Use option 6 in Figure 1 to set the
PGN Repetition Interval
which is described in more detail in the section—J1939 Data
Frame Structure
Use the
Toggle Proprietary or Joystick Messages (BJM/EJM)
, option 7, to toggle the type of messages transmitted by
R170. The R170 can transmit either Proprietary messages, as described in section—J1939 Data Frame Structure, or
SAE J1939-71 Joystick messages, as described in the SAE document Vehicle Application Layer – J1939-71 (through
2001), Revised 2003-12.
If the R170 is configured to transmit SAE joystick messages then use
Configure Joystick Messages
(option 8) to con-
figure the mapping of OMNEX analog and switch/button values to joystick message fields.
NOTE: You must set the transmitter ID before configuring the mapping (see section Downloading Transmitter ID in the User’s Manual).
NOTE: There may be other devices in a J1939 network, which use PGN 65280. Therefore, ECUs should match the SA to entries in
its NAME table to ascertain whether a particular PGN 65280 frame originates from an OMNEX R170. The NAME of the R170 is given
in Table 1.

Table 1
R170 J1939 NAME Fields
The other items in the menu affect the R170’s J1939 NAME on the J1939 network. A J1939 node name is 8 bytes long
and in the R170 is defined as shown in Table 1.
Each node on a J1939 network must have a unique name. To facilitate this, the R170’s J1939 name is dependent on
the transmitter ID downloaded from an OMNEX wireless transmitter. The transmitter ID is labeled on the OMNEX trans-
mitter.
When the J1939 CANBUS Setup Mode is exited, the R170 will re-initialize with the new J1939 NAME and continue
normal operation.
In proprietary message mode, the R170’s J1939 interface (CAN1) cyclically outputs PDU2 frames containing the OMNEX
command values from an OMNEX transmitter. Table 2 shows the contents of each frame. The default transmission pe-
riod is 10 milliseconds but this may be changed via the J1939 CANbus Setup Menu.
