Steps	TO POWER THE MODEM USING THE KIT’S AC ADAPTER
Steps
	1. On the Modem Interface cable bridle (shown in Figure
	2-2), locate the DC POWER (red) and SIG GND (black)
	connectors. Then electrically isolate each connector by
	capping or taping it.
	Since you will be using the AC adapter instead of a DC
	power supply, it is important to isolate the DC power
	connectors to prevent shock.
	2. On the Modem Interface cable bridle (shown in Figure
	2-2), locate the RESET lead (yellow). Electrically isolate
	the RESET lead by capping or taping it.
	The RESET lead is designed to reset the GSP-1620
	modem whenever it is grounded for five seconds.
	Electrically isolating the lead prevents it from grounding
	and inadvertently resetting the modem.
	3. Locate the power connector in the middle of the
	Diagnostic cable (as shown in Figure 2-3), then plug the
	the AC wall adapter cable into the power connector.
	4. Tighten the lock ring on the adapter cable onto the
	locking threads of the power connector, so the adapter
	plug remains firmly seated in the power connector.
	The lock ring prevents the adapter cable and Diagnostic
	cable from inadvertently disconnecting and interrupting
	power to the modem.
	5. Make sure the switch on the Diagnostic cable is set to
	“POS 1 DTR to GND.”
	When this switch is set to “POS 1 DTR to GND,” DTR is
	asserted on the Diagnostic cable and the modem will
	power up immediately when power is applied.
	6. Plug the AC wall adapter (as shown in Figure 2-3) into an
	AC power wall outlet.
	You are now ready to use the modem.

Quick Bench Set-Up

Steps

1. On the Modem Interface cable bridle (shown in Figure

2-2), locate the DC POWER (red) and SIG GND (black)

connectors. Then electrically isolate each connector by

capping or taping it.

Since you will be using the AC adapter instead of a DC

power supply, it is important to isolate the DC power

connectors to prevent shock.

2-2), locate the RESET lead (yellow). Electrically isolate

the RESET lead by capping or taping it.

The RESET lead is designed to reset the GSP-1620

modem whenever it is grounded for five seconds.

Electrically isolating the lead prevents it from grounding

and inadvertently resetting the modem.

3. Locate the power connector in the middle of the

Diagnostic cable (as shown in Figure 2-3), then plug the

the AC wall adapter cable into the power connector.

4. Tighten the lock ring on the adapter cable onto the

locking threads of the power connector, so the adapter

plug remains firmly seated in the power connector.

The lock ring prevents the adapter cable and Diagnostic

cable from inadvertently disconnecting and interrupting

power to the modem.

5. Make sure the switch on the Diagnostic cable is set to

“POS 1 DTR to GND.”

When this switch is set to “POS 1 DTR to GND,” DTR is

asserted on the Diagnostic cable and the modem will

power up immediately when power is applied.

6. Plug the AC wall adapter (as shown in Figure 2-3) into an

AC power wall outlet.

You are now ready to use the modem.
