bits is required)
A.5 Delay Setting with RS-422 Control Port
This method uses the RS-422 control “port” to change the delay value. The control port is part of the
physical external timing input connector. Table 2-10 shows the MA-215/MA-217B/MA-235-1/MA-235-2
timing in port pin assignments.
The control port is a receive-only RS-422/RS-485 serial port configured to accept an asynchronous
9600 bps data stream with these elements:
●
One start bit
●
Eight data bits
●
No parity
●
One stop bit
The control port recognizes four different information bytes. Each of these four bytes consists of two
identifying bits and six data bits (Figure A-2); the 24 data bits contained in these four bytes are
identical to the 24 bits in P02, P03, and P04 under ISiCL (Section A.1 –
Delay
P Codes
). The least
significant (right-hand) bit is transmitted first. As when using P codes, it is best to send the most
significant bits first.
