5.2.5 Job Processing

Both ports can be used independently from each other (multi tasking).

A possible initialization conflict will be solved as follows:

MVI46-S3964R has "High Priority":

The MVI46-S3964R retries the sending of the 3964R start character (STX) 3

times and waits for the CP to send the 3964R acknowledge (DLE). If the CP

does not send the acknowledge as expected the communication will fail and has

to be restarted.

MVI46-S3964R has "Low Priority":

The MVI46-S3964R rejects its send job and sends the 3964R acknowledge

(DLE) to the CP.

Important: If the MVI46-S3964R has rejected its send job due to "Low Priority", you must restart its

send job completely (starting with the copying of the job data).

5.3 Cable Connections

The application ports on the MVI46-S3964R module support RS-232 and RS-422

interfaces. Please look at the module to ensure that the jumpers are set correctly

to correspond with the type of interface you are using.

Note: When using RS-232 with radio modem applications, some radios or modems require

hardware handshaking (control and monitoring of modem signal lines). Enable this in the

configuration of the module by setting the UseCTS parameter to 1.

5.3.1 RS-232 Configuration/Debug Port

This port is physically an RJ45 connection. An RJ45 to DB-9 adapter cable is

included with the module. This port permits a PC based terminal emulation

program to view configuration and status data in the module and to control the

module. The cable for communications on this port is shown in the following

diagram:
