INSTALLATION
Set ALB to OFF.
Return S6 to the setting required by the application in use.
Digital Loopback (DLB)
Connect a remote modem to the analog side. Set DLB, on the
front panel, to ON. After a delay of 5 seconds, the remote
modem's front panel RTS, DTR, CD, and CTS LEDs will come
on. Type any character on the remote terminal. The remote
modem's TD and RD LEDs will blink and the remote terminal
will receive its character back.
For the two modems to communicate with each other, one must
be set to ORG mode and the other to ANS. These switches are on
the front panel of each unit. Make sure that the 2W/4W switch
(S7) is set per the application.
