HMX Specifications

Communications Bus: The communications bus conforms to the RS-485 standard and requires the use of
UTP- cable for 1M Baud data rates. Wiring must be run in conduit in a daisy chain from the Master Panel to
the first Dist. Panel, from each Dist. Panel to the next Dist. Panel and from the last Dist. Panel back to the
Master Panel. When style 7 wiring is used, a separate conduit for each bus must be used.

Voltage: 5V peak-to-peak max.
Current: 50mA max.
Impedance: 120 Ohms
(max. imp. between panels)
Frequency: 1.024MHz

Power Requirements: Power supplied to the DCC module is routed to any attached peripherals. These
peripherals in turn determine whether the DCC is part of a Master Panel or a Dist. Panel.. Amplifier modules
in Dist. Panel are powered separately.

Battery Charging
Maximum charging current from EVX-25/50 is 800mA.
Maximum battery size* is 18Ah for EVX-25E and EVX-50E.
Maximum Battery size* for EVX-100E is 24 Ah.
* 12 amp hour is maximum size that will house in a MP or DP cabinet
