6.3.8 Master-Slave Protocol Output
Works with Port 2 (RS232 or RS485). By setting port 2 output method (parameter 3.t)
to any number between 65 and 90 [A-Z], you specify that the indicator should
participate in a network of several indicators. The number set in 3.t is this indicator’s
network address. For more details on the master-slave protocol supported by the
VT400, see Appendix B.
