CardMaster's new module communications option makes new installations easier. it also facilitates easier retro-fitting the modules to existing CardMaster fueling sites.  The modules come in three choices:  internet/cellular (75% of our communication option sales); Ethernet (local area network) modules represent about 24%; and RF less than 1%.  See the picture to your right showing the three sections of this modular approach.  


CardMaster is offered with a variety of communications options. These modules are all available for retro fit applications, as well as new sites.  Modules reduce field labor, and are less complex to install. From the factory & customer standpoints they also significantly reduce lead time from order receipt to shipping.          

CM-VICM CardMaster's most recent innovation is our "Internet/Cellular" modem in module form. 

With this service the CardMaster is accessed directly from a PC (office, home, hotel room, etc) through an internet link.  Access can be on any or all of the PC's in the office if desired, at no added cost.  The internet link connects to our remote secure server, which in turn transparently accesses the CardMaster cellular modem. our coverage is almost all of the US and Canada.  please ask, and we will verify your location has good coverage


CM-LANM CardMaster can be supplied with a module for Local Area Networks and Ethernet.  

Normally LAN modules are limited to 350' of cabling between modules. you can use CM-LANM for Ethernet connections, and local area networks.

CM-RFM To avoid trenching and conduits for serial communications we offer the alternative of RF (radio frequency) communications.  The "sending" RF module is installed to the CardMaster.  The "receiving" modem mounts on the wall of the building.  A serial cable is run from the "receiving" module to the PC. You may want to compare this with the CM-VICM above, also "wireless".
