Subnet Mask
Purpose: Defines the subnet mask, an internal TCP/IP protocol stack variable that is used to
separate the subnetwork address from the local IP address. The TCP/IP protocol stack
performs a bit-wise AND on the IP address and the subnet mask. Each address segment
represents one byte, where 255 converts to FF hex.
This computation is used to find out if the DCS 300 (UDP Plus) or host (TCP/IP) and
terminal are on different subnetworks. If the terminal is on a different IP subnetwork than
the DCS 300 or host, you must set the subnet mask.
For example, if the IP address is 192.009.150.184 and the subnet mask is 255.255.255.0,
the subnetwork address is 192.009.150.0.
Syntax: NS
n.n.n.n
where each
n
address segment is a number from 0 to 255. The subnet mask field consists
of four separate numbers, each separated by a period.
Default: 255.255.255.0
Scan: To set the default subnet mask address, scan this bar code:
Default Subnet Mask
*$+NS255.255.255.0*
*$+NS255.255.255.0*
Or: To set the subnet mask:
1. Scan this bar code:
Enter Accumulate Mode / Set Subnet Mask
*+/$+NS*
*+/$+NS*
2. Scan a numeric value from 0 to 255 to set an
n
field of the subnet mask address from
these bar codes.
*0* *1*
*0* *1*
*2* *3*
*2* *3*
*4* *5*
*4* *5*
