2.3.2 Connect the IMU to the UIC
1. If using an ISA-100C, attach the screw kit to the
IMU to UIC Interface Cable
.
2. Connect the
IMU to UIC Interface Cable
supplied with the UIC to the IMU. For IMU cables with screws,
secure the cable to the IMU using the screws.
3. Connect the
IMU to UIC Interface Cable
to the IMU connector (J1401) on the UIC.
2.3.3 Connect the UIC to a receiver
1. Using a customer supplied wiring harness, connect the UIC serial port to a serial port on the OEM7 receiver.
See
on page 275 for pinout information for the communications connector (J102).
The serial port on the UIC uses RS-422 levels.
To connect the UIC to devices that use other signals levels, such as an LVCMOS
COM port on the OEM7 receiver, an interface circuit that converts to and from RS-422
must be used.
OEM719
OEM7600
OEM7700
OEM7720
All of the COM ports on these receivers use LVCMOS levels.
An interface circuit that converts to and from RS-422 levels is required for the port connected
to the UIC.
OEM729
COM1 on the OEM729 receiver can use RS-232 (default) or RS-422 levels.
To use COM1 for connection to the UIC, configure the COM1 port to use RS-422 levels.
Refer to the
OEM7 Installation and Operation User Manual
for information about changing
COM1 to RS-422 levels.
COM2 and COM3 on the OEM729 receiver use LVCMOS levels.
To use COM2 or COM3 for connection to the UIC serial port, an interface circuit that
converts to and from RS-422 levels is required.
