5.25 Remote RTU1 MAC Address
This is the RTU1 MAC hexadecimal address of the second RTU connected to a remote 2788. It is
stored at the remote 2788 and is used when the remote radio is in forwarding mode 0 or 2.
rtu1=##-##-##-##-##-##<CR>
Example: 01-23-de-ad-be-ef<CR>
5.26 Master RTU MAC Address Table
This is the command format for entering RTU hexadecimal addresses in the master radio RTU
table. It is used when the master is in forwarding mode 0 or 2. Up to 512 RTU MAC addresses
may be saved in the master RTU MAC address table. Both RTU number (000 to 1ff) and
associated MAC address are in hexadecimal. The table is initially cleared to all zeros. Normally
the table is filled, starting at 000 and progressing to a maximum number of 1ff. The entire table
is scanned for each forwarding operation by the master radio when fm=0 or fm=2.
rtu[###]=##-##-##-##-##-##<CR>
Example: rtu[000]=01-23-45-ab-cd-ef<CR> ; rtu[1ff]=01-23-de-ad-be-ef<CR>
5.27 Host MAC Address Table
This is the command format for entering host hexadecimal addresses in the 2788 host table. It
is used when either the master or remote radio is in forwarding mode 0 or 1. Up to 16 host
MAC addresses may be saved in the host address table. Both host number (0 to f) and
associated MAC address are in hexadecimal. The table is initially cleared to all zeros. Normally
the table is filled, starting at 0 and progressing to a maximum number of f. The entire table is
scanned for each forwarding operation by the master or remote radio when fm=0 or fm=1.
host[#]=##-##-##-##-##-##<CR>
Example: host[0]=01-23-45-ab-cd-ef<CR> ; host[f]=01-23-de-ad-be-ef<CR>
5.28 High QOS (Quality Of Service) IP Address Table
This is the command format for entering high QOS IP addresses in the 2788 QIP table. Most
commonly the IP address of polling host computers is entered into both the master radio QIP
table and all remote QIP tables. This gives priority for high QOS device sources at the master
radio and high QOS destinations at the remote radios.
Up to 16 IP addresses may be saved in the QIP table. Host number (0 to f) is in hex and
associated IP addresses are in standard dot notation. The table is initially cleared to all zeros.
Normally the table is filled, starting at 0 and progressing to a maximum number of f.
Note that RS-232 always has high priority since it is most commonly used for polled systems.
host[#]=###.###.###.###<CR>
Example: host[0]=192.168.1.2<CR> ; host[1]=192.168.1.3<CR> ; host[f]=10.0.0.10<CR>
