Protocol selection
The PHC10-3 PLUS has two switch-settable command sets (basic command set and extended command set) offering different protocol
options. The command set selection is made using switch 9 on the rear panel.

Data transmission format is as follows:
1 start bit
7 data bits
1 parity bit (ignored on Rx: always 0 on Tx)
1 or 2 stop bits (switch 4)
Protocols: PHC10-3 PLUS RTS is asserted before first transmission from the head and remains asserted. If switch 5 is UP, CTS must be
asserted by the CMM computer to allow the head to transmit. If switch 6 is UP, the PHC10-3 will add an ASCII LF character to every
transmitted message.
