When the mechanical installation has been completed, various strap-selectable

configurations must be set before the electrical installation can be completed.

Strapping is accomplished by setting DIP switch S2 (fig. 1-4). Switch S2 is on the

right center section of each rack-mounted converter board. See your system manual

for the switch position settings required for your system. An explanation of each

switch position is as follows:

a. RTS/RTS ON(S2-1). Switch S2-1 determines if Clear-to-Send

(CTS) is

RTS ON position,

controlled by Request-to-send (RTS) or is on continuously. In the

er Mode, and CTS

CTS is ON and the converter board is placed into the Constant Carri

terminal does

not supply an RTS signal. In the RTS position CTS is controlled by

b. Constant/Switched Carrier (S2-2). In the CONSTANT CARRIER position, S2-2

configures the converter board to operate in a constant carrier mode. In this mode

the converter's transmitter is always on. In the SWITCHED CARRIER position, S2-2

configures the converter board to operate in a Switched carrier mode. In this mode

the converter's transmitter is controlled by RTS. The SWITCHED CARRIER position is

over-ridden when S2-1 is in the RTS ON position.

c. RTS/CTS Delay (S2-3). Switch S2-3 selects either a 16 or 50 msec delay

between the time that RTS goes on and CTS is turned on.
