2015590-001
Peripheral Devices: Standard Input/Output Connectors
J109, J110, and J111 Connectors (RS-232C)
Three RS-232C serial interface receptacles allow connecting the 120 Series Monitor
to the following devices:
„ Nellcor Puritan Bennett (NPB) N-200 Maternal Oxygen Saturation Monitor
(J109 and J111 only)
„
Nellcor Puritan Bennett N-400 Fetal Oxygen Saturation Monitor
*
„ DINAMAP Model 1846, 1846SX, 8100, 8100T NIBP Monitors
„
DINAMAP Model 1846SX/Oxytrak Critical Care Monitor
„ Quantitative Sentinel/Perinatal System (any RS-232C connector)
When shipped from the GE factory, all three ports are configured as follows:
„ communications mode = NELLCOR
„
baud rate (bps) = 2400
At the above settings, connectors J109 and J111 are ready for connection to an NPB
Model N-200. Connector J110 does not support a connection to NPB monitors;
therefore, this connector will have to be configured for the device to which it is
attached.
