Sample Response to the “add_master” Command
Each row of the master list contains an index number enclosed in brackets, the IP ID
of the device to which the system communicates (provided in decimal and hex), and
an IP address separated by a colon (:). Each line appears as follows.
[INDEX #]decimal IP ID(hex IP ID):IP ADDRESS
To add an IP address to the master list, enter the index number, the IP ID (in
decimal), and the desired IP address separated by decimal points (.), after the
“add_master” command. For example to add IP address 132.149.2.122 as the first
static master on IP ID 03, enter the following.
add_master 00.3.132.149.2.122
To delete an IP address from the master list, enter the index number, a zero, and IP
address of 0.0.0.0 separated by decimal points (.), after the “add_master” command.
For example, to delete the IP address that was just added, enter the following.
add_master 00.0.0.0.0.0
ip_adr
Enter the “ip_adr” command and depress
ENTER
to display the IP address of the
connected CEN-COM. To change the IP address, enter the new IP address after the
“ip_adr” command. For example to change the IP address of the connected CEN-
COM to 132.149.2.122, enter the following.
ip_adr 132.149.2.122
ip_mask
The IP mask (Internet Protocol Mask) is a number that is used in conjunction with
the IP address to determine whether or not a particular IP address is on the local
network (or ‘subnet’). If it is on the local network, it communicates directly with that
device. Otherwise, it uses a router attached to the network. The IP mask for any
device should be assigned by whoever manages the local network. The format of the
IP mask is four numbers separated by dots (e.g., 255.255.255.0).
To change the IP mask, enter the new IP mask after the “ip_mask” command. For
example to change the IP mask of the connected CEN-COM to 255.255.255.0, enter
the following.
ip_mask 255.255.255.0
