LINCS Configuration
707023-003
For CTC:
This is the last channel address LINCS will occupy on the channel through this channel
interface. Since each LAN adapter associated with the IP Channel Bridge feature requires a
single consecutive pair of addresses, the Upper Limit Channel Address should be an odd-
valued number (01, 03, 05, etc.).
For Non-SNA:
The Upper Limit Channel Address corresponds to the last device session channel address.
(Upper Limit Channel Address Channel Address - Lower Limit Channel Address + 1) must
be less than or equal to x'80' hex (128 decimal or 80 hex is the maximum number of non-
SNA device sessions that can be configured).
The Upper Limit Channel Address must also be less than or equal to x'FF'. If more than 32
non-SNA device sessions are configured, an Extended Non-SNA Device FAD must be enabled
for each group of 32 non-SNA device sessions above the base 32 device sessions.
Command Retry Support
Allows LINCS to request the channel to retry a command when certain error conditions
(outbound data parity errors or datastreaming errors) are detected on the channel. The option
should be enabled only if the host can support it (the host system programmer can give you
this information), and it must be enabled if Data Streaming is enabled. All block MUX channels
support command retry, but some byte MUX channels do not.
Toggle to ENABLE or DISABLE (default) this feature.
Data Transfer Mode
The host system programmer can tell you which Data Transfer mode to use. Toggle to select
one of the following:
• High Speed Transfer
• Normal Data Transfer (Interlocked Single Tag)
• Data Streaming (Channel/SNA only)
Data Streaming is for Channel/SNA and Channel/CTC only. It offers higher data transfer
rate that is independent of channel cable length, and that can operate over a channel cable
length of up to 400 feet (122m). Data Streaming requires:
• The LINCS node be connected to a channel that supports it.
• Command Retry Support must be enabled (on this panel).
Channel Burst Size
Burst size refers to the number of data bytes that are transferred on a byte multiplexer channel
in a single burst. Press the Enter key to toggle among the following options: 2, 4, 8, 16, 32
(default), 64, 256, and 512 bytes per burst.
Channel Burst size selections are not applicable when operating on a block multiplexer
channel.
