Connect the UIC to a receiver
-
Using a customer supplied wiring harness, connect the UIC serial port to a serial port on the OEM7 receiver. See UIC Connectors 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.
COM Port Recommendations 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 Connecting Data Communications Equipment 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.PwrPak7
COM1 and COM2 on the PwrPak7 can use RS-232 levels (default) or RS-422 levels. To use COM1 or COM2 for connection to the UIC, use the SERIALPROTOCOL command to configure the COM1 or COM2 port to use RS-422 levels.
COM3 on the PwrPak7 uses RS-232 levels. To use COM3 for connection to the UIC serial port, an interface circuit that converts to and from RS-422 levels is required.
