4.2.2. Default Handshake (Sw4, Sw5)
SetUp Switches four and five select the default handshake format
for RS232 Ports One through Seven. The default handshake
format must match the format your control device will use when
communicating with the APS. SetUp Switches four and five can
select RTS/CTS (hardware), XON/XOFF, Both or None.
Notes:
·
If the control device will communicate with the
APS-8M via an external modem connected to one
of the RS232 ports, select a default handshaking
format that is compatible with the external modem.
·
The /P command can also be used to select a
different handshake format for each port.
·
Setup Switches Four and Five do not select the
default handshake format for Port 8 (the Internal
Modem Port). The default handshake format for
Port 8 is RTS/CTS. The operating handshake
format for Port 8 can also be set via the /P
command.
