ERIAL
The serial port operates the same in all Accelnet Plus Micro Module models.
After a power-on or drive reset, the Baud rate defaults to 9600.
Thereafter, it can be set to a higher rate by setting ASCII parameter 0x90 to the desired
rate:
Common settings used are: 9600, 19200, 57600, and 115,300 (230,400 maximum) Baud.
After sending 0x90, the drive will reply immediately at the higher Baud rate so the sender
should wait some time (10 ms or more) before resuming communications with the drive
at the newly programmed higher rate.
AEV & APV RxD & TxD signal levels are 3.3 V LVTTL. For actual RS-232 voltage levels
external components are necessary. The AEZ and APZ models have these components on
the EZ boards and can connect directly to RS-232 sources.
