Revision C 250cx Series Maternal/Fetal Monitor 3-5
2036947-001
Installation: Connections
J104 Connector
This connector attaches to a standard Nurse Call System. The connector’s maximum
output is 50 Vdc at 100 mA; the maximum on resistance is 0.5 Ω. When connected
to a Nurse Call System, the monitor will activate the system each time a Spectra
Alert is issued. This interface simulates pressing the button on a bedside Nurse Call
System allowing nurses to respond to patient needs quickly and efficiently.
Although the J104 Nurse Call connector is physically present on the optional
communications package, this connector is only supported as part of the Spectra
Alerts option.
J109, J110, and J111 Connectors (RS-232C)
Three RS-232C serial interface connectors allow connecting the 250cx Series
Monitor to the following devices:
Nellcor Puritan Bennett (NPB) N-200 Maternal Oxygen Saturation Monitor
(J109 and J111 only)
DINAMAP
®
PRO Series 100-400 Monitors
DINAMAP
®
ProCare Monitors
Quantitative Sentinel/Perinatal System (any RS-232C connector)
When shipped from the GE factory, all three ports are configured as follows:
Communications Setup = Nellcor
baudrate (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.
1. Select the Service softkey from the General Setup screen.
2. The Service Lock screen appears.
3. Enter the correct access code; Install Options Screen 1 displays.
4. Select the COMM softkey on the bottom of Install Options Screen 1.
5. The Communications Setup screen appears.
6. Set the baudrate and mode for each port.
Baudrate
This field selects the baudrate and must be compatible with the external device. Use
the Trim Knob control to cycle through the available settings: 600, 1200, 2400, 4800,
9600, and 19,200 bps. (Each port is factory set to 1200 bps.)
