BIN: (Binary) Enter a leading B, then any valid combination
of 1s and 0s. The data is right justified if less than 16
bits are entered.
The WRITE function will then display the current values of all registers
located at the specified slot with the following headers:

5.2 Remote Heads (M/N 57C328, M/N 57C329,
and M/N 57C330)
There are five commands from the terminal that are recognized by
the Remote Heads: T, S, C, R, and W. These commands are
described below.
5.2.1 Self Test (T)
Entering T" initiates the powerĆup sequence and the selfĆdiagnostic
test of the Remote Head. This command is valid only if the line is
inactive, i.e., no communication is taking place on the Remote I/O
network. Therefore, it can be used to recognize a new drop number
(using the thumbwheel switch) without cycling power to the Head.
5.2.2 Status (S)
Entering S" will display at the operator's console all the parameters
associated with the module. All line statistic parameters (other than
PORT RETRIES) will increase to 65535 and then roll over to zero. All
drops will display the following status information:
SOFTWARE PART NUMBER 419451Ć1nnx
(nn is the part version number; x is the part revision number)
LINE IS ACTIVE or INACTIVE
DROP NUMBER 1 through 7
MESSAGES RECEIVED: n
RECEIVE TIMEOUTS n
CRC ERRORS n
OVERRUN ERRORS n
ABORT ERRORS n
MESSAGES SENT: n
LAST RESET: zz
PORT RETRIES (P0, P1, P2, P3): n, n, n, n
where:
MESSAGES RECEIVED is the total number of messages received
by the drop. While the line is inactive, this value will remain
unchanged. While the line is active, it will constantly increase in
value.
RECEIVE TIMEOUTS is the total number of timeouts that have
occurred while the drop was waiting for a message to be
received. While the line is inactive, the slave drop will indicate a
value of 0.
CRC ERRORS is the total number of cyclic redundancy check
errors that have occurred since the last reset of the drop. This
number should ideally remain equal to zero.
