Table 7. Controls and indicators, DS-562I
Item Name/Description Function
1 LED indicator (green) ADR EN: Lights when the transmit address is enabled (not set to 0). Used in 56K mode only.
2 LED indicator (green) ADR VLD: Lights when the receive address is enabled (not set to 0) and matches the address
embedded in the T1/E1 signal. Used in 56K mode only.
3 LED indicator (red) EQ LB: Lights when the equipment loopback is enabled.
4 LED indicator (red) PL LB: Lights when the payload loopback is enabled.
5 LED indicator (green) RX: Lights when the DS-562I is receiving data from the remote equipment
6 LED indicator (green) TX: Lights when the DS-562I is transmitting data to the remote equipment
7 LED indicator (green) SVC: Lights when the DS-562I’s service is enabled.
8 Switch SW6 This is a three position toggle switch:
UP: Sets the board to equipment loopback.
Center: Normal operation (no loopback, but can be overridden remotely
).
Down: Sets the board to payload loopback.
NOTE: If this unit is used for protective relay
i
ng applications, disable the protection
equipment before using loopbacks.
9 DIP Switch SW7 SW7-1 to SW7-6 Sets the SCB address, see Table 7.
SW7-7 Sets the DS-562I service ON or OFF:
ON(up):
Service ON (board enabled).
OFF(down):
Service OFF (board disabled).
SW7-8 Sets the DS-562I for local or remote mode:
ON(up):
Local (settings obtained from DIP switches).
OFF(down):
Remote (settings obtained from SCB).
10 DIP Switch SW1 SW1-1 to SW1-5 Sets the T1/E1 timeslot, see Table 8.
11 DIP Switch SW2 SW2-1 to SW2-6 In 56 Kbps mode, sets the transmit address, see Table 9.
12 DIP Switch SW3 SW3-1 to SW3-6 In 56 Kbps mode, sets the receive address, see Table 9.
13 DIP Switch SW4 SW4-1 Enables/disables octet timing:
ON(right):
Octet timing OFF.
OFF(left):
Octet timing ON.
SW4-2 Sets the receive clock polarity:
ON(right): Normal polarity.
OFF(left): Inverted polarity.
SW4-3 Sets the transmit clock polarity:
ON(right): Normal polarity.
OFF(left): Inverted polarity.
SW4-4 Sets receiver squelch:
ON(right): Squelch OFF.
OFF(left):
Squelch ON (DS-562I stops output to user
equipment upon loss of valid address).
SW4-7 Sets the data rate:
ON(right): 64 Kbps.
OFF(left): 56 Kbps.
SW4-8 Sets the T1/E1 transmit bus direction:
ON(right):
Transmit on “B” (receive on “A”).
OF
F(left): Transmit on “A” (receive on “B”).
14 DIP Switch SW5 SW5-1 Selects the carrier type:
ON(right): T1 carrier.
OFF(left): E1 carrier.
SW5-2 Controls the handshaking delay:
ON(right): No delay.
OFF(left):
8 microseconds delay (approx.)
SW5-3 Selects Normal Data or Inverted Data:
ON(right): Normal Data.
O
FF(left): Inverted Data.
