RS-232 Control
4
The RS-232 port on the back of an E Desk unit is set to a default baud rate of
38400, 8 data bits, no parity, 1 stop bit, and no flow control. (38400:8:None:1). If
multiple E Desks are connected together in a system then only one RS-232 port
needs to be connected to a third-party control system; communication data is
shared via Ethernet through a switch.
When controlling multiple E Desk units that are not part of the same DAP file,
each E Desk unit will need to be addressed via its own RS-232 port from a
control system or PC. E Desk units cannot be linked together via RS-232, like
some other WHIRLWIND Advantage products can.
(The RS-232 baud rate can be set to 9600, 19200, or 38400 – default is 38400)
A straight through PC Serial Cable is used to communicate from an RS-232 port
on a third-party controller (or PC*) to the RS-232 port located on the back of an E
Desk unit.
(* A PC can be used with a terminal emulator program, such as HyperTerminal
etc, to send/receive ETP Strings…E Desk software must be connected via
Ethernet in order to communicate.)
