5.1.4 Compatibility
The 7AF supports the following Establish Communications message formats for older Host implementations see "3.7.2
Gem Configuration”. If the Host intends to use the Control State Off-Line feature, CONFIGCONNECT should always be
set to S1F13/14.
S1F1/S1F2
S1F65/S1F66
5.2 Control States
This section describes the Control characteristics of the Equipment. The Equipment may be in one of the following
control states. This value is reflected in status variable CONTROLSTATE (VID 257).
Table 10 CONTROLSTATE Values
Value State
1 Off-Line/Equipment Off-Line
2 Off-Line/Attempt On-Line
3 Off-Line/Host Off-Line
4 On-Line/Local
5 On-Line/Remote
5.2.1 Control Finite State Description
The Control State of the Equipment is illustrated in the Control Finite State Diagram in paragraph 5.2.1. The 7AF
behaves differently and will accept different messages depending on its current control state. The purpose of this diagram
is to make clear to the Host exactly what is happening at the Equipment. The logic for these states and transitions is the
logic specified in the GEM standard.
