Cable Connections
The terminal may be configured to communicate using either a serial RS232 connection or an Ethernet telnet connection.
Although it is possible to connect both RS232 and Ethernet cables, it is only possible to use one type of connection at any time
(determined by the configuration defined in terminal set up). The Ethernet network connection may be used to connect to any
10Mb compatible Ethernet host adapter. However the Ethernet connection is most suited for use with RSC (Remote System
Control) Ethernet ports since these provide the same functionality as serial (ttya) console ports.
If connecting a serial RS232 cable to the server, it is advisable to power down the server first.
The rear of the terminal tray has the following connections.
IEC POWER
VGA
MONITOR SERIAL 2 PARALLEL SERIAL 1 10BASE T
CONNECTOR
VEXT-1,5-MM
• VGA and MONITOR
These two 15HD female video ports must be joined together using the VEXT-1,5-MM cable supplied. Connect this cable
between these ports.
• Serial 2 and Parallel
The terminal supports a local printer that can be connected to a serial (male 9-pin D connector) or parallel (female 25-pin D
connector) interface. Printer cables are not included with the terminal, and specific printers have not been qualified for this
connection.
• Serial 1
This is a male 9-pin D connector port that should be used for a serial RS232 console connection. The included 9DB female to
25DB male null modem cable can be used to connect this port to a female 25-pin D connector console port. A 25-pin to 9-pin
adapter will be needed (not included) in conjunction with this cable when connecting to a male 9-pin D connector console port.
If connecting to a SUN server, when the terminal loses power or is powered OFF, a 'break' may be generated on the RS232
(SERIAL 1) CPU port (as is common with most general purpose terminals). To prevent this halting a connected Sun server,
ensure that the "alternate break" sequence is configured. See SunSolve Info Doc 21258 for details.
If connecting the terminal using the RS232 connection to a Console Server, use cabling recommended by the Console Server
manufacturer. In this case an alternate break sequence may not be required, since some console servers are "Break Safe". Refer
to the Console Server documentation for details.
• 10Base T
This is an RJ45 port that may be used for an Ethernet server connection. This connection may be used with any 10Mb compatible
Ethernet host adapter. However the Ethernet connection is most suited for use with the RSC (Remote System Control) Ethernet
ports since these provide the same functionality as serial (ttya) console ports.
Connect an RJ45-to-RJ45 UTP cable (not supplied) between this port and an Ethernet 10Mb compatible hub or switch. The
network hub/switch should in turn be connected to the server RSC Ethernet port(s). The terminal supports 12 concurrent telnet
connections when configured in Econ-80 screen column mode. The number of concurrent telnet connections reduces to 8 when
using standard 80 column mode.
Note: It is advisable that this network remains a private network for security reasons. If only one server is to be
connected to by the terminal, a crossover (or cascade) UTP cable may be used.
When using an Ethernet console connection, the alternate break sequence need not be defined. However, the RSC Ethernet port
must be configured using the "rsc-config" command.
Finally, connect the powercord to the IEC connector.
