MFC-CB™ Operation and Maintenance Manual

3.4.5.1 <1COM1> AND <2COM2>

The COMx ports can be set for the specific settings required by the user.

The settings are baud rate, parity, data bits and stop bits. The available options are

found in Table 5.

Table 5. CO

M1 and COM2 Available Settings

BAUD RATE

300, 600, 1 200, 2 400, 4 800, 9 600, 19 200

PARITY

NONE, ODD or EVEN

DATA BITS

7 or 8

STOP BITS

1 or 2

The default COMx settings are 2400, E, 7,1 for both COM ports.

The MFC-CB appends a carriage return (<CR>) and a line feed (<LF>) to all

messages that are sent out of the COM1 port to the host. It looks for a carriage

return to terminate incoming messages and ignores line feeds. The user MUST wait

for a reply to each message sent to the MFC-CB before sending another message to

it (see Section 4).

3.4.5.2 <3IEEE-488>

The IEEE-488 port address can be defined from 1 to 31. The default address is 10.

The MFC-CB sends a line feed (<LF>) and asserts the EOI line at the end of all

transmitted messages. It looks for a line feed and/or assertion of the EOI line to

terminate incoming messages (see Section 4).

3.4.5.3 <4RS232 SELF-TEST>

The RS232 self-test is provided to check the MFC-CB COM ports and the interface

cable independently of an external device or computer.

If you are having difficulty communicating with MFC-CB from a host computer

using RS232, the RS232 self test can help establish that the MFC-CB COM1 port

you are trying to communicate with and the interface cable you are using are good.

To run a self test of the RS232 ports (COM1 and COM2), press [SPECIAL],

<5remote>, <4RS232test>.

The display prompts you to connect COM1 to COM2 using a standard pin to pin DB-9

female to DB-9 male RS232 cable (see Section 4).

Once the

cable has been installed, press [ENTER] to run the self-test. The test is

first executed in the COM1→COM2 direction and then in the

COM2→COM1 direction.

If the COM1→COM2 test passes: <PASSED> displays briefly and the test

proceeds to COM2→COM1.
