RM-2440 User Manual P/N 821574 Rev-C

Please refer to Figure-2b on the following page to familiarize yourself with the rear panel features of the RM-2440 unit. The

following sections describe these features and are referenced, by letter, to Figure-2b. See Figure-2c on page 12 for a top view of

the RM-2440 showing rear panel connector clearance dimensions.

Note about options: Figure-2b shows each of the two optional SDI Input Modules (RMSDI-1 and RMSDI-2) installed in

channels 1 and 2 and no option installed in channels 3 and 4. The SDI Input Modules may be installed in any combination (one per

display). Options are selected for monitoring by setting the associated A/B Source Select Switch on the front panel (Item 4, page

8) to the B position. For each section with an SDI Input Module installed, the CVBS Loop-Through Connector (Item C) will

output CVBS signals as converted from the SDI input. In any I/O section with an SDI Input Module option installed, the B CVBS

Input BNC connector should NOT be used, and it is recommended that it be covered with a connector cap to prevent its use.

Rear Panel Features

Section 2: Operation

Termination Switch (1A - 4A, 1B - 4B)

This switch terminates the CVBS Input Connector as required by your configuration. If you supply downstream

equipment from the CVBS Loop-Through Connector (Item C), then set this switch to the Hi-Z position. If not, set

this switch to the 75

ΩΩ

Ω position.

CVBS Input (IN) Connector (1A - 4A, 1B - 4B)

CVBS video signals may be connected here. NTSC or PAL standards are accommodated automatically. If signals are connected

at both the A and B inputs within the same I/O section, use the A/B Source Select Switch (Item 4, page 8) to select between the

two. Note: If an SDI Input Option module is installed in a B section, do NOT use the associated B CVBS input.

CVBS Loop-Through (OUT) Connector (1A - 4A, 1B - 4B)

Signal-through connections to downstream equipment are supplied at these BNC connectors. If you supply downstream

equipment from these connectors, ensure that you set the Termination Switch (Item A) according to your configuration.

Note that if an SDI Input Module (Item G) is installed in the same I/O section, this connector outputs a CVBS signal as

converted from the SDI Input Connector (Item Gc).

Option Connector (1-4)

This DE9 (9-pin) female connector allows you easily install an optional SDI Input Module (Item G).

Tally Control Connector

This 25-pin subminiature female “D” connector allows you to use the four front panel Tally Indication LEDs (Item 3,

page 10). Full connection instructions are described on pages 14 and 15.

Power Connector

Attach the supplied 110/220-12V external power supply between this connector and mains power.

Optional SDI Input Modules (RMSDI-1 and RMSDI-2)

There are two models of optional SDI Input Module; the RMSDI-1 and RMSDI-2. They are identical except that the

RMSDI-1 does not feature a SDI Output Connector (Item Gb) and must use the 525/625 Select Switch (Item Ge) to

select the NTSC/PAL format of the input signal (the RMSDI-2 does this automatically).

Note: See Figure-2c on page 12 for depth clearance dimensions of RM-2440 when RMSDI option modules are installed.

CVBS Output (Converted From SDI Input) Connector

When an optional RMSDI-1 or RMSDI-2 module is installed, this connector outputs CVBS signals as converted from the

SDI Input Connector (Item Gc). If this output is NOT used, set the associated Termination Switch (Item A) to 75

ΩΩ

Ω.

SDI Output Connector (RMSDI-2 Only)

SDI signal-through connections to down-stream equipment are supplied at this BNC connector. This connector

supplies a reclocked replica of the SDI input signal.

SDI Input Connector

Connect SDI signals to this female BNC connector, which is terminated at 75

ΩΩ

Ω.

SDI Lock Indication LED (GREEN)

When a valid (and locked) SDI signal is received at the SDI Input Connector (Item Gc) this LED lights GREEN.

525/625 (NTSC/PAL) Select Switch (RMSDI-1 Only)

On the RMSDI-1 (only), this switch is used to manually select for NTSC (525 line) or PAL (625 line) input signals.

Set the switch to the RIGHT to select PAL (625 lines), to the LEFT to select NTSC (525 lines).
