CONNECTING THE OPTIONAL “ELSA” BRAND MODEM

Raypak recommends the ELSA Microlink 56k modem for data communication. This modem will work with RayTemp and technical support will be provided if this modem is installed with the cor- rect cables. Raypak will not be able to provide support if you use other modem brands or build your own cables. In either case we strongly recommend that you test the RayTemp/modem con- nection in your office before installing the system. If possible, plan ahead, and have the phone line/jack installed about two feet from the heater. Secure the ELSA modem and connect the phone cable (that comes with the modem) from the wall jack to the ELSA modem jack labeled “Line”. Connect the RayTemp cable 5-423 from the modem’s 8-pin connector to the RayTemp’s “Serial to RJ11” adapter then connect the six-line data cable from the adapter to the RayTemp’s six-pin “RJ11” port (see figure below). Plug in the modem’s power transformer and turn on the power switch. Testing is covered in the next chapter.

CAUTION!

DO NOT connect a live phone line directly to the RayTemp control.

Doing so will damage the internal communication circuit!
