DETAILED DESCRIPTION:
CCHN(type,channel) closes the specified communications channel, where "type" is the
communications mode, and "channel" is the COM port to close. This command flushes the
serial port buffer — any characters in the buffer will be lost.
For a D-style motor, the channel 0 COM port can only be RS-232 or RS-485, while channel 1
can only be RS-485.
For an M-style motor, only the channel 0 COM port can be opened. It is only RS-485.
The following are valid CCHN commands:
CCHN
(
RS2
,0)
'Close the channel 0 RS-232 port
CCHN
(
RS4
,1)
'Close the channel 1 RS-485 port
After power up or a Z reset command, channel 0 is opened as RS-232 by default.
EXAMPLE:
EIGN
(W,0)
'Make all onboard I/O inputs
ZS
'Clear errors
CCHN
(RS2,0)
'Close main RS-232 communications port 0
