MIPRO ACT-818 Wideband Single-Channel Digital Receiver - Manual (Page 14)

! Plug one side of the supplied telephone-type cable (RJ-11 connectors) to the
REMOTE OUT socket of the on the rear of the receiver and the other end of the
cable to the REMOTE IN socket on the rear of the second receiver. Repeat this
connection for each receiver in the system as per the illustration above. Finally,
connect the REMOTE IN socket on the rear of the first receiver to the MIPRO-
DVU or MIPRO-DVJ.
! The system can link, monitor and control up to 64 receiver channels
simultaneously.
! The connection cable to the computer can be up to 300 metres (330 yards) in
length. However, signal stability and data transmission speed decreases as cable
distance gets longer. RF it is recommended not to exceed 100m (110 yards) to
maintain the highest data quality as well as a high transmission speed.

1. MIPRO ACT receivers are fitted with an ACT-BUS interface to enable remote control
and monitoring via a PC-based control system. To enable this to communicate, an
optional MIPRO interface adapter and software package is required.
2. Wiring Instructions
! Network interfacing of the ACT-818/ACT-828 receivers is achieved via the
REMOTE IN of the Network Interface Connector. This enables the receiver(s) to
be linked to a computer using a MIPRO-DVJ (Serial) or MIPRO-DVU (USB)
interface connector. Using the RS-232 or USB connector, you can link to a
computer through the RS-232 COM port or USB port. (See diagram below)

General Tips for Improving System Performance
! Since the installation of the antenna influences the operating efficiency of the
receiver, the most important rule is to minimise the distance as much as possible
between the receiving antenna and the microphone for the best reception and
performance.
! Use MIPRO supplied antennas to ensure proper receiver sensitivity.
! A built-in worldwide approved switching power supply assures stable performance in
the range of 100-240V AC mains power input.
! The antenna socket provides an 8V DC biased output. RF, shorting the antenna
socket should be avoided. Temporary shorts on the antenna socket will not affect
system performance (provided the short is removed), however, a continuous short
on the socket may cause permanent system damage.
! If extended reception distance is required, installing a MIPRO wideband active
directional antenna kit (AT-90W) will increase antenna performance and thus achieve
better range.
! Proper antenna distribution is vital to achieving ideal performance from multiple
wireless systems operating in the same environment. To greatly reduce antenna
clutter in multi-system installations, a MIPRO AD-707a UHF wideband antenna
divider system is recommended. Each AD-707a supports up to four UHF diversity
receivers to operate from a single pair of antennas. When combined with an AT-70A
omni-directional extension antenna and an AT-70B antenna booster or an AT-90W
wideband active directional antenna, the AD-707a antenna divider provides optimal
signal reception with minimal dropouts or interference. Note that the AD-707a
antenna divider must match the same band designation (7A,7B,8A,8B etc.) as the
receiver to ensure proper operation.
! MIPRO's factory preset “interference-free” channels within the same channel group
are recommended to ensure optimum performance from multiple wireless systems
installed in the same venue. Use of preset “interference-free” channels from
different channel groups may cause interference due to intermodulation issues, and
is therefore not recommended.
