3... INTERFACE MODULES

MLIM-5-2400; PCMCIA AND 2400B MODEM MODULE

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.
