The SynScan
TM
AZ telescopes are designed to receive control commands sent from a computer
via the RS-232 port and RS-232 cable. Once connected, the SynScan
TM
AZ can be controlled by
most popular planetarium software program. The SynScan
TM
AZ will communicate with the
personal computer at 9600 bits/sec, no parity and stop bit. All angles are communicated with 16
bit angle and communicated using ASCII hexadecimal.
