3.2.1 SWITCH SETTINGS
All possible settings for the Model 1004’s configuration switches
are presented in the summary table below. If you have additional
questions, contact Technical Support at (301) 975-1000.
SW 1-1: RTS/CTS Delay
The setting for Switch SW1-1 determines the amount of delay
between the time the Model 1004 “sees” RTS and when it sends CTS.
(This option is available in DCE mode only).
SW1-1 Setting
Off 0mS
On 8mS
SW 1-2: Echo Enable
Switch SW1-2 determines whether the Model 1004 echoes data
back to the transmitting device. (Half duplex modes only).
SW1-2 Setting
Off Echo Off
On Echo On
SW 1-3: Carrier Control Method
Switch SW1-3 determines whether the carrier is “constantly on” or
“controlled by RTS”. This setting allows for operation in switched carri-
er, multipoint and/or hardware handshaking applications.
SW1-3 Setting
Off Constantly “on”
On Controlled by RTS

Position Function Off Position On Position
SW1-1 RTS/CTS Delay 0mS 8mS
SW1-2 Echo Enable Echo “Off” Echo “On”
SW1-3 Carrier Control Constantly “On” Controlled by RTS
SW1-4 Impedance High (120K Ohm) Low (120 Ohm)
SW2 2 wire/4 wire 2-wire 4-wire
SW 1-4: Impedance
Switch SW1-4 defines a termination resistance. The Model 1004’s
generator can drive 50 unit loads including two termination resistances
of 120 Ohms each.
SW1-4 Setting
Off High (120K Ohm)
On Low (120 Ohm)
SW 2: 2-Wire/4-Wire
Switch SW1-4 determines whether the Model 1004 will operate in
either 2-wire or 4-wire mode.
SW1-4 Setting
Off 2-wire
On 4-wire
3.2.2 CONFIGURATION SWITCH APPLICATIONS
The table below shows you how to set the Model 1004's configu-
ration switches to fit several common applications. If you have any
questions, call Patton Technical Support at (301) 975-1007.
*NOTE: RTS/CTS Delay setting should be based upon transmission timing.
