THUMBWHEEL SWITCH
To connect a SMC40M -TWS7seven decade thumbwheel switch, simply connect the cable that is included
into the expansion input slot on the Driver Pack. The SMC40M -TWS7 expansion module is used for
register manipulation or math functions. ( Purchased Separately )
EXAMPLE 1:
Example 1 demonstrates the SMC40 reading the
first thumbwheel module(A) value dialed. If three
modules were in use, refer to them as A,B,C
where the furthest that is multidropped is C.
EXAMPLE 2:
Example 2 demonstrates the Result Register equal to first thumbwheel module(A) value dialed. A math
function is performed with the value and set equal to another temporary register R1. Then the distance
number is set equal to the temporary register
value R1.
Connect the SMC40M -TWS7 (maximum of three) to the SMC40 through a standard telephone handset
cable (on J2) - no external power supply required. J1 is the Input socket and J2 is the Output socket for the
next module. If used in conjunction with the SMC40M-24I Input Module, simply multidrop the thumbwheel
switch module(s) along with the input module(s).
REMOTE PANEL MOUNT
The SMTNR2-1 is an ASCII terminal for use with the SMC40 Indexer (Purchased Separately).
TheSMTRN2-1 features a 20-key keypad with tactile feedback and a liquid crystal alphanumeric display
showing 4 lines of 20 characters. The terminal provides user selectable communications parameters,
programmable function keys, and other features which make it ideal for industrial applications requiring
flexibility and solid, reliable operation. When properly mounted between the terminal face and panel, the
gasket provides a NEMA 4/12 rating. (Dimensions4.9 x 4.9 x 1.43)
The purpose of the remote panel mount can be to operate large scale programs without the need to
introduce a PC or an alphanumeric terminal. This allows the operator to enter run time data.
Installation
(WARNING: Never Connect the RS232 Cable and SMTNR2-1to the SMC40 Indexer simultaneously.
A six pin modular connector is provided and used to connect to J1 of the SMC40 Indexer. Although this
connector is physically similar to the popular modular telephone connector, the terminal is not compatible
with telephone lines or signals. Connection to a telephone line will damage the terminal and voids the
warranty.
