3.2.1.
Connecting to a Modem
When connecting directly to an external modem, use a standard
AT to Modem cable. Make certain the modem is initialized at
the same baud rate as the RPB+ (SetUp Switch 1). The modem
must be placed in Auto-Answer mode, and set to answer in one
ring. Please refer to the user’s guide for your external modem in
order to determine the appropriate AT command string.
3.3.
Power Connection
The Power Switch located on the back panel must be “On” in
order for the RPB+ to operate. Each time the unit is powered
On, the five AC outlets will be switched On or Off, as dictated
by the Power-Up Default String (see Section 4.1). Each outlet is
capable of switching up to 15 Amps of AC power. The total for
all 5 outlets cannot exceed 15 Amps.
