RS-232 Interface
The RS-232 interface appears on a DE9F connector on the rear panel. The connector is wired as
a DCE device. A command interpreter accepts ASCII commands (described in Appendix B) over
the RS-232 and Ethernet interfaces. The RS-232 port operates at 38.4 kbps, 8N1 (8 data bits, no
parity, 1 stop bit), with no handshake.
