Since the SANM cannot accept any NM commands, Positions 1–7 of Dipswitch 2
define certain Network Manager function options normally configured with the
CONFIGURE NETWORK MANAGER command.

Configuration Summary
The general procedure for configuring the adapter follows in the list below.
1. Set the dipswitch positions.
2. Issue the CONFIGURE ADAPTER command.
3. Issue the CONFIGURE NM command. (If this adapter will be an MHIU
4. Issue the CONFIGURE HIU command. (If this adapter will be an

OPERATION AND APPLICATION
When Position 1 of Dipswitch 2 is up, it selects a one-half second delay
after CTS is active. No delay is selected when the dipswitch is down.
When Position 2 of Dipswitch 2 is up, all HIUs are given permission to
issue a network disconnect (DISC). This permission is granted by the
NM function when it initializes the HIU. No HIUs will be given
permission to issue a DISC when the dipswitch is down.
Positions 3–6 of Dipswitch 2 represent the binary value for the number
of NM buffers to assign to an HIU when the HIU is initialized. The
number of NM buffers can range from 1 to 16. The actual binary value
selected will range from 0000 to 1111 binary where Position 3 is the most
significant bit and Position 6 is the least significant bit. The adapter will
then add 1 to the binary value to scale the actual range to 1–16.
When Position 7 of Dipswitch 2 is up, the NM function will use the
redundant media feature that uses both network ports, Ports 1 and 2, to
communicate with the secondary devices.
