RSM Series; Remote Site Managers - User’s Guide
8.3. The Direct Connect Feature
The Direct Connect feature allows you to initiate a Telnet, SSH or Raw Socket
session with the RSM and make an immediate connection to a speciﬁc RS232
Port of your choice, without ﬁrst being presented with the command interface.
This allows you to connect to a TCP port that is mapped directly to one of the
RSM's RS232 Serial Ports.
Direct Connect employs unique, pre-assigned TCP port numbers for each
RS232 Port. The user connects to the port of choice by including the
associated TCP port number in the Telnet or SSH connect command line.
The Direct Connect feature can be individually conﬁgured at each RS232 Port
and can be used to connect to Any-to-Any, Passive, Buffer, or Modem Mode
8.3.1. Standard Telnet Protocol, SSH and Raw Socket
The Direct Connect feature allows you to establish port connections using
either Standard Telnet Protocol, SSH encryption or Raw Socket. When
Standard Telnet Protocol is used, the RSM will respond to all IACs.
When conﬁguring a port to allow Direct Connections using SSH protocol, note
that the Direct Connect option (Port Conﬁguration Menu, Item 31), must be set
to "On - Password" as described in Section 8.3.2.
When conﬁguring a port to allow Direct Connections using either Standard
Telnet or Raw Socket Mode, note that the Direct Connect option (Port
Conﬁguration Menu, Item 31) may be set to either "On - Password" or
"On - No Password".
