Dear valuable customer, as we are located in Singapore, the price offered here is based on ex-Singapore.
We have to add in the freight and shipping insurance cost for delivery to your home country , but excluding your local tax , duties etc if applicable.
However if you plan to self-collect in our store, this is most welcomed, we have to add in Singapore 7% GST (Goods and services tax) over the total purchase.
This amount can be refunded at our Changi International airport, if you visit us as a tourist. Note that this GST refund is applicable only if you depart within 30 days
from date of purchase.
We strive to let you enjoy the purchase from us and have a wonderful experience with Expandore.

 Description

4-Wire Interface with Call Signal, Matrix-to-Party-line

The EF-701M interface converts a single channel of standard or TW party-
line intercom to four-wire audio, while also converting call signals to RS-422
data (and back). The resulting four-wire audio plus RS-422 data can then
be sent to a Clear-Com Matrix port, fiber-optic converter (modem) or
connected to another EF-701M over twisted-pair cable such as CAT-5E
