SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
eNfusion™ HSD-128 High-speed Data Terminal
Note: MSB is the Most Significant Bit and LSB is the Least Significant Bit.
(h) Remote Status Panel – Multi-Channel (Optional)
An optional “remote status panel” may be installed in installations where the HSD
and/or any HSD-X units are located in inaccessible or remote locations. The
installation of a “remote status panel” is recommended as it provides visual
indications of each of the power, fault, and call status of each of the units.
A “remote reset switch” for HSD transceivers can also be installed and located
with the Remote Status Panel.
Figure 3–19 illustrates a typical wiring diagram
for the remote reset circuit.
Note: HSD-X transceivers DO NOT support the use of the reset function.
1. HSD Remote Reset Switch Circuit Requirements
HSD transceivers support the installation of a Remote Reset Switch circuit
as shown in
Figure 3–19.
The HSD Remote Reset circuit requires less than 100 ohms between TP1K
(RESET) and MP1F(COM) to be asserted and greater than 10 kilohms to be
de-asserted (include all cable and switch contact resistance).
2. HSD Remote LED Driver Circuit Requirements
The circuit requirements for the HSD Remote Status LED drivers are shown
in
Figure 3–20. Each LED driver circuit has a 200-ohm current limit resistor.
The maximum cable resistance (including the forward and return paths) must
not exceed 100 ohms to provide adequate current to the 5 volt LEDs (i.e. 10
mA minimum) at the remote status panel.
It is recommended that the installer use shielded cables to provide a level of
noise immunity.
3. HSD-X Remote LED Driver Circuit Requirements
The HSD-X unit’s Remote LED drivers are shown in Figure 3–21. The open
collector transistors located in the HSD-X are capable of driving up to 500
mA of current—so either incandescent lamps or LED circuits with the
appropriate current limits can be used. The example shown in
Figure 3–21
shows an LED powered with a 28-volt source.
