MODEM COMMUNICATION TO ABB RELAYS
Figure 40. ATDT Sample String and Successful Connection Banner
If the modem does not connect, then the REL512 may have been sending its time string during the dial
up procedure. If this is the case, redial or modify the reconnect tries in the S19 register.
If the modem does connect, then depress the "/" key or Backspace key on the keyboard to reveal the
REL512 startup screen illustrated in Figure 41.
To exit the session, depress the hang up icon located on the HYPERTERMINAL screen or the HANG UP
submenu located on the TERMINAL screen. Also one may send the AT&H0 string for hang up.
