1) CNTRL PORT

Used to set the unit up as the Master or Slave on a chain of units, and whether to initialize a modem and the control port data rate.

POSITION

Determines if this TSU is at the head of a chain of units (directly connected to the modem or PC). The head of the chain is referred to as the Master Unit. Units down the chain are referred to as Slaves or a Slave Unit.

The setting of the position selection is necessary only when using a modem, in which case the head unit should be Master. For all other cases, select SLAVE. (The Master is in charge for control of the modem.)

Choices: MASTER; SLAVE

MODEM INIT

The TSU is capable of initializing a modem. This menu selection is used to effect this initialization and should be selected only when the choice above designates the TSU as the MASTER. Prior to modem initialization it should be physically connected to the TSU and the power turned on. At this point, an industry-standard AT command string is used to initialize the modem. The string is also used following future power-up sequences.

Choices: ENAB - Enable; DISA - Disable
