Set the output frequency (ms) for read request and write request.
If remove the check for read request, set the sending cycle of the External Device
parameter group (PG).
Cycle Rate
Set the resolution of [Cycle Rate] in increments of 5ms. For example, do not set 1 to 4.
If the cycle is 0, the command is issued on the Display screen update cycle or D-Script
operation cycle.
Select this check box to enable read-modify-write.
The parameter group (PG) consists of multiple suspect parameters (SP), but
communication is performed in parameter group (PG) units.
When writing to a suspect parameter (SP) with read-modify-write enabled, after reading
the parameter group (PG) unit, only the area corresponding to the suspect parameter is
Read Modify Write
updated and written back to the parameter group.
When this check box is cleared, the previously written value is used and only the area
corresponding to the suspect parameter is updated then written to the parameter group.
When the Display is rebooted or enters offline mode, the previously written value is reset
to 0.
Either prevents or allows output of read request. Select this check box to allow output of
read request.
When preventing the output of read commands, the read value is not updated until the
Read Request
External Device issues a write request.
Additionally, even if you prevent output of read request, if read-modify-write is enabled,
the read request is issued immediately before the write request is issued.
Either prevents or allows check receive cycle rate.
To allow the check receive cycle rate, clear the [Read Request] check box and set the time
in [Cycle Rate].
Check receive cycle
The check receive cycle rate monitors whether the parameter group (PG) sent by the Exter-
rate
nal Device can be received within twice the time set in the [Cycle Rate]. If the parameter
group (PG) cannot be received within the monitoring period, an error message (RHxx133)
appears on the Display and the ERR LED lights up on the J1939 unit.

• If the [Cycle Rate] is 250 ms or less (excluding 0), the monitoring time is 500 ms.
• Error message RHxx133 is displayed if only the Display, for monitoring the receive cycle, is
activated. Start the Display after starting the External Device communication. Use the [Start
