91369 Service Manual 2-17
Setup
To prevent duplication of currently used monitor names and IDs, items in these lists are not selectable. The
error checking procedure performed when SAVE is selected also specifically checks for duplications.
Note:
• Items in the Monitor Name and Monitor ID lists only display when the monitor is connected to the
network.
• When entering a monitor name or ID, do not use a space between characters.
DECNET/IP
You can configure the monitor to operate using either Spacelabs DECNET or TCP/IP network protocols. If you
are communicating with 903xx Spacelabs Healthcare monitors, you must select DECNET.
Network
The IP multicast group number of the monitor provides a filter to logically isolate one monitor from another on
TCP/IP installations. Up to 32 network numbers are available (0 to 31) with 0 as the default.
Note:
• Monitors must use the same network number to communicate.
• This is unavailable if DECNET is selected.
TTL (Time to Live)
The allowed number of hops the IP packet can take across network devices. TTL values are 1 to 64, with 16 as
the default.
Note:
TTL is unavailable if DECNET is selected.
Network Size
The network size allows configuration as:
64 — Monitor IDs from 1 to 64 are supported. No more than 64 total monitor devices can be on the
network. Provides complete network compatibility with legacy Spacelabs Healthcare monitors.
250 — Monitor IDs from 1 to 250 are supported.
Note:
903xx monitors must have the Expanded Network option installed or they will not communicate correctly
with devices with Monitor IDs above 64.
640 — Monitor IDs from 1 to 127 and from 512 to 1023 are supported with the following restrictions.
• All model 903xx Spacelabs Healthcare monitors must use monitor IDs 1 to 127, inclusive.
• All model 91xxx monitors must be configured with monitor IDs from 512 to 1023, inclusive.
1000 — Monitor IDs from 1 to 1023 are supported (compatible only with Spacelabs Healthcare 91xxx
series monitors).
