3.6.6 Remove/Replace an expansion card
It may be necessary to remove an existing expansion card if probe connectors are
obstructed.
Important Note: The compact connectors are a very tight fit and the connections can
easily break off. Do not apply excessive force when fitting and removing the compact
connectors.
To remove/replace an expansion card:
1. Delete the card in the sc1000 controller. Refer to section 6.3.6 on page 115 .
2. Remove power from the instrument. Remove the probe module cover.
3. Disconnect all cable connections to the card.
4. Remove the screws securing the card and remove the card.
5. Replace the card and configure the card.
3.7 Install an sc1000 network (sc1000 bus connection)
An sc1000 network connects up to 32 participants ( Figure 27 ). Participants are defined as
anything attached to the network including probes and optional cards but not counting the
display module or probe modules. Only one display module is allowed for one sc1000
network.
Each probe module has an sc1000 network interface ( Figure 28 ). Use the sc1000
network cable and the sc1000 network connector to set up a network. Suitable cable and
network connector is available from the manufacturer.
