VMM-T1 User Manual

RS-232C Operation 

The 

VMM-T1

 inputs can be controlled via an RS-232C computer serial signal (COM port).  From the 

computer’s RS-232C serial port, connect a cable such as the Model 

910RS 

(not supplied), the 

910RSDC 

(not supplied), a

 null modem cable

, or a user-constructed cable (with connections as enumerated in the 

INPUT SPECIFICATIONS) to the unit’s RS-232C interface. 
Connect the Tx (transmit) from the host to the Rx (receive) on the 

VMM-T1

 control unit.  All other 

lines are not used except for the ground connection.  If the host contains a 25-Pin D-Sub or an 8-Pin 
Mini-DIN, check the computer’s user manual to find the proper corresponding pin-outs.  In most cases 
the corresponding 25-Pin D-Sub pin-out and MAC 8-Pin Mini-DIN are as follows: 

 

Function 

VMM  

DB-9F 

IBM  

DB-9M

DB-25M 

MAC  

Mini-DIN-8F 

VCM

Rx 

Receive Data 

Tx 

Transmit Data 

GND  Signal Ground 

General Pin-Outs for 25-Pin D-Sub and MAC 8-Pin Mini-DIN 

 
All other pins not used.  Be sure to connect the Tx pin, Pin 3, from the IBM 9-Pin D-Sub (or Pin 2 from 
the 25-Pin D-Sub) male connector to the Rx pin, Pin 2, of the 

VMM-T1

 9-pin D-SUB female connector, 

located on the rear panel, for proper operation.  Connect all other functions by type as indicated above.  
By sending the proper commands the unit will respond by activating the proper functions. 
The 

RS-232C Test Program 

listed elsewhere in this manual will allow operation of the VMM-T1 from 

the computer keyboard. 
Activation of the EXPOSURE and DELAY times with a TRIGGER command through the RS-232C 
interface can be de-activated as follows:  

a.

 

RESET command from the control unit's front panel 

b.

 

Through the RESET INPUT BNC on the rear panel 

c.

 

Reset command through the RS-232C 

When an open command is sent to the 

VMM-T1

 controller, a RESET command will 

not

 close the 

shutter.  The shutter must be closed with a CLOSE command.

  The 

VMM-T1

 controller trigger 

command from the RS-232C is utilized to trigger the built in timers.
