Table 8 TT-3022D X3 pin assignment
The
Î
symbol means that the signal is generated by the Trans-
ceiver.
For full operating specifications for the serial interface, you are
kindly requested to refer to the CCITT Rec. V24 and the EIA/TIA-
232-E specifications.
2.5.2.3
Interfacing to peripherals
To Interface the TT-3022D to a TT-3606C Message Terminal, sim-
ply use the communication cable enclosed in the delivery.
The TT-3022D optionally uses either hardware or software flow
control.
Hardware flow control is accomplished by using the DTR and CTS
signals.
2 The RI indicator goes high (approximately 8 Volts), when a message or
an EGC is received. RI is reset to low when the message/EGC has been
printed and/or routed to external printer/DTE equipment.
