Table 7.2: Communication Settings
Service Port
The Service Port is Port 450 on the front of the recorder. It can be used for connection with
TESLA Control Panel or a terminal program (to access the Maintenance Menu).
Baud Rate Sets the baud rate of the port. The default baud rate is 115,200
N81 baud.
Note: The baud rate must match that of the port of the compu-
ter connected to this port. For details about changing the baud
rate see “Setting Windows Serial Port Parameters” on page 4-
18.
For best results, use the maximum baud rate that your com-
munication link and equipment can sustain.
Direct/Modem Port
The Direct/Modem Port refers to either the recorder’s rear panel Port 405 or its (optional)
Internal Modem port, depending on the Port Select setting.
Port Select Direct Serial: Port 405 is enabled for a direct serial connection
with TESLA Control Panel or a terminal program (to access
the Maintenance Menu).
External Modem: Port 405 can be used to connect to an exter-
nal modem through a serial link.
Internal Modem: Enables a modem connection through the
recorder’s rear panel RJ-11 Internal Modem Port. Requires
that the recorder has the internal modem option installed. The
internal modem can be disabled through the Maintenance
Menu.
Baud Rate Sets the baud rate of port 405. The default baud rate is 38,400
baud. For a direct serial connection on Port 405, the baud rate
must match that of the port of the computer connected to this
port. For details about changing the baud rate see “Setting
Windows Serial Port Parameters” on page 4-18.
When configured for an internal or external modem, the baud
rate specifies the rate at which the recorder communicates
with the modem. The actual communication rate between
modems is less than or equal to this setting, depending on
what the modems can negotiate over the phone line.
For best results, use the maximum baud rate that your
communication link and equipment can sustain.
Modem Initialization
String
When using an internal or external modem, a modem
initialization string can be entered containing modem control
codes. The factory default for this field is “M1”. Refer to the
modem manual for details.
