Master/Slave

Please refer to the SentryPlus Service operation mode. If the computer connects to UPS

directly (with RS-232 or USB) and can send commands to its connected UPS then the

SentryPlus Service acts as a "Master". If it connects to UPS directly (with RS-232 or USB)

but only listens to UPS then it is a "Serial Slave". If the computer is powered by the UPS,

but obtains the UPS information from Master via TCP/IP network then it is a "Networking

Slave". When SentryPlus Service is a Networking Slave you must assign the Master IP

address so that the Networking Slave can connect to the Master and obtain the UPS

information.

a. Master: Configures the SentryPlus Service to be a Master.

b. Serial Slave: Configures the SentryPlus Service to be a Serial Slave.

c. Networking Slave: Configures the SentryPlus Service to be a Networking Slave.

d. Master IP Address: When SentryPlus Service is a Networking Slave you must assign

the Master IP address so that the Slave can connect to the Master host and obtain the

UPS information.
