Overview:
The MLIM-5-2400 module provides PCMCIA memory card support as
discussed in the MLIM-5 section and also provides 1200/2400 Baud
telephone modem communications capability. Installation of this module will
allow the full complement of serial communications/ control of the OMP-
MODL from a remotely located PC equipped with a modem. Additionally,
loggers equipped with a modem can utilize the Pager Alarm Output feature
from within HyperWare (see Appendix A).
The MLIM-5-2400 incorporates a low power modem, drawing approximately
50mA during operation (off-hook) and 0 mA while quiescent (on-hook).
Module Installation:
Installation of the MLIM-5-2400 into the OMP-MODL System Base is unique
in that it requires a special set of signals only available from the connector
on the MLCPU-1 module. For this reason, the MLIM-5-2400 can only be
installed between the MLCPU-1 module and the MLAD-1 module as shown
in Figure 3... -4.
Refer to the Installation Section earlier in this chapter for detailed installation
instructions for installing the Module into the System Base.
Configuration of the MLIM-5-2400:
The presence of a MLIM-5 is detected automatically by the OMP-MODL
upon power-up. No additional software or hardware configuration of the
module is necessary.
Telephone Line Connection:
A standard voice grade telephone line can be used with the MLIM-5-2400.
The two phone conductors (tip and ring) can be connected to the MLIM-5-
2400 via the modular phone jack on the end of the module. Polarity is not
critical for either connection method.
