2.5.2.3.1
TT-3606A Message Terminal
To Interface the TT-3020B to a TT-3606A Message Terminal, simply use the 30cm
communication cable enclosed in the delivery (part no TT-61 100921).
An extended serial communication cable should not exceed 100 meters as the TT-3606A
works on 4800 Baud using the RS-423 standard.
2.5.2.3.2
IBM Compatible PC (Personal Computer)
Interfacing the TT-3020B to a IBM Compatible PC, simply use the communication cable
enclosed in the delivery: Either 9-9 pin (part no TT-61 100823) or 9-25 pin (part no
TT-61 101034).
An extended communication cable should not exceed 8 meters as the TT-10202A
Message Terminal emulating software works on 4800 Baud using the RS-232C standard.
As the PC hardware normally does not conform to the RS-423 standard the maximum
length of the connection cable is less than for the TT-3606A solution.
As the TT-3020B rely on the CTS and DTR hardware handshake signals it is very
important that the PC you use is IBM hardware compatible with respect to the serial
communications interface.
2.5.2.3.3
Computerized equipment
Before connecting the TT-3020B to any computerized equipment you are recommended
to consult the computer installation manual to check the pin assignment of the serial
communication port.
Your TT-3020B is configured as Data Communications Equipment (DCE).
Most computers are configured as Data Terminal Equipment (DTE).
If this is the case for the particular computer, you will probably be able to provide the
necessary connections with a multi-wire cable, as shown in the tables below:
