ECHO MODE
The V93A can be placed into echo mode by sending seven semicolons (;) in
succession. While in echo mode, the V93A will echo all characters received by the
connected device back to that device. Echo mode is terminated by placing an I/O
module into command mode ($BTm<cr> where m is the desired module number.
Echo Mode would be used only when the ASCII string method of port selection is
used. If the Menu Mode(Attention character method) of port selection is used the
Echo Mode is not required.
RING DETECT RESET
The V93A has a Ring Detect Reset feature that will automatically cycle power on the
M Series unit if an incoming call is detected and not answered within seventy
seconds. The Ring Detect Reset feature is enabled by connecting a straight 2-wire or
4-wire cable between the auxiliary 4-pin modular connector on the V93A and the
DIAL service modem port on the M Series chassis.
