Table 18 lists all configuration items, what each item is used for, and the allowable
value options for each item. The factory-set default values are underlined.
Table 18. ESCON Channel Attachment Items
Configuration Item Description Value Options
ESCON Link A
Installed
Specifies if ESCON Channel Link A is installed. Yes or No
ESCON Link B
Installed
Specifies if ESCON Channel Link B is installed. Yes or No
Device Address Specifies the 2-digit hexadecimal channel address which
includes the device address.
Notes:
1. In simplex mode, only one device address is required.
2. In dual simplex mode, each printer requires a unique
device address. Printer 1 requires an even number
(for example, X'30'); Printer 2 requires the next
consecutive number (for example, X'31').
3. The duplex system does not require a unique number.
It can use either of the addresses used for dual
simplex Printer 1 or dual simplex Printer 2. However,
it is often easier from an operational viewpoint to
assign duplex a separate address (so the duplex and
simplex printers look like unique devices to the
operating system). The general convention in this case
is to assign the duplex system the next consecutive
address (even) after the address for simplex Printer 2.
For example, if you define Printer 1 in dual simplex
as X'30', you should then define Printer 2 in dual
simplex as X'31', and, optionally, define the complete
system in duplex as X'32'.
4. The device addresses specified above must match the
device addresses defined to the host PSF software,
and in the case of S/390 hosts, the I/O device
definitions.
00 to FF (Hexadecimal notation).
Default is X'00'
Multi-host
environment flag
Shows whether a multiple host printer-sharing system
exists. If this environment flag is set, all hosts are
required to use the assign/unassign protocols of the
attachment architecture. (Not supported on all printers.)
