Configuration
Port Mode Parameters:
• Port Mode: The operation mode for this port. Ports 1 and 2 cannot be configured
as Passive or Buffer Mode ports, and the internal modem port is always configured
for Modem Mode. (Port 1 and 2, Default = Any-to-Any Mode; Serial Ports 3 and
above, Default = Passive Mode; Internal Modem Port, Default = Modem Mode.)
Depending on the Port Mode selected, the RSM will also display the additional prompts
listed in this section. In the Text Interface, these parameters are accessible via a
submenu, which will only be active when the appropriate port mode is selected, and
in the Web Browser Interface, fields will be "grayed out" unless the corresponding port
mode is selected.
• Any-to-Any Mode / Passive Mode: Allows the following Mode-specific parameter
to be defined:
◆ DTR Output: Determines how DTR will react when the port disconnects. DTR
can be held low, held high, or pulsed for 0.5 seconds and then held high.
(Default = Pulse.)
• Modem Mode: Allows the following mode-specific parameters to be defined:
◆ Reset String: Redefines the modem reset string. The Reset String can be sent
prior to the Initialization string. (Default = ATZ.)
◆ Initialization String: Defines a command string that can be sent to
initialize a modem to settings required by your application. (Default =
AT&C1&D2S0=1&B1&H1&R2)
◆ Hang-Up String: Although the RSM will pulse the DTR line to hang-up an
attached modem, the Hang-Up string is often useful for controlling modems that
do not use the DTR line. (Default = undefined.)
◆ Periodic Reset Value: Determines how often the Reset String will be sent to the
modem at this port.
Note: When communicating with the RSM via modem, these parameters will
not be changed until after you exit command mode and disconnect.
• Buffer Mode: Allows the following mode-specific parameters to be defined:
◆ Buffer DateTime: Enables/Disables the Time/Date stamp for buffered data.
When enabled, the RSM will add a time/date stamp whenever five seconds
elapse between data items received. (Default = On.)
◆ Buffer Connect: When enabled, the RSM will continue to Buffer captured data
while you are connected to the Buffer Mode port. (Default = Off.)
