Mitsubishi Electronics GOT1000 manual 265

(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.

Setting			Transmission speed*1*2*3
	4800	9600		19200	38400	57600	115200

*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).
