Supported Interfaces QTERM-G70 Terminal

Qlarity-Based Terminal Hardware
1.2.5 Optional Dual and Quad EIA-232 Serial Port Card
An additional two or four EIA-232 serial ports can be added to the QTERM-G70. These serial
ports have all necessary signals for EIA-232 serial communications and are wired as
Data Terminal Equipment (DTE).
The additional serial port option will add approximately 10 mA to the total current draw of the
terminal plus 15 mA per connected serial cable.
The following table shows the pinouts for the additional serial port option.
1.2.6 Optional Power-over-Ethernet Module
The optional Power-over-Ethernet module allows the user to provide power and communica-
tions to the QTERM-G70. The power can be provided from an IEEE 802.3af compliant hub or
switch as well as from a standard power supply.
1.2.6.1 Power Requirements
The optimal power supplied to the QTERM-G70 through the PoE port is 48 VDC, although
the unit will operate with a power input as low as 36 VDC, or as high as 57 VDC (see IEEE
802.3af specification). The power required to operate the terminal without any additional
options is listed below.
