Always set the port B communications protocol to CompoWay/F (0). When
using
, always keep pin 3 on SW2 turned OFF.
6-1-2
Unit Number Setting
The unit number is set first. The setting is made on SW1 and SW2 on the front
of the EJ1. For information on the setting method, refer to
1-1-4 Using Setting
Switches
.
6-1-3
Other Communications Settings
The communications baud rate, communications data length, communica-
tions stop bits, communications parity, and send data wait time are set using
communications. When using
, the baud rate can be set on SW2. Refer
to
6-4-2 Write to Variable Area
for the setting procedure. Use communications
with the default communications settings to change any of these settings.
Refer to
6-4-2 Write to Variable Area
for information on how to change set-
tings. When the above settings are changed, the changes will not be enabled
until the EJ1 is reset or the power is cycled.
6-1-4
Send Data Wait Time
The send data wait time setting is used to adjust the time the host computer
takes to switch from sending to receiving. Specifically, the send data wait time
for the EJ1 is the time from after a response has been created after data has
been received until the EJ1 switches to sending.
The setting of the Send Wait Time parameter can be shortened to reduce the
communications time at the host device as long as there are no problems.
