The next two parameters are optional. The are used to “re-map” one node address to
another. Remapping effectively replaces the original node ID in a packet with the remap
node ID.
Port Programming
Each serial port that is to be active, sending and/or receiving pages, must be described in
the oparam.cds file. There are several distinct opcodes for programming the port
descriptions. Of these the “port mode” is the most important, as it sets the baud rate, type
of TNPP link, and other properties of the link. The port programming parameters have a
common lead-in format, which is:
The Port programming opcodes and their parameter lists follow:
pp pp Port bits for the port to do remapping for. If a port is not
selected here then a packet with this node ID received at the
port will not be remapped.
rr rr rr rr Node ID to remap to. Same format as the original Node ID.
cc 04 nn nn nn nn pp pp pp pp ii
Inertia value to use when sending a page from
Central to this node ID. May be zero for Simplex
Inbound ports.
A
ccept-from port bit mask, 16 bits as high byte, low byte. See
Table 45 for bit mapping. A packet with “node ID” will be
accepted for routing at all ports set “on” here. If port does not
have its bit here set “on” the packet will not be routed. The
reply to the sending node will be <CAN> or <ACK>, depending
on the BAD_PORT setting in the receiving port’s options field.
Route-to port bit mask, 16 bits as high byte, low byte.
See Table 45 for bit mapping. A packet with “node ID”
will be routed to all ports set “on” here.
Node ID, four bytes, MSB first. Node IDs are 32 bit numbers. Only
the low 16 bits are currently used, the high (leading) 16 bits are
reserved for future use and should be programmed as zeros.
opcode for Node Table programming
count 0A, or 10 if remapping is active for this node
aa NIU card address.
uu Port ID, same as the Unit number on Multiport cards for
IXO. This is 1 for serial port A, 2 for port B, and matches
the “CHAN n” LED values.
cc Argument count.
