1.0 APPLICABLE DOCUMENTATION
The information contained in this supplement is applicable to the Micro-DCI® Instruction Bulletin
53ML5100A, Manual Loading Station.
1.1 SCOPE OF CHANGES
The 53ML5100 Manual Loading Station now has Datalink capabilities as a result of Revision 1 to the firmware EPROM. In a Datalink network, nodes communicate as responders to host personal co mputer queries. The host personal computer functions as the interrogator and acts as the central control point for the
Datalink network. A maximum of 32 addressable nodes can be connected to a Datalink network. With this
firmware revision, a 53ML5100 Manual Loading Station can function as a node instrument on the Datalink
network.

2.0 INSTALLATION PROCEDURES
Reference Micro-DCI Instruction Bulletin 53ML900, Upgrading the 53ML5100 Manual Loading Station, for
instructions on installing the new EPROM on the main board.
Datalink is an interrogator/responder serial interface capable of supporting 32 instruments on a single network. It uses an RS485 physical interface. See the Datalink wiring diagram for this instrument in
Figure 2-1.
The interface for connecting the 53ML5100 Manual Loading Station to a Datalink network is via the rear
terminal board (TB1), pins 19 through 22 (T+, T-, R+, and R-).
The Datalink interface requires four conductors: a transmit pair (T+, T-) and a receive pair (R+, R-). The
voltage levels of each conductor pair conform to the EIA RS-4 22/485 standard. In accordance with this
standard, the overall Datalink network distance is limited to 4000 feet when #24 AWG twisted pair wire is
used to interconnect the nodes. Adapters are available to convert RS-422/485 to RS-232 or 20 mA current
loops.

4.0 DATALINK COMMUNICATIONS
Datalink communications capabilities are now provided in the 53ML5100 Manual Loading Station.
Datalink Information in this supplement can also be applied to the existing configuration port binary mode
as follows:
1. The configuration port data rate is still 9600 baud, with 8 data bits, and no parity.
2. The configuration port powers up in standard mode suitable for use with the HHC, but is
switched to binary mode by sending the following four character sequence:
Sent 03
Echoed 0DH 0AH 1BH 20H 0EH 20H 15
✎ Note Numbers used in this section that are expressed in hexadecimal
After echoing the 15H character , the instrument switches to binary mode and is able to process
binary communications messages from that time on. (Characters sent af ter the 15
the 15
echo are ignored.)
H
3. Once the configuration port switches to binary mode, it remains in that mode as long as the
connection is maintained. The connection is maintained by sending a character at least once
every 30 seconds. If 30 seconds elapse without a character being received by the instrument
through the configuration port, the port returns to standard mode.

4.1 Protocol
The Datalink protocol requires the host persona l comp u t er to initiate all transactions. There are two basic
categories for all of the Datalink message types: Interrogate, which is used to read data from an
addressed instrument, and Change, which is used to alter a value in an addressed instrument. The
addressed instrument decodes the message and provides an appropriate response. The protocol definitions for the Datalink message types are provided in Table 4-1.
Table 4-1. Message Field Definitions
Symbol Title Definition
SOH Start of Header This character, 7E, denotes the beginning of a message.
CMD Command Is the operation to be performed or a description of the message
that follows the Command-I.A. byte. The Command-I.A. byte has
two fields: the Command field (3 bits), and the I.A. field (5 bits).
There are five commands: Interrogate, Change, Change Bits ,
Acknowledge, Response. The commands are covered in Section
4.1.1, Message Types.
I.A. Controller Address The address of the instrument responding to the transaction. It must
be within a range of 00-1F (00-31 decimal).
NUM Number The number of data bytes transferred or requested. The NUM must
be in a range of 00-32 decimal.
LO-ADD Lower Address Bits The least significant 8 bits of a 16 bit instrument address.
HI-ADD Higher Address Bits The most significant 8 bits of a 16 bit instrument address.
DATA An 8 bit data byte.
XXXX Represents a variable number of data bytes.
MASK An 8 bit byte where each bit, called a flag, is dedicated to an event
that is permitted or prohibited, depending on the flag setting.
If the flag is set to 0, the event is permitted.
If the flag is set to 1, the event is prohibited.
STATE Represents the bit settings of a particular byte: which bits are set
to 1, and which bits are set to 0.
LRC Longitudinal
Redundancy
Character
Is a character written at the end of the message that represents the
byte content of the message and is checked to ensure data was not
lost in transmission. It is the sum of all bytes Modulo 256 of the
message not including the SOH character or its own bi t settings
(LRC).

4.2 CALCULATING DATA ADDRESSES
If communications software must be generated to accommodate unique Datalink applications requirements, then the instrument memory address scheme must be known for pro per data bit (e.g., L datapoint s)
and data byte (e.g., B, C, H, and A datapoints) memory location determination.
✎ Note Hexadecimal (base 16) numbers used in this section are identified
with a subscript
This memory address scheme applies only if a 6 is in memory address location 8002
location 8002
must be read and if it contains a 6, then the address scheme that is described in Table 4-2

should be applied for this instrument.

4.3 SOFTWARE CHARACTERISTICS
1. Transparency Rule - whenever 7E hexaecimal is transmitted as anything other than SOH,
a 00 byte will be inserted directly following it (byte stuffing).
2. All transactions are initiated by the host personal computer.
3. All instruments begin their response within 10 ms after th e end of the transmission by the host
personal computer; otherwise, a faulty transmission may be assumed.
4. Illegal messages received by the instruments are ignored.
5. The maximum number of data bytes per message is 20
4.4 HARDWARE CHARACTERISTICS
1. Transmission Speed - standard rates are 110 - 28800 baud.
2. Asynchronous by character.
3. A character is:
1 Start bit.
8 Data bits - the Least Significant Bit (LSB) is transmitted first.
1 Even Parity bit.
1 Stop bit.

4. The line is 4-wire, shielded twisted pair, type RS-422/485.
4.5 INITIALIZATION MESSAGE
If datapoints A188 and A189 are configured to NON-NULL values, their contents will be transmitted onto
the Datalink network at reset/power-up. Prior to transmitting, a delay based on the unit’s instrument
address is observed. There is a one second delay between the transmission of datapoint A188 and
datapoint A189 contents. Datapoints A188 and A189 can be configured as two NULL TERMINATED
strings up to 10 characters each. For example, to initialize a Hayes-compatible modem to Auto Answer,
datapoint A188 would be configured through the faceplate push buttons to appear as follows:
This seven-character string is an Auto Answer command that direct s the mo dem to respond to calls on the
fourth ring. It is an AT command that loads the modem S0 register with a 4 to indicate a modem response
on the fourth ring. Any value other than 0 in this modem register activates Auto Answer. The NULL
TERMINATING values are automatically propagated into the remainder of the datapoint field by the controller. Datapoint A189 can be left at all NULL VALUES for this operation.
