Mounting Steps
Refer to the installation drawings in Figure 5 and the wiring diagram in Figure 6.
1. Determine the desired location and prepare the mounting surface, providing the
necessary mounting holes shown.
The OEM Receivers are provided with 3 mounting holes for 4-40/M3 mounting
hardware, and should be mounted with spacers/standoffs to provide .219”
minimum clearance between the PCB surface and the mounting surface. PCBAs
may be mounted on any suitable hardware, including screws with standoffs, PEM
Standoffs, PEM studs with standoffs, etc.
2. Mount the OEM Receiver. The 3 mounting screws pass through both the OEM
logic card and the Radio, securing both at the same time.
3. Check and configure the power select switch S3-p6.
4. Connect the VDC Power and the DMX data cables. The DMX connector (J4)
and VDC Power connectors are on the back of the PCBA. See Figure 6, below.
5. Connect the antenna cable.
CAUTION:
The antenna connector is fragile. Do
not bend or twist! Push the connector straight on to connect, and pull it straight
off to disconnect. The PCB mount antenna connector may break off the PCB if
twisted or bent.
6. Check all connections.
DO NOT CONNECT THE MAIN POWER SOURCE TO
THE OEM RECEIVER UNTIL ALL CONNECTIONS AND S3-P6 SETTING
HAVE BEEN MADE CORRECTLY!
