FUNCTION

• REMOTE

Blinks until RSC makes a
logical connection to
the remote station, then
it stays on.

Remote station is logically
connected as console terminal.
DDCMP protocol is enabled to
ensure data integrity. The comm
port is logically disconnected.

• REMOTE USER

Blinks until RSC makes a
iogicai connecjion jo
the remote station, then
it stays on.

Remote station can access comm
port with protocol.
Console terminal operation is
normal.

• USER PORT

Shows that keyswitch is
in USER PORT position.

RSC is transparent. Console
terminal operation is normal.
Comm port and modem operation
are normal (no protocol).

• LOCKOUT

Shows that keyswitch is
in LOCKOUT position.

No remote access through RSC
modem port. Console terminal
operation is normal.

RSC OPERATION
NOTES
• The key can be removed from the RSC keyswitch when it is set to
LOCKOUT or USER PORT.
• The CPU LOCAL/REMOTE switch must be set to LOCAL or LOCAL
DISABLE (not a remote position) for RSC operation.
• The CPU will not boot if the RSC keyswitch is set to REMOTE. The
console terminal is disabled.
• The LOCAL COPY indicator comes on only when the RSC
keyswitch is set to REMOTE because the local copy logic is not
functional in the other keyswitch positions.
• If the lockout logic fails, the LOCKOUT indicator will not come on
and RSC will de·tault to USER PORT mode.
• To bypass a faulty RSC unit, unplug console terminal cables from
A1 and A2. and patch them together. The B1/B2 cables can be
patched to connect the comm port to the modem.
• For VAX/PC38N - If, after the remote station connection is
established, the operator disables the console remote port, all
efforts made at the console keyboard to re-enable the port and
re-establish the logical connection again will be unsuccessful.
Both the telephone connection and modem operation will
appear to be normal. The remote station must break, then
re-make the connection after the console remote port has been
re-enabled.

USER GUIDE
OPERATION
1. Make sure RSC Data Rate Switches are set correctly.
2. Set RSC keyswitch to select mode of operation.
3. Check the RSC indicators • POWER- on
• FAULT - off
• KEYSWITCH position indicator - on
• LOCAL COPY - on if the RSC keyswitch is set to remote and the
LOCAL COPY switch is latched in.
4. For VAX/PC38N or VAX Cluster- You may have to connect and/or
enable a hardcopy terminal if you want to use LOCAL COPY.
5. For VAX Cluster - You will have to change the Z Box (VCS Disable)
switch setting to disconnect the target CPU from the cluster and
enable a hardcopy terminal.

TO SET DATA RATE SWITCHES
RSC must operate at the same data rate as the console terminal and
modem that are connected to it. The BAUD T and BAUD M switch
settings determine the data rates of those RSC interfaces.
