Vt100 Mode; Setup And Configuration; Running Without A Terminal - Teknor Industrial Computers VIPer 821 Technical Reference Manual

6. VT100 MODE

The VT100 mode may be required to communicate with the board using a remote terminal
through a serial communication link.
In this configuration, the remote terminal must emulate VT100 or ANSI terminal and support
an emulation program such as Telix or Procomm.
The serial cable must conform to one of the following:
C O M
c onn ec to r
T X D
R X D
D T R
D S R
RT S
CT S
DC D
G N D

SETUP AND CONFIGURATION

Follow these steps for setting up VT100 Mode:


Power off your VIPer 821 and install jumper W13 (3-4) to enable the VT100 Mode.
Note: both Serial Port 1 and Serial Port 2 support the VT100 Mode.


Connect the serial cable. Note: if a full setup cable is not required a partial cable by only
the TXD and RXD lines can be used. Simply loop back the control lines according to the
partial setup cable diagram.


Power on your VIPer 821 and run the BIOS Setup program, Integrated Peripherals
option, and select a communication baud rate.


The remote terminal must be set to support the following protocol:
8 Bits / No Parity / 1 stop bit / Echo Off.
6.2

RUNNING WITHOUT A TERMINAL

The board can boot up without a screen or terminal attached. However, if VT100 Mode is
desired, but the terminal is to be disconnected, you must ensure the control lines are in an
active state. Failing this, the system may "hang" while waiting for the control lines to become
active. Wiring the cable according to the partial setup allows the lines to remain active. This
does not apply if the VT100 jumper is not set.
