Can I use the modem in my PC/Laptop to communicate with a Data-Linc DLM4000 in the field?
The DLM4000 comes pre-configured from the factory to communicate effectively with PLC’s. To do this, it is necessary to set some of the registers in the modem in ways that differ from register settings that may be found in other modems. Because of this, connectivity with other modems may not be possible without changing the registers in the other modems. In some cases, it’s not possible. Because different modems have different register settings, it is difficult to determine ahead of time if a given modem will interface with the DLM4000. It is also worth noting that changing the register settings in the DLM4000 would inhibit its ability to communicate with a given PLC. The only way to assure reliable communications when using the DLM4000 is to have one at both ends of the connection. In the long run, it is the most cost-effective way to go. In any case, it is always best to contact one of the Data-Linc applications engineers to discuss your specific installation.
