This parameter allows the baud rate for communicating with remote serial
devices to be set to either 9600 (0) or 2400 (1) baud. Each time Parameter
37 is changed, power must be recycled to the drive before the new baud
rate can be used.
The 9600 baud rate permits faster communications with remote serial
devices and reduces update time. The 2400 baud rate provides slower
communications, but improves communication accuracy with remote serial
devices. If communication errors occur or erratic data is displayed, the
slower baud rate should be used.
Serial devices are connected to the 1336-MOD-S1 Serial Port. The baud
rate of the 1336-MOD-G2 Remote I/O Adapter must be set to match this
parameter setting. The 1336-MOD-E1 Handheld Terminal and
1336-MOD-E2 Monitor Display, upon power up, automatically detect the
setting of the drive baud rate and do not need to be reset to match
Parameter 37.
