REMOTE TERMINAL COMMUNICATION
The primary cartridges for the Scanner also can display test information on some
other remote terminals. This communication feature is designed to work with
equipment that operates in a VT100 format, which is a common industry standard
for terminal operation. The VT100 terminal adapter cable (MT2500-500) can
connect to a VT100 terminal or a serial port on an IBM compatible personal
computer (PC). If the scanner is used with a PC,
VT100 emulation
software must
be installed in the PC.
All remote terminal displays will be in the same format as the 4-line scanner display
screen except the CODES and LIVE DATA display. If more than four lines are
required to display any service codes found in the vehicle, the complete code list
will appear on the screen at one time.
All scanner operations can be controlled from the remote terminal keyboard or
from the scanner. Using the scanner with a remote terminal requires an optional
terminal communication cable, which connects to the RS232 communication port
on the top right of the scanner.
The VT100 terminal adaptor cable (MT2500-500) for the scanner has a 25-pin
(DB25) female connector. The scanner transmits data on pin 3 and receives data
on pin 2 at the DB25 connector. If the remote terminal connector matches this
arrangement, the MT2500-500 terminal adapter cable can be used. If it does not,
another adaptor (usually called a
“
null modem
”
adaptor) or a special cable may be
required. Refer to installation manuals for specific equipment for connector and
cable information.
Follow these steps to connect the scanner to the terminal and use the
communication program:
1: Use the COMMUNICATION SETUP program on the CUSTOM SETUP menu
to set the scanner at a baud rate that is compatible with the terminal. See the
“
Custom Setup
”
section for more information.
2: Refer to the terminal manufacturer
’
s instructions for information on baud rates
and any required switch settings or start-up conditions for the terminal. (The
communication parameters for a PC should be set to 4800 Baud, No Parity, 8
Data bits,1 Stop Bit.)
3: Connect the terminal communication cable to the scanner and to the terminal.
The scanner can be connected to vehicle power and at any desired menu or
test mode when the cable is connected.
4: Press either the
Y
or
N
or up-arrow or down-arrow key (s or t, or equivalent)
on the terminal to start the scanner communication with the terminal.
