The following three protocols are prepared as the communication
protocols between the remote buffer and host computer. The protocol can
be selected by a parameter according to the specifications of the device
to be connected.
Protocol Features Interface
Maximum
transfer rate
Protocol A Handshake method. Sending and re-
RS–232–C 19200 BPS
ceiving are repeated between two sta-
tions.
RS–422 86400 BPS
Extended
protocol A
Similar to protocol A. Enables high–
speed transfer of the NC program to
meet high–speed DNC operation.
RS–422 86400 BPS
Protocol B Controls communication with control
RS–232–C 19200 BPS
codes output from the remote buffer.
RS–422 86400 BPS
NOTE
The average data transfer rate is lower than the maximum
transfer rate.
