Manually Formatting the Module

Manually formatting the module does not require

communication with the module. Use this procedure as a

last resort when there is no communication with the

module. Although down-loading memory overwrites all

existing memory, it requires communication in order to

initiate the transfer.

WARNING: Formatting the module erases all

transferred memory. The Transferring Memory

procedure must be followed after formatting.

Turn the R683's power switch OFF.

Set all eight of the R683's address and baud rate dip

switches to the ON position (see Figure 1 for

location).

Turn the R683 module's power ON.

Watch the LEDs on the R683 go through the

initialization process.

Turn the R683's power switch OFF.

Set the R683's address and baud rate using the 8-

position dip switch (see Figure 1 for location).

Turn the R683 module's power ON. The module is

now formatted.

The R683's LEDs are identified as follows (see Figure 16

for location):

Digital Output Status- lights when output is activated.

Error - lights when a software error is detected.

Run - Blinks to indicate R683 is powered and executing

correctly.

Transmit - lights when the R683 transmits data to the

CMnet or access port.

Receive - lights when the R683 receives data through the

CMnet or access port.

During power-up, the module goes through an

initialization and self test sequence. Proper module

power-up may be verified by observing the LEDs as the

module is powered ON.

Shortly after power is applied to the module, the

following sequence occurs:

The "Run" and "Error" LEDs will flash.

Both LEDs will pause.

The "Error" LED will turn off.
