Modem Init
The ESU LT can initialize a modem. This menu selection is used to
perform this initialization and should be selected only when the
ESU LT is serving as the
M
ASTER
unit. Prior to modem
initialization, the modem should be physically connected to the
ESU LT and the power turned on. At this point, an industry-
standard AT command string is used to initialize the modem. The
string is also used following future power-up sequences.
Choices:
ENA
;
DISA
Data Rate
Selects the data rate for the control port. This should be consistent
with all units on a chain and with the modem and/or PC serial port.
Choices:

Alarms
Used to initialize the method by which the control port handles
alarm conditions.
Traps
Determines whether alarm conditions should automatically send
alarm messages (traps) to the controlling PC. The setting is for this
unit, or for slaves if this unit is a master.
Choices:
ENA
,
DISA
Output
Selects whether the alarm traps (if enabled) are sent directly or
whether the telephone number stored in the ESU LT should be
dialed first (industry-standard AT dial command sent to modem).
Choices:

D
IAL
Tel Num
This is the telephone number which is dialed to obtain alarm traps.
The string can be up to 20 characters in length and is terminated
with a semicolon
(;) as the last character. A colon (:) character is
used to represent a pause in the dial string.
For example, for number 9:5551212; dial 9, pause momentarily,
and then dial 5551212. This pause could be necessary to access an
outside line, such as a PBX.
When editing a specific character, the arrows are used to scroll from
0 to 9, then colon
(:) and semicolon (;) . The new telephone number
is entered into the ESU LT only upon pressing Enter after typing
