PORT 1 and PORT 2 Connectors
Connector type: Standard DE9 male
Data Format: 8 data bits, 1 stop bit, no parity
Data Characteristics: A series of bytes entering the “PORT 1” or “PORT 2”
connectors must not have gaps between bytes greater than 500ms.
Handshaking: Activating the DSR input signal informs the NCB unit that the channel is
active. If the channel does not directly support DSR, it must be strapped
back to the (always active) DTR output signal.
Flow Control: CTS/RTS flow control can be used to pace the transmission of individual
bytes between the NCB and a connected device. Sensing of CTS by the
NCB can be enabled/disabled with the Option B switches. (See “STEP 2.
SWITCH SETUP”, in section “2. SETUP AND OPERATION”.)
