Modem Port - Acroprint Data Collection Terminal DC7000 Hardware Manual

Modem Port

The port depicted may have either an RS-485, a Modem, or an Ethernet
Communication Device. Terminals, which are equipped with a Modem
port, will not have an Ethernet or RS-485 port. The Modem Port is a 6
position 4-pin female port, which will accept a male RJ-11 modular
connector.
The internal modem (modulator/demodulator) converts electronic data
into tones, which are then transmitted over phone lines.
Warning: Connecting to a digital phone system will damage the
modem and void the warranty.
