Out of the Box – Quick Start
The DCB-274 is supplied with mating motor, power supply and I/O connectors. The SIN-(n) (chosen serial
adapter) is supplied with a mating cable and terminator, if required.
Equipment Check List
1. A computer with available serial port.
2. Installed serial communications software such as Hyper term, EASI, ProComm, etc. (EASI works
with DOS).
3. A DCB-274.
4. A SIN-(n) serial adapter (SIN-10 recommended).
5. A +24* to 40Vdc power supply with adequate output power.
6. A compatible stepper motor.
7. A DC Amp meter with bridge rectifier circuit.
8. A cooling fan or heat sink as necessary.
* The DCB-274 will operate at voltages of 12Vdc minimum, but it is not recommended due to the lower
performance and higher power supply amperage demand.
Preliminary Settings
-SIN-7 or 9 (non configurable)
or
-SIN-8 (place red selector switch in “S” (single) position)
or
-SIN- 10 (all (8) switches in off position- towards DB-9 connector).
-DCB-274: Remove any baud rate jumpers.
Basic Set-up
1. Connect the SIN-(n) adapter to serial input (J2) of DCB-274 with RJ-45 cable.
2. Connect the SIN-(n) DB-25/9 end of the serial adapter to the computer RS-232 serial port.
3. Connect your power supply to the power connector (J5). J5-pin 1 is negative (GND). J5-pin 2 is
positive (+) VMM. Improper power connection will destroy the electronics. GND is also connected
to the base plate
(Motor connection is not necessary at this time).
Configure Serial Communications
Full duplex, 9600 baud, no parity, 8 data bits, 1 stop bit.
Note: <CR> is the enter key.
Apply Power
Less than 0.1 amp is drawn (for metered supplies).
Depress the SPACE BAR key and the DCB-274 should sign-on.
Troubles
1. Nothing happens:
a. Check connections.
b. Check for correct COM port.
c. Check switches.
d. Inspect RJ-45 connectors for bent contacts.
2. Garbage characters appear:
a. Verify baud rate and serial parameters.
b. Check the RJ-45 connectors/cable ground continuity.
3. “GO-SS conflict” message appears on screen.
a. Make sure the three-pin PLC jumper is in the standard mode (pins 1 and 2 installed).
