Patton electronic 1070RC - Manual (Page 7)

3.2 DETAILED SWITCH SETTINGS
The following section provides detailed information about the
function of each DIP switch, and lists all possible settings. Use this
section as configuration guide for applications where the 1070RC's
default would not provide correct results.
Data Rate
Switches 1 thru 3 are set in combination to allow the Model
1070RC to be used at data rates from 1200 bps up to 19,200 bps.
Switch 1 Switch 2 Switch 3 Setting
On On On 1.2 Kbps
Off On On 2.4 Kbps
On Off On 4.8 Kbps
On On Off 7.2 Kbps
Off Off On 9.6 Kbps
Off On Off 14.4 Kbps
On Off Off 19.2 Kbps
Off Off Off 19.2 Kbps
Note: Switch 4 is not used.
6 5
Transmit Clock
Switch 5 is used to specify the clocking method. The Model
1070RC can provide an internal clock (Pin 15),or receive an external
clock (from Pin 24).
Switch 5
On = Internal
Off = External
RTS/CTS Delay
Switches 6 and 7 are used together to specify RTS/CTS delay.
After request to send (RTS) is raised by the host terminal, the 1070RC
raises CTS after a slight delay in order to give the remote terminal time
to receive an incoming signal. Depending on the type of environment,
either a 0 mS, 8 mS or 53 mS delay can be selected.
Switch 6 Switch 7
On On = 0 mS
On Off = 8 mS
Off Off = 53 mS
Carrier Enable
Switch 8 is used to specify how the carrier signal is raised. In most
point-to-point , full duplex applications, the carrier signal can remain
constantly "high". Important Note: In a multi-point environment, set
the host to "Constant Carrier" and each slave to "Controlled by RTS".
Switch 8
On = Controlled by RTS
Off = Constant Carrier
