HE693SNP232R   SNP to RS-232 Adapter

The HE693SNPCBL SNP to RS-232 Adapter is equipped with two ports. The 15-pin SNP port plugs directly into the PLC Programmer Port on the CPU rack power supply. Power to the SNP Adapter is supplied directly from the programming port (maximum 100mA@5VDC). The 9-pin RS-232 port connects to any RS-232 device.

The SNPCBL has a 90° cable exit for simplified cable routing. The SNPCBL adapter head has a RX (Receive) LED and a TX (Transmit) LED; both LEDs are green when active.
The pin-out for the SNPCBL Adapter serial ports is provided as follows. The direction indicated is with respect to the adapter. The following pin-outs are chosen to allow direct connection (using a straight through or 1 to 1 cable) to the IBM PC/AT. Nearly ALL of the IBM compatible computers equipped with a 9-pin RS232 port provide a pin-out compatible with that shown in Table 2.

When connecting the SNP adapter to IBM compatible PCs with hardware handshaking, the following cable interfaces are used.

The XT Adapter can be used on an IBM compatible PC, which has a 25-pin RS232 port. The internal wiring of the XT Adapter is in the following figure.
