(a) Transmission speed setting (SW09 to SW12)
Set the transmission speed (SW09 to SW12) as
follows.
The transmission speed setting must be consistent
with that of the GOT side.

*1 Only transmission speeds available on the GOT side are
shown.
*2 When the software version of AJ71QC24 (-R2/R4) and
A1SJ71QC24 (-R2) is "L" or earlier, and when 2 devices are
connected to the two interfaces individually, make the setting
so that the total transmission speed of the two interfaces is
within 19200bps.
When the total transmission speed of the two interfaces is
within 19200bps, a controller other than GOT can be
connected to the computer link module.
When only one device is connected to either of the
interfaces, a maximum transmission speed of 19200bps can
be set to the one where the device is connected.In this
instance, set SW09 to SW12 to "OFF" on the other side.
*3 When 3 devices are connected to the two interfaces
individually in the case of AJ71QC24N(-R2/R4),
A1SJ71QC24N(-R2), and A1SJ71QC24N1(-R2), make the
setting so that the total transmission speed of the two
interfaces is within 115200bps (within 230400bps in the case
of A1SJ71QC24N1(-R2)).
When the total transmission speed of the two interfaces is
within 115200bps (within 230400bps in the case of
A1SJ71QC24N1(-R2)), a controller other than GOT can be
connected to the computer link module.
When only one device is connected to either of the
interfaces, a maximum transmission speed of 115200bps
can be set to the one where the device is connected.In this
instance, set SW09 to SW12 to "OFF" on the other side.
*4 This can be set only in the case of AJ71QC24N (-R2/R4),
A1SJ71QC24N (-R2) or A1SJ71QC24N1 (-R2).
