5.1 Preparations Before Use
5-6 ZM2371/ZM2372
Data rate
The RS-232 data rate setting menu is as shown follows.
RS-232 Data rate: 9600bps Current setting
0)4800 1)9600 2)19200 3)38400 >NEXT Options (first page)
4)57600 5)115200 6)230400 <PREV Options (second page)
Perform the EXIT operation to return to one-previous menu.
If the data rate is set, the result is displayed for a moment, and one-previous menu comes
back.
The data rate is common to the transmission and reception.
Select the rate at which the communication can be made stably within the data rate range
provided by both ZM2371 / ZM2372 and controller. Even if a selection is made, when the data
rate exceeds 19200 bps, stable communication may not be performed due to the restrictions
of cable. For high speed communication, a short cable having low capacitance should be
used.
Message terminator
A terminator indicating the termination is required at the end of a set of commands or
response.
The RS-232 message terminator setting menu is as shown below.
RS-232 Terminator:LF Current setting
0)CR 1)LF 2)CR LF Options
CR Uses one character CR (Carriage Return) as a terminator.
LF Uses one character LF (Line Feed) as a terminator.
CR LF Uses two characters CR and LF as a terminator.
Perform the EXIT operation to return to one-previous menu.
• When ZM2371 / ZM2372 transmits data
The set terminator is added at the end of response message.
• When ZM2371 / ZM2372 receives data
The command is executed when CR or LF, whichever comes first, is received.
If the message terminator is set, the result is displayed for a moment, and one-previous
menu comes back.
