545C Operations Manual

02/10/2012 Prerelease DCN 00001789-A

Data coming in from a passed-through port will not be passed to the

assigned protocol driver and will be sent out the “other” port of the

connection.

The connection can be turned off by entering PASSTHRU,OFF,n where “n”

is either port in the connection. In addition either port in a pass-through

connection can output the string PASSTHRU,OFF to close its own

connection. The first method can be used from the operator port to close a

connection of other ports. The second method is used by the operator port

if it is one of the ports in the pass-through connection.

If port 1 is assigned to a CR10X driver, and port 0 is the operator port, then

the command PASSTHRU,0,1 allows the operator port to be connected

directly to the CR10X. One can then use XTermW or PC208 to talk to the

CR10X via the operator port without re-connecting cables.

5.5.6 Internal Sensor Values

The new MCC-545C -03 and later radios have the capability to read a

number of internal sensor values. These include:

• Internal temperature of the MCC-545C unit

• Internal rechargeable battery level

• External battery levels (loaded and unloaded)

These sensor values can be read using the EVENT command – refer to

Section 4.6.8 for details on how to program the MCC-545C to read these

values.

5.5.7 Generic Data Logger

The MCC-545 family of RF Modems includes a set of device drivers for its

serial ports. These have been customized for various external devices,

depending on the device requirements. The SDATA command allows a

simple text-based interface to send data groups to the MCC-545C for

transmission to the master. Any customer who can configure their data

report to meet this format can interface their data logger with no change

in the MCC-545C software. From 1 to 16 groups can be input, and there can

be from 1 to 16 sensors per group. Each sensor data value is formatted into
