero in order for the
Gateway Address to be valid (see below).
SUBNET MASK COMMAND - <SUB>
This command returns the Subnet Mask for the network in the form ###.###.###.###. The Subnet Mask is used
by the printer to determine if the destination is on a connected network (direct route). If not, it is sent to the
Gateway Address. The default mask is 0 (0.0.0.0). This value can be changed by the user. Do not change the
Subnet Mask from zero unless you are using a Gateway. See next command.
PERMANENT SUBNET MASK COMMAND - <sub#>
Note: This function should only be used by an experienced user.
This command permanently changes the Subnet Mask for the network and stores it in flash. The Subnet Mask
can also be changed using the ‘Factory or Web Menu’. The default mask is 0 (0.0.0.0). This is a reserved value
and is used by the printer to indicate there is no subnet. Thus the printer will treat all packets as if they are on a
‘direct route’. If you want packets sent to the Gateway Address you must assign one of the following non-zero
values (1-32):
0 0.0.0.0 (reserved) 17 255.255.128.0 (class C)
